Orectolobus
Orectolobus is a genus of wobbegongs, a group of sharks belonging to the family Orectolobidae. These sharks are found in the Indo-Pacific region, inhabiting shallow coastal waters, reefs, and estuaries. The genus is characterized by its flattened, broad bodies, with distinctive skin folds and numerous barbels around the mouth. Wobbegongs are ambush predators, relying on camouflage and a quick bite to capture prey.
Common Names
The common names for Orectolobus species vary, but generally include "wobbegong" or "carpet shark". Some examples include:
- Spotted wobbegong (Orectolobus maculatus)
- Banded wobbegong (Orectolobus halei)
- Brown wobbegong (Orectolobus hutchinsi)
Characteristics
Orectolobus sharks share several distinctive characteristics:
- Flattened, broad bodies: Their bodies are adapted for lying camouflaged on the seabed.
- Skin folds: These folds, resembling wrinkles, further enhance camouflage.
- Numerous barbels: These sensory appendages around the mouth help them detect prey.
- Small, narrow eyes: Situated on the top of the head, they allow for peripheral vision while camouflaged.
- Large, gaping mouths: Armed with rows of sharp, pointed teeth, they deliver a quick, powerful bite.
Environments
Orectolobus species typically inhabit shallow coastal waters, ranging from sandy bottoms to coral reefs and rocky outcrops. They are often found in estuaries, where the mixing of freshwater and saltwater provides a diverse ecosystem. Some species can tolerate brackish water.
