Identification Tips

1. 1

   Body Shape

   Look for a very slender, elongated body that is almost stick-like, covered in bony rings rather than scales.

2. 2

   Snout

   Observe the distinctive long, tubular snout with a small, upward-pointing mouth at the tip.

3. 3

   Coloration

   Note the cryptic coloration, which usually matches the surrounding vegetation (greens, browns, reds, mottled patterns).

4. 4

   Fins

   Identify the single dorsal fin, small pectoral fins, and a small, rounded caudal fin. The absence of pelvic fins is also a key characteristic.
