The devil fish species get their name because of the fins called cephalic fins on their mouths which look like the devil’s horns. These large rays live in ocean water habitats. The devil fish (Mobula mobular) species was earlier confused with the manta rays (Manta birostris) species because Manta birostris and Mobula modular are closely related creatures. These fishes are one of the largest rays of marine life in the ocean. These creatures are also called giant devil rays.
The conservation status of this devil fish species is listed as Endangered. It has been an endangered species for over a decade and concerted efforts for their conservation are required. The devil fish is a magnificent creature of the sea.

What is a devil fish"s habitat?
A devil fish prefers to stay in shallow waters of the ocean of depth up to 164 ft (50 m), as opposed to manta rays, who prefer deep waters.

How do they reproduce?
The male devil fish chases female devil fish through the reefs to pursue them to mate. Not as much information as there is on manta rays has been recorded on the mating of the giant devil rays. The female devil fish is ovoviviparous. It means that one egg is fertilized and incubated in the womb. The egg then hatches, and a baby fish with small fins is hatched inside the womb itself. The baby stays in the womb; it absorbs proteins, vitamins, and nutrients from the uterine wall until it grows to a suitable size. After a year and a half, the baby giant devil ray is born. A baby of the devil fish is around 1 ft (30.5 cm) in length at the time of birth. The long incubation period is not helping the endangered species.
What is their conservation status?
The conservation status of the devil fish is Endangered. The population of these creatures is endangered because of the extensive fishing of giant devil ray done by the fisheries industry. Climate change and habitat loss are other reasons behind the endangered status of the giant devil ray species.
