Natural Resource Damage Assessment (NRDA) |
Marine mammals are mammals that are well adapted for life in the marine environment. Two major groups of marine mammals are:
- Cetaceans:
- Pinnipeds:
There are approximately 217 marine mammal species worldwide managed under the MMPA.
All marine mammals are protected under the Marine Mammal Protection Act (MMPA); some marine mammals may be designated as "depleted" under the MMPA. Endangered and threatened marine mammals are also protected under the Endangered Species Act (ESA). Stocks of marine mammals may also be considered "strategic" under the MMPA. A list of strategic/ non-strategic stocks [pdf] can be found in the summary tables of the Stock Assessment Reports.
The following list of marine mammals includes those under our jurisdiction, which includes marine mammal species found in U.S. waters, as well as endangered/ threatened species worldwide.
(The U.S. Fish and Wildlife Service manages walrus, polar bear, otter, manatee, and dugong.)

Marine Mammal Conservation
We work in collaboration with our Regional Offices, Science Centers, and partners to develop and implement a variety of programs for the protection, conservation, and recovery of the approximately 160 marine mammal stocks listed under the MMPA, including:
- Developing and implementing Conservation Plans for species designated as depleted
- Establishing cooperative agreements with states and Alaska Natives regarding marine mammal resources
- Identifying important research needs to collect appropriate information for management decisions
- Managing the Marine Mammal Health and Stranding Response Program
- Administering the national program for display of captive whales, dolphins, porpoises, seals, and sea lions
- Coordinating with the USFWS on issues concerning the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
- Administering various authorizations and permits
- Reducing and mitigating bycatch in U.S. commercial fisheries
