Endangered and Threatened Wildlife; 90-Day Finding on a Petition 
To List the Black Teatfish as Threatened or Endangered Under the 
Endangered Species Act

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: 90-Day petition finding, request for information, and 
initiation of status review.

-----------------------------------------------------------------------

SUMMARY: We, NMFS, announce a 90-day finding on a petition to list the 
black teatfish (Holothuria nobilis) as threatened or endangered under 
the Endangered Species Act (ESA). We find that the petition presents 
substantial scientific or commercial information indicating that the 
petitioned action may be warranted. Therefore, we are initiating a 
status review of the species to determine whether listing under the ESA 
is warranted. To ensure this status review is comprehensive, we are 
soliciting scientific and commercial information regarding this 
species.

SUPPLEMENTARY INFORMATION:

Background

    On May 14, 2020, we received a petition from the Center for 
Biological Diversity to list the black teatfish (Holothuria nobilis) as 
a threatened or endangered species under the ESA. The petition asserts 
that H. nobilis is threatened by four of the five ESA section 4(a)(1) 
factors: (1) Present and threatened modification of its habitat; (2) 
overutilization for commercial purposes; (3) inadequacy of existing 
regulatory mechanisms; and (4) other natural or manmade factors. The 
petition is available online (see ADDRESSES).

ESA Statutory, Regulatory, and Policy Provisions and Evaluation 
Framework

    Section 4(b)(3)(A) of the ESA of 1973, as amended (16 U.S.C. 1531 
et seq.), requires, to the maximum extent practicable, that within 90 
days of receipt of a petition to list a species as threatened or 
endangered, the Secretary of Commerce make a finding on whether that 
petition presents substantial scientific or commercial information 
indicating that the petitioned action may be warranted, and to promptly 
publish such finding in the Federal Register (16 U.S.C. 1533(b)(3)(A)). 
When it is found that substantial scientific or commercial information 
in a petition indicates the petitioned action may be warranted (a 
``positive 90-day finding''), we are required to promptly commence a 
review of the status of the species concerned during which we will 
conduct a comprehensive review of the best available scientific and 
commercial information. In such cases, we conclude the review with a 
finding as to whether, in fact, the petitioned action is warranted 
within 12 months of receipt of the petition. Because the finding at the 
12-month stage is based on a more thorough review of the available 
information, as compared to the narrow scope of review at the 90-day 
stage, a ``may be warranted'' finding does not prejudge the outcome of 
the status review.
    Under the ESA, a listing determination may address a species, which 
is defined to also include subspecies and, for any vertebrate species, 
any distinct population segment (DPS) that interbreeds when mature (16 
U.S.C. 1532(16)). A joint NMFS-U.S. Fish and Wildlife Service (USFWS) 
(jointly, ``the Services'') policy clarifies the agencies' 
interpretation of the phrase ``distinct population segment'' for the 
purposes of listing, delisting, and reclassifying a species under the 
ESA (61 FR 4722; February 7, 1996). A species, subspecies, or DPS is 
``endangered'' if it is in danger of extinction throughout all or a 
significant portion of its range, and ``threatened'' if it is likely to 
become endangered within the foreseeable future throughout all or a 
significant portion of its range (ESA sections 3(6) and 3(20), 
respectively, 16 U.S.C. 1532(6) and (20)). Pursuant to the ESA and our 
implementing regulations, we determine whether species are threatened 
or endangered based on any one or a combination of the following five 
section 4(a)(1) factors: (1) The present or threatened destruction, 
modification, or curtailment of habitat or range; (2) overutilization 
for commercial, recreational, scientific, or educational purposes; (3) 
disease or predation; (4) inadequacy of existing regulatory mechanisms 
to address identified threats; (5) or any other natural or manmade 
factors affecting the species' existence (16 U.S.C. 1533(a)(1), 50 CFR 
424.11(c)).
    ESA-implementing regulations issued jointly by NMFS and USFWS (50 
CFR 424.14(h)(1)(i)) define ``substantial scientific or commercial 
information'' in the context of reviewing a petition to list, delist, 
or reclassify a species as credible scientific or commercial 
information in support of the petition's claims such that a reasonable 
person conducting an impartial scientific review would conclude that 
the action proposed in the petition may be warranted. Conclusions drawn 
in the petition without the support of credible scientific or 
commercial information will not be considered ``substantial 
information.'' In reaching the initial (90-day) finding on the 
petition, we will consider the information described in sections 50 CFR 
424.14(c), (d), and (g) (if applicable).
    Our determination as to whether the petition provides substantial 
scientific or commercial information indicating that the petitioned 
action may be warranted will depend in part on the degree to which the 
petition includes the following types of information: (1) Information 
on current population status and trends and estimates of current 
population sizes and distributions, both in captivity and the wild, if 
available; (2) identification of the factors under section 4(a)(1) of 
the ESA that may affect the species and where these factors are acting 
upon the species; (3) whether and to what extent any or all of the 
factors alone or in combination identified in section 4(a)(1) of the 
ESA may cause the species to be an endangered species or threatened 
species (i.e., the species is currently in danger of extinction or is 
likely to become so within the foreseeable future), and, if so, how 
high in magnitude and how imminent the threats to the species and its 
habitat are; (4) information on adequacy of regulatory protections and 
effectiveness of conservation activities by States as well as other 
parties, that have been initiated or that are ongoing, that may protect 
the species or its habitat; and (5) a complete, balanced representation 
of the relevant facts, including information that may contradict claims 
in the petition. See 50 CFR 424.14(d).
    If the petitioner provides supplemental information before the 
initial finding is made and states that it is part of the petition, the 
new information, along with the previously submitted information, is 
treated as a new petition that supersedes the original petition, and 
the statutory timeframes will begin when such

[[Page 48146]]

supplemental information is received. See 50 CFR 424.14(g).
    We may also consider information readily available at the time the 
determination is made. We are not required to consider any supporting 
materials cited by the petitioner if the petitioner does not provide 
electronic or hard copies, to the extent permitted by U.S. copyright 
law, or appropriate excerpts or quotations from those materials (e.g., 
publications, maps, reports, letters from authorities). See 50 CFR 
424.14(c)(6).
    The ``substantial scientific or commercial information'' standard 
must be applied in light of any prior reviews or findings we have made 
on the listing status of the species that is the subject of the 
petition. Where we have already conducted a finding on, or review of, 
the listing status of that species (whether in response to a petition 
or on our own initiative), we will evaluate any petition received 
thereafter seeking to list, delist, or reclassify that species to 
determine whether a reasonable person conducting an impartial 
scientific review would conclude that the action proposed in the 
petition may be warranted despite the previous review or finding. Where 
the prior review resulted in a final agency action--such as a final 
listing determination, 90-day not-substantial finding, or 12-month not-
warranted finding--a petition will generally not be considered to 
present substantial scientific and commercial information indicating 
that the petitioned action may be warranted unless the petition 
provides new information or analysis not previously considered. See 50 
CFR 424.14(h)(1)(iii).
    At the 90-day finding stage, we do not conduct additional research, 
and we do not solicit information from parties outside the agency to 
help us in evaluating the petition. We will accept the petitioners' 
sources and characterizations of the information presented if they 
appear to be based on accepted scientific principles, unless we have 
specific information in our files that indicates the petition's 
information is incorrect, unreliable, obsolete, or otherwise irrelevant 
to the requested action. Information that is susceptible to more than 
one interpretation or that is contradicted by other available 
information will not be dismissed at the 90-day finding stage, so long 
as it is reliable and a reasonable person conducting an impartial 
scientific review would conclude it supports the petitioners' 
assertions. In other words, conclusive information indicating the 
species may meet the ESA's requirements for listing is not required to 
make a positive 90-day finding. We will not conclude that a lack of 
specific information alone necessitates a negative 90-day finding if a 
reasonable person conducting an impartial scientific review would 
conclude that the unknown information itself suggests the species may 
be at risk of extinction presently or within the foreseeable future.
    To make a 90-day finding on a petition to list a species, we first 
evaluate whether the information presented in the petition, in light of 
the information readily available in our files, indicates that the 
petitioned entity constitutes a ``species'' eligible for listing under 
the ESA. Next, if we conclude the petition presents substantial 
scientific or commercial information suggesting that the petitioned 
entity may constitute a ``species,'' we evaluate whether the 
information indicates that the species may face an extinction risk such 
that listing, delisting, or reclassification may be warranted; this may 
be indicated in information expressly discussing the species' status 
and trends, or in information describing impacts and threats to the 
species. We evaluate whether the petition presents any information on 
specific demographic factors pertinent to evaluating extinction risk 
for the species (e.g., population abundance and trends, productivity, 
spatial structure, age structure, sex ratio, diversity, current and 
historical range, habitat integrity or fragmentation), and the 
potential contribution of identified demographic risks to extinction 
risk for the species. We then evaluate whether the petition presents 
information suggesting potential links between these demographic risks 
and the causative impacts and threats identified in section 4(a)(1) of 
the ESA.
    Information presented on impacts or threats should be specific to 
the species and should reasonably suggest that one or more of these 
factors may be operative threats that act or have acted on the species 
to the point that it may warrant protection under the ESA. Broad 
statements about generalized threats to the species, or identification 
of factors that could negatively impact a species, do not constitute 
substantial information indicating that listing may be warranted. We 
look for information indicating that not only is the particular species 
exposed to a factor, but that the species may be responding in a 
negative fashion; then we assess the potential significance of that 
negative response.
    Many petitions identify risk classifications made by 
nongovernmental organizations, such as the International Union on the 
Conservation of Nature (IUCN), the American Fisheries Society, or 
NatureServe, as evidence of extinction risk for a species. Risk 
classifications by other organizations or made under other Federal or 
state statutes may be informative, but such classification alone may 
not provide the rationale for a positive 90-day finding under the ESA. 
For example, as explained by NatureServe, their assessments of a 
species' conservation status do ``not constitute a recommendation by 
NatureServe for listing under the U.S. Endangered Species Act'' because 
NatureServe assessments ``have different criteria, evidence 
requirements, purposes and taxonomic coverage than government lists of 
endangered and threatened species, and therefore these two types of 
lists should not be expected to coincide'' (https://explorer.natureserve.org/AboutTheData/DataTypes/ConservationStatusCategories). Additionally, species classifications 
under IUCN and the ESA are not equivalent; data standards, criteria 
used to evaluate species, and treatment of uncertainty are also not 
necessarily the same. Thus, when a petition cites such classifications, 
we will evaluate the source of information that the classification is 
based upon in light of the standards on extinction risk and impacts or 
threats discussed above.

Taxonomy

    Morphological characteristics were historically used to distinguish 
between teatfish species, though morphological features alone were 
determined to be unreliable markers of identification due to high 
interspecies variability (Uthicke et al. 2004). The more recent use of 
molecular analyses resolved taxonomic confusion between teatfish in the 
western Indian Ocean and southwestern Pacific Oceans, distinguishing 
between three species: (1) Holothuria whitmaei: Black/dark brown 
specimens found in waters of Australia and the southwest Pacific; (2) 
H. fuscogilva: White/beige specimens with dark markings broadly 
distributed throughout the tropical Indo-Pacific; and (3) H. nobilis: 
Black specimens with white ventro[hyphen]lateral patches found in the 
western Indian Ocean (Uthicke et al. 2004). The two black teatfish (H. 
whitmaei, with distribution in the Pacific Ocean, and H. nobilis, with 
distribution in the Indian Ocean) appear to be allopatric with a 
genetic distance of 9.2 percent, implying a divergence during the 
Pliocene of approximately 1.8-4.6 million years (Uthicke et al. 2004). 
Further molecular analyses support the distinction between H. nobilis 
and H. fuscogilva, once considered synonyms, as different

[[Page 48147]]

species (Ahmed et al. 2016). We conclude that the petitioned entity, H. 
nobilis, constitutes a species eligible for listing under the ESA.

Distribution, Habitat, and Life History

    The black teatfish occurs in coral reef habitats between 0 and 40 
meters depth, and is most commonly found in reef flats and outer reef 
slopes with a preference for hard substrates (CITES 2019; Conand et al. 
20013; Eriksson et al. 2012; Idreesbabu and Sureshkumar 2017; Lawrence 
et al. 2004). The species may also be found in shallow seagrass beds 
(CITES 2019; Conand et al. 2013). H. nobilis is distributed in the 
Indian Ocean, including along the east coast of Africa, the Red Sea, 
and coastal waters of Madagascar, La Reunion, Yemen, Oman, the west 
coast of India, Sri Lanka, Seychelles, Comoros, and the Maldives 
(Conand et al. 2013; Uthicke et al. 2004).
    Sea cucumbers of the order Aspidochirotida, including H. nobilis, 
are deposit and detritus feeders that digest organic matter such as 
bacteria in the top few millimeters of sediment (as reviewed by Purcell 
et al. 2016). Teatfish are non-migratory and relatively sedentary, with 
slow growth rates and longevity estimated at several decades (FAO 
2019). Teatfish generally mature at 3-7 years (FAO 2019), and H. 
nobilis is reported to mature at 4 years (Conand et al. 2013). Teatfish 
reproduce sexually through broadcast spawning, therefore successful 
fertilization depends upon density and proximity of male and female 
teatfish to one another (CITES 2019; FAO 2019; Purcell et al. 2010; 
Purcell et al. 2011). As teatfish generally exhibit low natural 
mortality rates, low to moderate population growth, and suspected high 
larval mortality, their overall productivity is low (CITES 2019; FAO 
2019).

Abundance and Population Trends

    Although data on abundance and population trends for H. nobilis are 
sparse, available data indicate that the species has declined by 60-70 
percent across at least 80 percent of its range since the 1960s, and 
continues to decrease (CITES 2019; Conand et al. 2013). Intense 
pressure from harvest for international trade has resulted in extremely 
low densities or no black teatfish observed at surveyed sites 
throughout its range with few exceptions, and these observations are 
matched by decreased exports (FAO 2019). In Madagascar and Egypt, very 
few individuals of the species have been observed and stocks are 
considered depleted due to overexploitation (CITES 2019). In Tanzania, 
where H. nobilis once dominated the catch, the species now makes up a 
very small percentage of sea cucumber species harvested (CITES 20129; 
Conand et al. 2013). The species has also been depleted in Mozambique, 
India, Sri Lanka, the Red Sea, Maldives, and likely in Tanzania and 
Kenya, due to overfishing (Conand et al. 2013; Purcell et al. 2012). In 
Seychelles, harvest of H. nobilis was stable from 2003-2006 and harvest 
peaked at 10,371 individuals, and then fell in 2007 and 2008 to 5,687 
individuals; this fishery is likely not depleted (Conand et al. 2013). 
Though teatfish harvest in small-scale, artisanal fisheries has 
generally not been monitored long-term, H. nobilis abundance is 
considered low compared to recognized baselines, and populations are 
declining throughout their range (FAO 2019).

Analysis of ESA Section 4(a)(1) Factors

    The petition asserts that H. nobilis is threatened by four of the 
five ESA section 4(a)(1) factors: Present and threatened modification 
of coral reef and seagrass bed habitat, overutilization for commercial 
trade, inadequacy of existing regulatory mechanisms to control the 
threats of trade, fisheries and climate change, and other natural or 
manmade factors including a lack of basic biological and ecological 
information, risks of rarity, and bycatch. The primary threat facing 
the species is overharvest for commercial international trade (CITES 
2019; FAO 2019), and we find that listing the black teatfish as a 
threatened or endangered species under the ESA may be warranted based 
on this threat alone. As such, we focus our discussion below on the 
evidence of overutilization for commercial purposes. However, we note 
that in the status review for this species, we will evaluate all ESA 
section 4(a)(1) factors to determine whether any one or a combination 
of these factors are causing declines in the species or likely to 
substantially negatively affect the species within the foreseeable 
future to such a point that the black teatfish is at risk of extinction 
or likely to become so in the foreseeable future.

Overutilization for Commercial, Recreational, Scientific, or 
Educational Purposes

    An estimated 10,000 tons of dried and processed sea cucumber are 
traded internationally each year, corresponding to about 200 million 
individuals harvested from marine ecosystems annually (Purcell et al. 
2016). H. nobilis is one of the most highly valued sea cucumber species 
in the Indo-Pacific region (Bruckner 2006; Conand 2018; Conand et al. 
2013; Muthiga & Conand 2013) and is sold dried and processed as 
``beche-de-mer'' primarily to luxury food markets in Hong Kong, 
Singapore, Taiwan, China, Korea and Malaysia (CITES 2019; Purcell et 
al. 2012). Black teatfish is sold for $20 to $80/kg dry weight, 
depending on size and condition; prices in Hong Kong retail markets 
range from $106 to $139/kg dried (Purcell et al. 2012). Since the 
1980s, the global sea cucumber fishery has dramatically increased in 
terms of number of producing countries, number of exploited species, 
increased fishing effort, and expanded fishing areas, leading to 
overexploitation and depletion of teatfish in most range countries 
(CITES 2019).
    Several of the black teatfish's life history traits make it 
vulnerable to overexploitation, including its low mobility, slow 
growth, late maturity, density-dependent reproduction, and low 
recruitment rates (CITES 2019; FAO 2019). These traits, combined with 
its occurrence in shallow, easily accessible waters, and high value in 
international markets, have led to local extirpations and depletion of 
stocks throughout most of its range (CITES 2019; FAO 2019). The species 
is estimated to have declined between 60-70 percent over at least 80 
percent of its range, as evidenced by vastly reduced catch per unit 
effort, reduced sizes of harvested individuals, and extremely low 
observed population densities (Conand et al. 2013). For example, 
transect data reveal population densities of 0.66 and 1.0 individuals 
per hectare in nearshore waters off Egypt and Eritrea, respectively, 
and range-wide density is estimated between 0.12 and 10 individuals per 
hectare (Conand et al. 2013). Even with fishery closures, sea cucumber 
stocks may recover slowly, potentially taking decades for populations 
to be restored (Anderson et al. 2011). Due to high demand that is not 
being met by current beche-de-mer production, fisheries pressure on the 
species is expected to continue (Conand et al. 2013; FAO 2019; Muthiga 
& Conand 2013). The information presented in the petition and briefly 
summarized here regarding the threat of overutilization for commercial 
purposes indicates that H. nobilis may be in danger of extinction or 
likely to become so in the foreseeable future throughout all or a 
significant portion of its range.

Petition Finding

    After reviewing the petition, the literature cited in the petition, 
and other information readily available in our files, we find that 
listing H. nobilis as a threatened or endangered species may

[[Page 48148]]

be warranted. Therefore, in accordance with section 4(b)(3)(A) of the 
ESA and NMFS' implementing regulations (50 CFR 424.14(h)(2)), we will 
commence a status review of this species. During the status review, we 
will determine whether H. nobilis is in danger of extinction 
(endangered) or likely to become so (threatened) throughout all or a 
significant portion of its range. As required by section 4(b)(3)(B) of 
the ESA, within 12 months of the receipt of the petition (May 14, 
2020), we will make a finding as to whether listing the black teatfish 
as an endangered or threatened species is warranted. If listing is 
warranted, we will publish a proposed rule and solicit public comments 
before developing and publishing a final rule.

Information Solicited

    To ensure that the status review is based on the best available 
scientific and commercial data, we are soliciting comments and 
information from interested parties on the status of the black 
teatfish. Specifically, we are soliciting information in the following 
areas:
    (1) Historical and current abundance, density, and distribution of 
H. nobilis;
    (2) Historical and current condition of habitat for H. nobilis;
    (3) The effects of harvest for commercial international trade on 
the distribution and abundance of H. nobilis over the short- and long-
term;
    (4) The effects of other known or potential threats, including 
coral reef and seagrass bed degradation, climate change, disease and 
predation, and the inadequacy of existing regulatory mechanisms, on the 
distribution and abundance of H. nobilis over the short- and long-term; 
and
    (5) Management or conservation programs for H. nobilis, including 
mitigation measures related to any of the threats listed above.
    We request that all data and information be accompanied by 
supporting documentation such as maps, bibliographic references, or 
reprints of pertinent publications. Please send any comments to one of 
the ADDRESSES listed above. We will base our findings on a review of 
the best available scientific and commercial information available, 
including all information received during the public comment period.
