As Shark Week continues to float on here in the US, we think it’s the perfect time to shine the spotlight on some of the strangest-looking sharks found on Earth. We all know what the great white shark looks like but have you seen a shark with an ‘executioner’ style hood over its head or one with a beard? Read on to see how many of these bizarre sharks are new to you!

 10. Trendy trim

With a chic patterning of splotches over its body, the leopard shark roams the ocean in the day and night. Despite the fear that all sharks are dangerous, the leopard shark is actually harmless to man and even approachable when it lounges on the sea floor during the day.

 9.  An immense encounter

We think this shark merits an appearance on this list just for its sheer size. The largest fish in the sea, the whale shark can weigh up to 13 tons. Perhaps ironically, the biggest fish in the world feeds primarily on some of the smallest organisms, tiny planktonic organisms.

8.  Hard-headed

The blunt snout of this species along with its large eyes makes the kitefin shark a perfect addition to our list. The kitefin shark is uniquely ovoviviparous meaning it gives birth to live young instead of laying eggs like most other fish species.

7. Hooded hider

With a black mask over its head and snout, the hooded carpet shark is said to resemble an eerie ‘executioner’s hood’. The addition of white spots that cover most of its body helps this species to blend into surrounding coral until this nocturnal shark comes to life at night.

6. Wide-eyed wonder

Check out the blinders on this fish! The crocodile shark is a small slender shark known for its short head and large eyes likely used to hunt effectively at night. Following its prey towards the water surface at night and away during the day, the crocodile shark is an active hunter which enjoys a wide variety of prey including squid, fish, and shrimp.

5. See a saw

Aptly named, the green sawfish has an elongated snout with over 23 pairs of teeth.  By using this impeccable nozzle, the green sawfish is able to feed on slow-moving fish by clubbing at them with a side of its saw. Cleverly, the green sawfish uses its saw to act as a shovel-like instrument to rake out crustaceans.

4. Face of an angel

Sometimes mistaken for a large ray due to its appearance, the angel shark has a remarkably flat body and well-placed eyes on the top of its head that are perfect for ambush-style predation. The angel shark is Critically Endangered, likely due to its prevalence in by-catch – the accidental capture of species through standard fishing practices such as trawling. Sadly, this species has been declared extinct in the North Sea.

3. Mega mouth

As the second largest fish in the sea, the basking shark is one to impress. Perhaps a good kisser, the basking shark uses its three-foot-wide mouth to filter feed while it ‘basks’. Not too interested in the social scene, the solitary basking shark is thought to hibernate in deep water.

2. Ancient allure

The frilled shark is one of the most primitive species of living shark. Having perfected its look to have a lizard-like, blunt-ended snout and a very large mouth, the frilled shark possesses an unconventional beauty. Living primarily in the deep-water darkness, this three-foot-long and mysterious beast has had few observations made in its natural environment.

1. Camouflaged charmer

Literally meaning ‘well fringed nose with shaggy beard’, the tasselled wobbegong is an exceedingly unusual looking shark. With its branching skin flaps and a lofty lattice-like ‘beard’ the wobbegong’s bristles provide it with a sagacious camouflage and overall appearance. We challenge you to find a weirder-looking shark on ARKive!

Angel shark (Squatina squatina)

Species: Angel shark (Squatina squatina)

Status: Critically Endangered (CR)

Interesting Fact: With its flat body and large pectoral fins, the angel shark more closely resembles a large ray than a shark.

The angel shark is a large, stocky fish with strong jaws and sharp, needle-like teeth. An ambush predator, it spends the day lying buried in mud or sand with just its eyes protruding, and bursts out with impressive speed to catch fish, crustaceans and molluscs. Female angel sharks give birth to up to 25 pups after a gestation period of 8 to 10 months. The angel shark historically occurred from Norway to North Africa, the Canary Islands and the Mediterranean and Black Seas, but it has now vanished from many parts of its former range.

Although the angel shark is not a major target of fisheries, its habit of lying on the ocean bottom makes it vulnerable to becoming bycatch in trawl fisheries. As a result, its populations have undergone a dramatic decline. Like other Squatina species, the angel shark is protected within three Balearic Islands marine reserves, where fishing for these sharks is banned. However, more research is needed to better understand the status of the angel shark across its range, so that appropriate conservation measures can be put in place to protect it.
