Ever pondered which shark species has the most unique appearance? The tasseled wobbegong shark is unquestionably a strong contender. These creatures, which are also known as carpet sharks, have unusually flattened appearances as a result of the distinctive, branching lobes that emerge from their heads. Although these sharks were initially documented in 1867, nothing is known about them, thus they continue to be a mystery.
a wobbegong with tails. Without a doubt, don’t step on it! Update: It appears that this is an anglerfish in the Lophiidae family and not a wobbegong. However, you still shouldn’t stomp on it!
The tasselled wobbegong (Eucrossorhinus dasypogon) is a species of carpet shark in the family Orectolobidae that inhabits the shallow coral reefs off northern Australia, New Guinea, and the adjacent islands. Reaching 1.8 m (5.9 ft) in length, this species has a broad and flattened body and head, but its most distinctive trait is a fringe of branching dermal flaps around its head, which extends onto its chin that enable it to camouflage itself against the coral reef environment, in which it lives.
During the day, the solitary tasselled wobbegong can generally be found lying inside caves or under ledges with its tail curled up, but when the night comes, it emerges and actively forages for food – even for humans, if the opportunity arises. They have been reported to bite and kill people even when unprovoked, with most attacks probably resulting from people accidentally disturbing them or being misperceived as prey.
The tasselled wobbegong is considered the most specialized member of its family. Its ornate coloration and complex outlook grants it excellent camouflage, while it is probably a slower swimmer than related species. But that by no way means a disadvantage for this guy.
While these animals are solitary and individual sharks have a small home range, containing several preferred resting spots that are used repeatedly, this species becomes more active at night, swimming onto the reef to hunt.
Its enormous mouth allows even sizeable prey to be swallowed, with one documented case of a 1.3 m (4.3 ft) long individual consuming a 1.0 m (3.3 ft) long brownbanded bamboo shark. Although the carpet shark is most active at night, it is an opportunistic ambush predator during daytime, preying upon schooling nocturnal fish such as soldierfish and squirrelfish, and sweepers that often shelter in the same cave.
Also, tiny fish and crustaceans have been seen settling atop the resting wobbegong’s head, attracting larger fish that are in turn attacked by the wobbegong.
In fact, observations of these animals in captivity have further revealed that this species seems to engage in an active luring behavior. And a really special one, for that matter. When the tasselled wobbegong perceives food nearby, it begins to slowly wave its tail back and forth, which makes its caudal fin resemble a small fish, complete with a dark eyespot at the base. And since the shark typically rests with its head elevated, it is situated within easy distance of any prey drawn by that curious tail. Even humans.
Yupp, wobbegongs have several records of attacks on people that were apparently unprovoked, and the tasselled wobbegong has a reputation for even more aggressive behavior than related species. Australian biologist Gilbert Whitley even wrote in 1940 that it “attacks and generally kills the natives” of Papua New Guinea.
And while it’s unclear whether Whitley’s claim held any truth, this species is certainly capable of inflicting severe wounds on humans. That said, the tasselled wobbegong is also an ecotourism attraction and many divers have approached it without incident.
