Scale type

placoid

Mouth position

subterminal

Distinctive features

Distinctive leopard-like spot pattern covering the entire body and fins., Two dorsal fins, with the first dorsal fin originating behind the pelvic fin origin., Prominent nasal barbels., Slender body with a relatively short, blunt snout.

Dorsal fin

Two relatively small dorsal fins, both located far back on the body. The first dorsal fin originates behind the pelvic fin origin, and the second dorsal fin is slightly smaller than the first.

Tail fin

Heterocercal caudal fin, typical of sharks, with a longer upper lobe and a less developed lower lobe.

Identification Tips

1. 1

   Spot Pattern

   The most distinguishing feature is the dense, irregular pattern of dark brown to black spots on a lighter background, resembling a leopard's coat. This pattern covers the entire body and fins.

2. 2

   Dorsal Fin Position

   Note the position of the first dorsal fin, which originates behind the pelvic fin origin. This helps differentiate it from some other catshark species.

3. 3

   Nasal Barbels

   Presence of prominent nasal barbels, which are sensory appendages near the nostrils.

4. 4

   Body Shape

   Its slender, elongated body is characteristic of catsharks, allowing it to maneuver through complex benthic habitats.
