True or False. Manatees can replace old, worn-out teeth with new ones.?

Manatees, which are close relatives of elephants, can replace their molars, or cheek teeth, just like elephants can. Manatees do not have incisors or canines. Elephants cannot replace their other teeth. For example, if an elephant lost one or both of its tusk (which are incisors), they cannot be replaced.
