What characteristic describes the lower jaw teeth of the viper dogfish?
Answer
They are long, needle-like, and sometimes hinged
The viper dogfish is famous for its specialized dentition, particularly the lower jaw teeth. These teeth are disproportionately long, needle-like, and slender. A unique feature is that they are sometimes hinged or movable, allowing them to protrude beyond the upper jaw even when the mouth is closed. This dental arrangement is perfectly adapted for grasping and securing slippery, soft-bodied prey like squid and small fish.
