Wading and bottom-feeding animals (e.g. moose and manatee) need to be heavier than water in order to keep contact with the floor or to stay submerged, surface-living animals (e.g. otters) need the opposite, and free-swimming animals living in open waters (e.g. dolphins) need to be neutrally buoyant in order to be able to swim up and down the ...
In animals, rabies is a viral zoonotic neuro-invasive disease which causes inflammation in the brain and is usually fatal. Rabies, caused by the rabies virus , primarily infects mammals. In the laboratory it has been found that birds can be infected, as well as cell cultures from birds, reptiles and insects. [ 1 ]
Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...
By necessity, terrestrial animals in captivity become accustomed to drinking water, but most free-roaming animals stay hydrated through the fluids and moisture in fresh food, [2] and learn to actively seek foods with high fluid content. [3] When conditions impel them to drink from bodies of water, the methods and motions differ greatly among ...
It raises fewer young which grow more slowly than other marsupials of its size, because of the time-consuming effort of nectar-drinking from many flowers to support itself. It may spend periods in deep sleep to reduce its need for food, and shows the typical nectarivore adaptations for excess water-removal. [19]
A zoo has been giving its animals warm meals and drinks to help them through the cold weather. Jodie Bryant, head of primates at Dudley Zoo and Castle, said: "The main thing is we're providing ...
Another said, “The kittens got me to drink water, too… yay for hydration!” A third added, “The water bowl is like an ocean for him.” Kittens, like many young animals, have specific needs ...
Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America.The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g., dipodids and hopping mice).
