Feeding in Chioglossa lusitanica

Chioglossa lusitanica is found in Portugal and Spain and is the only species in its genus. The golden striped salamander is semi-aquatic but has no apparent aquatic specializations. Like Salamandrina and all the plethodontids, it has a very long tongue. The tongue works with the same basic mechanism as that of Salamandrina, but the tongue skeleton moves farther forward before and during flipping, so the tongue has greater reach. In this feeding, the salamander's tongue hits the plastic surface as well as the termite. The tongue is so sticky that the salamander pulls its whole body downward when it retracts its tongue. The movie is at 1000 fps, so the time between frames is only 1 ms.
