Animals are however not particularly warmth tolerant; very few of them can survive at fixed temperatures above 50 °C (122 °F). Only very few species of animals inhabit essentially the most extreme cold deserts of continental Antarctica. Rhinoceroses are herbivorous, browsers or grazers in accordance with the species.

Most reside near water and prefer to wallow in mud; all swim properly. They have poor vision but good hearing and a good sense of smell.

Owls superficially resemble quick-necked hawks, except that their eyes are directed forward and are surrounded by disks of radiating feathers.

This may be calcified, forming buildings corresponding to shells, bones, and spicules.
