How to Identify Wobbegong

To identify Wobbegong (Orectolobidae), look at these key features.

Physical Characteristics

Body shape

flat

Coloration

Highly variable, typically mottled patterns of brown, yellow, grey, and black, often resembling the seafloor or rocky reefs. This camouflage is crucial for their ambush predation strategy.

Scale type

placoid

Mouth position

terminal

Distinctive features

Flattened body and head, Broad, flattened head with a wide mouth, Numerous dermal lobes, tassels, and branched dermal flaps around the mouth and along the sides of the head, forming a 'beard-like' fringe, Ornate, cryptic coloration and patterns that mimic their benthic environment, Two dorsal fins located far back on the body, close to the caudal fin, Anal fin present

Dorsal fin

Two dorsal fins, relatively small and positioned far back on the body, with the first dorsal fin originating over or behind the pelvic fin origin.

Tail fin

Caudal fin is relatively short, often with a distinct subterminal notch.

Pectoral fin

Large, broad, and paddle-like pectoral fins, used for resting on the substrate.

Distinctive fins

Pelvic fins are also large and positioned anterior to the dorsal fins. Anal fin is present and typically small.

Identification Tips

1. 1

   Body Shape and Coloration

   Look for a flattened body, broad head, and intricate, mottled patterns that blend seamlessly with rocky or sandy seafloors. The patterns are highly species-specific.

2. 2

   Dermal Lobes and Tassels

   The most distinguishing feature is the fringe of dermal lobes and branched dermal flaps around the mouth and along the sides of the head, resembling a 'shaggy beard'. The arrangement and complexity of these appendages vary between species.

3. 3

   Dorsal Fin Position

   Note the two dorsal fins positioned far back on the body, close to the caudal fin. This is characteristic of the family.

4. 4

   Anal Fin

   The presence of an anal fin helps distinguish them from some other shark groups.
