Researchers at the Portuguese Institute of the Sea and Atmosphere (IPMA) and the Center for Marine Sciences (CCMAR) have identified a species of snake shark, which also lives in the Madeira. The capture of this animal was carried out by a fishing vessel from the Algarve. This is a very rare catch due to the fact that this species lives at great depths.
In August of this year, during a boarding, on the coast of the Algarve, on board a commercial trawler, researchers from the IPMA and CCMAR, recorded the capture of a shark with unusual characteristics. The report was made under the MINOUW project – ‘Initiative to minimise catches of unwanted catches in European fisheries’.
In the information now released by the Institute of the Sea and the Atmosphere can be verified that the species is also present in the seas of Madeira.
The researchers note that the fish is “a male of the snake-shark (Latin name, Chlamydoselachus anguineus), about 1.5 meters tall. This shark, a true ‘living fossil’, has a long, slender body and a snake-like head. It also presents a very particular dentition, its biology and ecology little known “.
The species is distributed “throughout the Atlantic, from the Norwegian coast, through Scottish waters, from Galicia, the Azores, Madeira and the Canary Islands, down the African coast to the Indian Ocean, reaching also Japan, Australia and New Zealand , is not very often captured because of the depths to which it lives. This specimen was captured at 700 meters depth. Taken from RTPM
