The still photos below show the morphology of the tongue and the extent of protraction. The first photo clearly shows the outline of the jointed tongue skeleton.
Pseudotriton ruber, the Red Salamander, is a hemidactyliine plethodontid, like Eurycea, and possesses a free projectile tongue that is protracted here in less than 11 milliseconds. This salamander usually lunges forward during prey capture, as during this capture of a cricket. The background grid is 1 cm (with a smaller 2 mm grid). This species is found in the eastern North America in springs and seeps, and can be seen roaming on rainy nights.
