Mjukstrålar i ryggfenan (totalt) : 26 - 30; Mjukstrålar i analfenan: 4. Distinguished by the lack of appendages on the trunk in the juveniles, head at no angle to the body, and color patterns (Ref. 48635).
Body shape (shape guide): eel-like.
Found on the continental shelf (Ref. 5316). Enters sheltered muddy estuaries where laying out in the open on the bottom (Ref. 48635). Most specimens from dredge and trawl collections (Ref. 5316). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Solitary on mud bottoms (Ref 90102).
