Escolar

Escolar (Lepidocybium flavobrunneum) is a species of fish in the family Gempylidae. It is also known as the snake mackerel. This species is found in deep tropical and temperate waters around the world.

Description

Escolar can grow up to 2 meters (6.6 feet) in length and weigh as much as 45 kilograms (99 pounds). It has a dark brown to black coloration and a robust, elongated body. The skin of the escolar is smooth and lacks scales, which is a distinguishing feature among other members of the Gempylidae family.

Habitat

Escolar is typically found at depths ranging from 200 to 885 meters (656 to 2,904 feet). It inhabits the continental shelf and continental slope regions of the ocean. This species is known to be a solitary predator, feeding on other fish and squid.

Diet

The diet of escolar primarily consists of other fish and cephalopods, such as squid. It is an opportunistic feeder and uses its sharp teeth to capture and consume prey.

Commercial Importance

Escolar is often caught as bycatch in longline fishing operations targeting other species such as tuna and swordfish. It is marketed in some regions under various names, including "butterfish" and "white tuna." However, the consumption of escolar is controversial due to its high oil content, which can cause gastrointestinal distress in humans.

Health Concerns

The flesh of escolar contains a high level of wax esters, which are not easily digested by humans. Consumption of escolar can lead to a condition known as keriorrhea, characterized by oily diarrhea. Due to these health concerns, some countries have issued advisories or restrictions on the sale and consumption of escolar.

Regulations

In some regions, the sale of escolar is regulated or banned due to the potential health risks associated with its consumption. Consumers are advised to be cautious and to limit their intake of this fish.
