The Greater Bulldog Bat or Fisherman Bat is a type of fishing bat native to South America. The bats use echolocation to detect waterripples made by the fish upon which they prey, then use sharp claws to catch and cling to the fish.
The parallel is with bats and echolocation (or biosonar).
Bats are traditionally grouped with the tree shrews (Scandentia), colugos (Dermoptera), and the primates in superorder Archonta because of the similarities between Megachiroptera and these mammals.
Chinese lore claims the bat is a symbol of longevity and happiness, and is similarly lucky in Poland and geographical Macedonia and among the Kwakiutl and Arabs.
