The Maryland Zoo in Baltimore houses African elephants (Loxodonta africana) who are very different from their Asian elephant (Elephas maximus) cousins. The African elephant (Loxodonta africana) is the largest land animal in the world.he forest elephant is generally smaller, with rounder ears, and tusks that grow downward. Normally, forest elephants inhabit the rain forests of central and western Africa and do not overlap the territories of the savannah elephant.
Mammoths, like their elephant cousins of today, would have been adapted to the warm climate they evolved in. In these climates, an elephant's biggest problem is getting rid of heat -- they do this with their big ears, through which many heat-porting blood vessels circulate. new study has found tiny genetic mutations that changed the way oxygen was delivered by its blood could be responsible for its tolerance to the cold climate. The woolly mammoth was an elephantid species and most closely related to today's Asian elephants.
