Colombian shark

The Colombian shark is also known as tete catfish, smooth catfish and black cuminate; although it is not a shark but a demersal fish. Its scientific name is Ariopsis seemanni and it is part of the Ariidae family.

Where does the Colombian shark live?

This animal is native to the southeastern and central western Pacific Ocean, and can be found in the waters of Ecuador, Guatemala, Panama, Honduras, Peru, Mexico, Nicaragua, Costa Rica, El Salvador and Colombia; being very abundant in the latter country, hence the reason for its name.

In addition, its swimming limits are quite small, since it goes to a maximum depth of 20 meters, usually staying on coastal waters and estuaries, with frequent variations.

It is important to note that it is listed as a freshwater species, however, it can be incorporated into salt water as it grows .

In the event that they are kept in captivity, an aquarium or pond that exceeds 75 gallons of water will be needed, so that they can perform their fast swims. In addition, this must incorporate rocks, plants, trunks and other elements that simulate their habitat.

Characteristics of the Colombian shark

Its small size makes it ideal for keeping in aquariums and ponds , since the males reach an average of 35 centimeters in length and specimens of up to a little over 50 centimeters in length have been recorded.

One of the most striking features is its whiskers, as some of them are located in the lower part of its snout and the others just below the nose but more upright.

Meanwhile, the color of its skin is quite striking because it is between silver and gold, being lighter towards the ventral area.

Is the Colombian shark in danger of extinction?

Fortunately, the Colombian shark is out of danger , and has been added to the category of "least concern"; this according to the lists published in 2010 by the International Union for Conservation of Nature.

And it is that until now there are no known considerable threats that could affect their subsistence. Although some commercial fisheries tend to catch it, but its wide distribution keeps it safe.

Conservation of the Colombian shark

Although it is not in danger of extinction, there are several areas that are protected in the eastern Pacific , and that function as a refuge for some of its subpopulations.

Curiosities of the Colombian shark

• Although it is born in fresh water, it can survive salt water as it grows.
