Urgent! Public Comments Needed To Help Protect Critically Endangered Atlantic Humpback Dolphins Under The Endangered Species Act

The National Marine Fisheries Service (NMFS) recently announced that it would begin a status review to determine whether the highly imperiled Atlantic humpback dolphin should be protected under the Endangered Species Act (ESA). The agency’s decision came in response to a September petition filed by the Animal Welfare Institute, Center for Biological Diversity, and VIVA Vaquita.

As previously reported by WAN, Atlantic humpback dolphin populations are in serious decline, and the species is already recognized as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

The “90-day finding” under the ESA determined that the animal welfare and conservation groups presented “substantial scientific or commercial information indicating that the petitioned action may be warranted.” It is the first procedural step to significantly improve the species’ survival prospects by increasing global awareness, generating funds for important science, and providing financial, legal, political, and enforcement assistance to local and international conservation efforts.

“This was fantastic news,” Dr. Naomi Rose, marine mammal scientist at The Animal Welfare Institute, told WAN. “These dolphins need to have a higher profile, and lots of international assistance, if they are to survive. An Endangered Species Act listing will help with that.”

As noted by AWI, the Atlantic humpback dolphin is the most endangered of the four species of coastal humpback dolphins, which are all threatened by human activities. The species is found only along the western coast of Africa, ranging through at least 13 countries from Western Sahara south to Angola. Scientists estimate that no more than 3,000 Atlantic humpback dolphins remain in fragmented groups of tens to hundreds of animals. They are at “an extremely high-risk of extinction in the wild,” according to the IUCN.

The major threat to the dolphins is bycatch by local gillnet fisheries. The animals are unintentionally caught and killed by fishing gear. These and other fisheries also deplete the dolphins’ prey. Other major threats include coastal development and noise from human activity. The market for Atlantic humpback dolphin meat also appears to be growing as part of the African aquatic wild meat trade.

“Without federal protections, Atlantic humpback dolphins could disappear before most people can even hear about them,” said Sarah Uhlemann, international program director at the Center for Biological Diversity. “This is a first critical step to saving these adorable but little-known dolphins from fishing net entanglements and other threats.”

Atlantic humpback dolphins, with distinctive humps on their backs topped by rounded dorsal fins, live exclusively in relatively shallow waters and are most common in estuarine environments close to shore.

Atlantic humpbacks are among the least-known species of dolphins or porpoises in the world, and this has hindered effective conservation measures. Current measures and regulations aimed at protecting this species are woefully inadequate. Although marine protected areas exist in some countries in the dolphins’ range, they have limited effectiveness because few laws or regulations exist specifically to conserve the species.

“In the past two decades, we have lost one species of dolphin, the baiji or Yangtze River dolphin, and a species of porpoise, the vaquita, is on the brink,” noted Thomas A. Jefferson, director of VIVA Vaquita. “It is critical that we act now to make sure that the Atlantic humpback dolphin does not join a list of species that are going extinct simply because we are not affording them adequate protection.”

At the conclusion of its status review, NMFS will issue a 12-month petition finding, which will determine whether the agency will propose the Atlantic humpback dolphin for listing under the ESA.

A 60-day comment period soliciting public input is now open. Information on how the public can leave their comments to support protecting Atlantic humpback dolphins under the Endangered Species Act, which must be received by January 31, 2022, is available HERE!
