Artist's reconstruction of D. magnicornis with conservative skin flaps attached to its tabular horns. Diplocaulus had a stocky, salamander-like body, but was relatively large, reaching up to 1 m (3.3 ft) in length.
The classic form consists of a Y-shaped frame, with two tubes or strips made from either a natural rubber or synthetic elastic material. These are attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the frame, while the other hand grasps the pocket and draws it back to the ...
A chameleon launching its tongue at its prey. Chameleons, frogs and some lungless salamanders have tongues that act like a tethered projectile.
