Fishermen catch rare orange shark.

Rare orange sharks spotted off the coast of Costa Rica have astonished fishermen and scientists alike, revealing many fascinating mysteries of the deep ocean.

A nearly 2-meter-long orange shark was caught by a fisherman during a sport fishing trip off the coast of Costa Rica. The shark's "unusual" coloration has piqued the curiosity of many.

According to experts, the orange shark exhibits characteristics typical of xanthism – a rare pigmentation condition that causes yellow or golden discoloration of an animal's skin, scales, or fur.

Although xanthism has been observed in some fish species, it has never been recorded in cartilaginous fish, including sharks, rays, and stingrays, in the Caribbean.

Besides its unusual orange color, the shark also has striking white eyes. This indicates that the animal has albinism. Scientists believe that it is extremely rare for this shark to survive to adulthood with both abnormal pigmentation conditions.

Based on the shark's size, researchers from the Federal University of Rio Grande concluded that having two abnormal pigmentation conditions did not appear to affect its chances of survival.

Typically, albino animals and those with xanthism are easily targeted by predators due to their strikingly bright coloration.

At the same time, this condition also makes them more sensitive to sunlight and reduces their ability to find a mate. Photo: Parismina Domuss Dei/Facebook.
