Swell sharks hunt at night for bony fish, molluscs, and crustaceans. [2] [3] They will eat prey that is dead or alive. [3] They feed either by sucking prey into their mouth or by waiting motionless on the sea floor with their mouth open, waiting to encounter prey. [2] [4] Swell sharks have also been known to look for food in lobster traps. [2]
Cephaloscyllium is a genus of catsharks, and part of the family Scyliorhinidae, commonly known as swellsharks because of their ability to inflate their bodies with water or air as a defense against predators. These sluggish, bottom-dwelling sharks are found widely in the tropical and temperate coastal waters of the Indian and Pacific Oceans ...
It feeds on small crustaceans, cephalopods, and fish. When threatened, it responds by rapidly taking in water or air to inflate its body, hence the name "swellshark". This shark is oviparous and females lay pairs of distinctively ridged egg capsules at 20- to 30-day intervals. The eggs hatch after 11–12 months.
The whitefin swellshark resides in a heavily fished region and while not a commercially targeted fish, are commonly captured as bycatch in trawls. [2] The Australian South East Trawl Fishery, which operates off New South Wales, over a third of this shark's range reported that its catch rate dropped over 30% between 1967–77 and 1996–97.
The entire body of a shark is a very efficient eating machine. Each organ has been fine-tuned for hunting and acquiring food. Sharks are built to feed: Here's why they are the ultimate eating machines
Voracious and opportunistic in feeding habits, the blotchy swellshark is known to consume numerous types of fishes and invertebrates, including an unusually high diversity of cartilaginous fishes. Like other Cephaloscyllium species, it is capable of rapidly inflating its body as a defense against predators.
