The blackmouth catshark is a member of the catshark species that come from the family of Scyliorhinidae. They are found in the deep waters of the Atlantic Ocean.

Like their other relatives, these animals are predatory by nature. They are really beautiful to look at with a rather chic pattern on their back to the end of their tail.

The blackmouth catshark (Galeus melastomus) is quite skilled when it comes to preying for food. This fish has really good eyesight and electroreceptive systems that enable them to spot the slightest movement that occurs around them. Their eyes are trained to detect any bioluminescent prey around them.

Unlike other sharks that primarily use the sense of smell, these animals use other characteristics to fill their bellies. They might prey on aquatic animals together with other blackmouth catsharks.

However, the diet of this small shark is defined by decapods, bony fishes such as lanternfishes, little dragonfishes, bristlemouths, moras, and cephalopods.

Did you know...

 In 2019, fishers near the Mediterranean Sea in Italy, accidentally pulled a mutant from the depths. Once the researchers examined the mutant, they realized it was a blackmouth catshark.

They almost mistook it for an 'alien' as the fish had no external skin. Researchers had never seen an aquatic animal of that sort. The blackmouth catshark (Galeus melastomus) found was a young female and her age was approximately about three years old.

The size of this naked fish came up to about 1 ft (30.48 cm) long. The fish lacked teeth as well.

The sight was rather astounding to come across even though albinism was common in aquatic animals. The skin-less catshark had a belly full of food when it was found. It is not uncommon to find a mutant species, but to think that a catshark can exist without its skin is just mind-blowing!

Their eyes are trained to detect any bioluminescent prey around them. Unlike other sharks that primarily use the sense of smell, these animals use such characteristics to fill their bellies.

The spotted catshark is the largest catshark. Another interesting catshark is the false catshark.

How did the blackmouth catshark get its name?

The name, blackmouth catshark, is inspired by its small, wide arched mouth that is pitch black from the inside. They have 69-79 teeth in their upper and lower jaw through that they use to prey on other aquatic animals found in deep waters.

How is it different from other sharks?

The most distinctive feature of the blackmouth catshark (Galeus melastomus) is its aesthetic pattern. It has a brownish-gray colored skin with around 15-16 white blotches adding a form of definition. Its long slender body is no bigger than your childhood baseball bat.

The underside of its body is fairly bright in color compared to the rest of its body. Their dorsal fins and caudal fins are colored white at the tips. In a sense, you could say, for a scary catshark, this animal is quite beautiful.

Unlike other sharks that rely primarily on their sense of smell, this catshark mainly uses its sense of vision and electroreception to prey for food. Their horizontal oval-shaped eyes are extremely good at detecting any bioluminescent activity.

The blackmouth catshark (Galeus melastomus) is unique in its own way. It's a good thing that this species conservation status is at Least Concern.
