Notes

Large round, bulbous head with a tadpole-like body morphology. Reduced eyes. A variety of colormorphs exist ranging from beige to dark brown. May have lighter spots. Single dorsal contiguous with anal fin. Pelvic fins reduced to one ray each and below head. Distinguished from other ophidiids by the large rounded head.
