I want to know why elephants and other animals
bearing resemblance to it are called pachyderms?
The word pachyderm is defined as: any of the thick-skinned,
nonruminant ungulates, as the elephant, hippopotamus, and rhinoceros.
In systematics, the order pachydermata is no longer in use. Those
animals are now placed in the orders Perissodactyla (horsse types,
tapirs & rhinos, odd-toed ungulates), Hyracoidea (Hyrax), Proboscidea
(elephants, mammoth, etc), Suina (pig, hippo), and Artiodactyla
(even-toed ungulates).Grace Fields
