Lingual luring

Macrochelys temminckii luring

Lingual luring is a form of aggressive mimicry in which a predator (typically a snake or turtle) uses its tongue to fool potential prey into approaching close to what appears to be a small wriggling worm.

Lingual lures are very well developed in young alligator snapping turtles which wait underwater with their mouths open. The tongue is wriggled like a worm and fishes attracted to it are captured by a rapid snapping of the mouth. [1] [2]

Lingual luring has also been noted in some species of snakes including the garter snake Thamnophis atratus [3] [4] and species of Nerodia (including N. sipedon, N. clarkii and N. rhombifer) – here the luring is initiated by flicking the surface of water with their tongue to attract fish. [5] Similar behaviour has been reported in the snowy egret (Egretta thula) which uses tongue flicking when foraging. [6] [7] The puff adder Bitis arietans uses its tongue which is loosely wriggled like a worm to attract amphibian prey. The puff adder also uses its tail as a lure (caudal luring). [8]
