Macrotis means 'big-eared' (macro-+ ōt-'ear') in Greek, referring to the animal's large, long ears. [4] The genus name was first proposed as a subgeneric classification, which after a century of taxonomic confusion was eventually stabilised as the accepted name in a 1932 revision by Ellis Troughton. In reviewing the systematic arrangement of ...
Tusks are generally curved and have a smooth, continuous surface. The male narwhal's straight single helical tusk, which usually grows out from the left of the mouth, is an exception to the typical features of tusks described above. Continuous growth of tusks is enabled by formative tissues in the apical openings of the roots of the teeth. [2] [3]

The aardvark has a long, thin, snakelike, protruding tongue (as much as 30 centimetres (12 in) long) [6] and elaborate structures supporting a keen sense of smell. [30] The ears, which are very effective, [6] are disproportionately long, about 20–25 centimetres (7.9–9.8 in) long. [22] The eyes are small for its head, and consist only of ...
Manatees have four rows of teeth. There are 6 to 8 high-crowned, open-rooted molars located along each side of the upper and lower jaw giving a total of 24 to 32 flat, rough-textured teeth. Eating gritty vegetation abrades the teeth, particularly the enamel crown; however, research indicates that the enamel structure in manatee molars is weak.
