Likewise, their diet ranges considerably as well; some may eat zooplankton, [28] others may eat small fish, [29] and a few may eat other mammals. [30] While the number of marine mammals is small compared to those found on land, their roles in various ecosystems are large.
Despite the benefits domesticated mammals had for human development, humans have an increasingly detrimental effect on wild mammals across the world. It has been estimated that the mass of all wild mammals has declined to only 4% of all mammals, with 96% of mammals being humans and their livestock now (see figure). In fact, terrestrial wild ...
The diets of marine mammals vary considerably as well; some eat zooplankton, others eat fish, squid, shellfish, or seagrass, and a few eat other mammals. While the number of marine mammals is small compared to those found on land, their roles in various ecosystems are large, especially concerning the maintenance of marine ecosystems, through ...

A number of invertebrate species have been introduced since the arrival of Europeans, some filling niches that were not previously filled. House sparrows and domestic geese are the only introduced bird species. Introduced fish species exist, such as the brown trout. Twenty-two introduced plant species are thought to provide a significant threat ...
Cetartiodactyla is a large order of hoofed mammals, the even-toed ungulates, and aquatic mammals, cetaceans. Cetacea was found to be nested within "Artiodactlya" and has now been moved into that order, whose name is now Cetartiodactyla. [2] Even-toed ungulates are found nearly world-wide, although no species are native to Australia or Antarctica.
The olm (German: ⓘ) or proteus (Proteus anguinus) is an aquatic salamander which is the only species in the genus Proteus of the family Proteidae [2] and the only exclusively cave-dwelling chordate species found in Europe; the family's other extant genus is Necturus.
