Description: The body of the Tire Track Eel is elongated with a long snout. Both the dorsal and anal fins are extended and joined to the caudal fin. Its base color is a tan to light brown. Along the entire length of its body, reaching vertically from its back to its belly, it is patterned with a series of irregular dark markings. These markings have a 'tire track' or 'zig zag' appearance which has been used as a common name. They often bury themselves during the day in the substrate, coming out at night to feed.

Sexual differences are unknown and it is almost impossible to identify the sexes, though a mature female may be more full bodied.
