   Body Shape

   Look for a distinctly elongated, cylindrical, snake-like body. It lacks the flattened or compressed body typical of many other fish.

   Note the complete absence of pectoral and pelvic fins. The dorsal, caudal, and anal fins are fused into a continuous, low fin fold along the posterior body.

3. 3

   Scales

   The skin is smooth and scaleless, often covered in a protective layer of mucus.

4. 4

   Gill Openings

   Observe the small, slit-like gill openings located ventrally on the head, rather than the large opercular flaps seen in most fish.

5. 5

   Eyes
