Moray eel

Moray eels, or Muraenidae, are a cosmopolitan family of eels. The approximately 200 species in 15 genera are almost exclusively marine, but several species are regularly seen in brackish water, and a very few are found in fresh water.

The moray's rear-hooked teeth and primitive but strong bite mechanism also makes bites on humans more severe, as the eel cannot release its grip, even in death, and must be manually pried off. While the majority are not believed to be venomous, circumstantial evidence suggests a few species may be."
