A golden shark was caught in Costa Rica (4 photos)

Fishermen off the coast of Costa Rica caught a giant "goldfish" - a shark with a rare mutation that turned its skin orange.





The nurse shark (Ginglymostoma cirratum) was not immediately recognizable; they are usually gray-brown. The rare color appeared due to xanthism - an excess of pigment that colors them in golden tones.



This is the first documented case of xanthism in cartilaginous fish. And this 2-meter shark also had white eyes, and usually they are black. This is another mutation - albinism





. In addition to studying how this became possible, scientists are interested in how the shark was able to survive with such coloring, how was it able to camouflage itself?
