Ampullae of Lorenzini are the tiny pores located on a shark's head. They are special sensing organs called electroreceptors which can pick up the electrical fields given off by heartbeats and muscle movement. Sharks have rows of teeth that can allow a new tooth to move in to replace one that may be lost.
The V-shaped tail indicates that this is a very fast-swimming fish. This fish was caught off the pier at Navarre Beach.
