Etymology: Myrophis: Greek, myros, -ou = male of morey eel + Greek, ophis = serpent (Ref. 45335). More on author: Lütken.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 0 - 100 m (Ref. 5951). Tropical
Western Atlantic: Bermuda and North Carolina (USA) to Brazil, including the Gulf of Mexico, the West Indies, and the coast of Central America. Also throughout Caribbean (Ref. 26938). Northwest Atlantic: Canada. Records from the eastern Atlantic need confirmation.

Morphology | Morphometrics
Pale brown, with a fine peppering of black spots on the back and sides of the body; ventral surface is light (Ref. 30499).
Inhabits seagrass beds from bays and mangroves to offshore reefs. Adults move to open sea to spawn. The species has considerable regenerative powers (Ref. 5521). Tidal creeks and brackish estuaries offshore to depths of 7 m (Ref. 26938). Reported from fresh water in Nicaragua, Costa Rica, and Mexico (Ref. 30499). Caught for bait fishery with use of ichthyotoxic plants (e.g. 'cunabi') along the north Brazilian coast (Ref. 34896).
