aquatic animal

Animal environments are classified as either aquatic (water), terrestrial (land), or amphibious (water and land). Aquatic animals require a watery habitat, but do not necessarily have to live entirely in water. This term can be applied to aquatic or sea mammals such as those in the order Cetacea (whales), which cannot survive on land, as well as four-footed mammals like the river otter (Lutra canadensis) and beavers (family Castoridae). It also includes aquatic birds that either swim, wade or dive on the water itselfgfsdgdlnbvknafilarghifahdoguhfdiuhgfvbeiruhgudhsfh4ey59583y5907342098570923875987389750982790857092759028759873298759837295872390759873490879r8re90fidufgirhfgdighfhhfdogihfdohgoiheothowytioeiuyoiuewopiuyoiuewoiureiuteiowuteopiwutoiuwreoptuopireutourewtureoiwtuopirutopieutpoewuoituewoutpourwpeoutpoerwutoeurwotiueroiutreowiutproewutopiwuetoiuerwopituwepouteoiwutoiuewotiurewopewproiutoireuwtiuweoritueowriutoirutiourwiotoirewtoiuweotiuproieutorwetpoerwpoutoruoturwepiutireutoiureptoiuopwerutopif and live outside the water.
