Marine mammals that live in coastal environments are the most likely to be affected by habitat degradation and loss. Developments such as sewage marine outfalls , moorings , dredging , blasting, dumping, port construction, hydroelectric projects, and aquaculture both degrade the environment and take up valuable habitat.

The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders. The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1] This list follows the Society's taxonomy regarding and subspecies.
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare , meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species . [ 1 ]
Despite their underwater habitat, whales are mammals. Mammals are not solely terrestrial; some, including whales and dolphins, are fully aquatic the University of Michigan Museum of Zoology reports.
Marine mammal rehabilitation programs have been underway and regulated in the United States for more than 40 years. In 1973, injured and distressed manatees were rescued or aided in Florida. Eventually, the program was formalized into the Manatee Rescue, Rehabilitation, and Release Program managed by the US Fish and Wildlife Service.
Manatees (/ ˈ m æ n ə t iː z /, family Trichechidae, genus Trichechus) are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows.There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis), the West Indian manatee (Trichechus manatus), and the West ...
Bycatch, which is the incidental catch of non-target species in fishing gear, is not only the largest threat to the survival of the vaquita, but to all marine mammals around the world. [ 42 ] [ 43 ] [ failed verification ] A series of simulations in a 2022 study indicate that the species has a chance to survive and recover if all bycatch is ...
