The 1979 Convention on the Conservation of Migratory Species of Wild Animals (CMS) is the only global organization that conserves a broad range of animals, which includes marine mammals. [ 126 ] [ 127 ] Of the agreements made, three of them deal with the conservation of marine mammals: ACCOBAMS , ASCOBANS and the Wadden Sea Agreement . [ 128 ]
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.
Increased ocean traffic causes collisions between fast ocean vessels and large marine mammals. [42] Habitat degradation also threatens marine mammals and their ability to find and catch food. Noise pollution, for example, may adversely affect echolocating mammals, [43] and the ongoing effects of global warming degrades arctic environments. [44]
In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes). [1]
They photographed the “large” sea animals and captured two. Taking a closer look, researchers realized they’d discovered a new species: Zancleopsis grandis, or the large Zancleopsis jellyfish.
Unlike other sea spiders, the new species’ fixed and movable fingers close completely, leaving “no space present between fingers.” Photos show the animal’s claws, including the bristles ...
The recently extinct Steller's sea cow was the largest known sirenian to have lived, reaching lengths of 10 metres (33 feet) and weights of 5 to 10 tonnes (5.5 to 11.0 short tons). [ 2 ] Sirenians have a large, fusiform body which reduces drag through the water and heavy bones that act as ballast to counteract the buoyancy of their blubber .
