As we are well into Angel Shark season here in Tenerife I thought I would write about them… They are interesting, weird looking Shark and sadly they are an endangered species… in some locations even extinct now.. More on this later.. On this Blog I will talk about angel shark diet, habitat, reproduction, species, and physical appearance.
Angel sharks belong to the family of Squatinidae. These sharks have stretched-out bodies along with the wide pectoral fins that largely resembles with the rays. There are around 16 species that fall under the genus Squatina in the same family. The angel sharks inhabit all throughout the tropical and temperate waters of the world. One of these species is known to exist in deep waters at a depth of about 1,200m.
The angel sharks are not considered to be dangerous to humans but one should not approach them as they have a powerful bite force and pointed teeth. Angel sharks are typically termed as ‘Bottom-dwellers.

* The rear part of angel sharks resembles more like typical sharks.
* They have their eyes and spiracles right on top with five gills located below.
* The length of angel sharks measure around 1.5 meters.
* These shark species are very fond of eating crustaceans, mollusks, and fish.
* The angel sharks are ovoviviparous and they give birth to 13 – 20 pups.
* These fish are harmless but the respect should be given as they can pose danger if provoked.
* Back in 1980, the angel sharks provide an important food source especially for fisheries.
* The largest Angel Shark in our waters measures around 152 cm with the maximum age lived of 30 years.
* The males become mature at 8 years, with the length measuring at 75 – 80 cm.
* The females reach the maturity age after 13 years, with the length of 90 – 100 cm.
* There are white markings on the angel shark’s body coupled with the reddish-brown color. They display different colors that ranges from bright brown to the light grey. This much variation in the colors enables these species to be camouflaged themselves.
* They have sharp teeth with the upper jaw embedded with lots of teeth and the lower jaw with even more teeth.
What do angel sharks eat?
They tend to camouflage themselves in sand patches, rocky areas or patch reefs during daytime. Some of the most common angel sharks preys include squids, small fish, octopus, and crustaceans. These species are sit-and-wait predators. These fish often prey on mollusks, croakers, hake, halibut, peppered shark, corbina, blacksmith, flatfish, and other kinds of bony fishes. They seldom take on invertebrates other than those mentioned above.
Where do angel sharks live?
The angel sharks have an extensive distribution around the globe with species inhabiting across the tropical waters to the cold northern waters, and are often found in deep waters. Most of these species are active during night; they are considered to be bottom-dwellers and are known to prey on species that are hidden under the sand with the help of their trap-like jaws. These species are best known to primarily feed on small bottom fishes.
according to the available data the mating of these species begins in summer season. The young sharks tend to develop inside the female mothers. The gestation period lasts for about 10 months and the usual births take place in the months of June and March. The females litter 13– 20 pups. These pups are 25 cm long at birth.
