Notes

Large, deep-bodied eel-like shape. Large prominent lips and small rounded eyes. Large, rounded bulbous head. Smooth, scale-less appearance. Very round, large pectoral fins. Colors range from grey to white. Distinguished from other zoarcid morphospecies by large size, rounded head and pectoral fins.
