Certain species living chiefly on ants and termites are consideredbelow. Myrmecophagous or Ant Eating Adaptations Several groups of animals have more or less independently becomespecialized for feeding upon ants or the somewhat similar termites. Thishas involved the development of strong digging claws to open up thenests, a long tongue for securing the ants, a lengthened skull for the. The giant ant eater has lost all its teeth and its skull is elongated to house the long sticky tongue housing of such a tongue, and has resulted in the reduction or loss ofteeth. Examples are the giant anteater (50), the pangolin (17), the aardvark (58), marsupial anteater (4), and the sloth bear which may be seenin the Hall of South Asiatic Alamma^. The reader is referred to page 20of this manual for notes on highly developed ant eating specializationsof the manis. Plankton Eating Adaptations The whale-bone whales (Mysticeti, 26) are the only mammalsequipped to feed on the minute animal life of the sea (plankton). Theyhave lost all teeth but have developed great fringed, horny plates withwhich they may strain out these minute animals from the sea water asthey swim along with mouth open. The gullets of these largest of allwhales are very small and suited only to swallowing of small swallow a creature the size of a man would be an impossible feat. Herbivorou
