Nettastoma syntresis

Nettastoma syntresis is an eel in the family Nettastomatidae (duckbill/witch eels). It was described by David G. Smith and James Erwin Böhlke in 1981. It is a marine, deep water-dwelling eel which is known from the western central Atlantic Ocean, including the Bahamas, Cuba, and the northeastern Gulf of Mexico. It dwells at a depth range of 0 to 641 m. Males can reach a maximum standard length of 55 cm.

The species epithet "syntresis" means "channel" in Greek, and is treated as a noun in apposition. It refers to several channels in which the species has been found, including the Santaren, Nicholas and Northwest Providence Channels.
