Rare bright orange shark discovered in Costa Rica

This fisherman was very shocked to catch the unusual shark

Have you ever seen a shark like this?

This amazing bright orange shark is so far the only one of its kind, found during a fishing trip near Tortuguero National Park in Costa Rica.

Its unusual colour is caused by something called xanthism, a condition which researchers say is extremely rare in fishes like sharks.

Publishing the pictures in the Marine Biology journal, scientists say that this is the first ever time that a shark of this colour has been found.

Xanthism is caused by pigments in the skin, which is something that all animals have that gives their skin a certain colour.

The condition happens when creatures have a loss of darker pigments, meaning that a yellow or orange colour comes through more strongly.

This shark is even more unique because it also has white eyes, which researchers say could mean it also has albinism.

This is another condition that leads to little or no production of a pigment called melanin, which can cause the colour of a creature's skin, hair and eyes to be white.
