The Ocellated Ice Fish, a creature that lives in the freezing Antarctic Ocean, has totally transparent blood.

The odd fish was captured by a Japanese fishermen in 2011, who gave it to the Tokyo Sea Life Park.

Tokyo Sea Life Park officials recently told AFP that the fish lacks hemoglobin, a protein possessed by every other animal with bones.

Hemoglobin makes blood red and carries oxygen in the body. The Ocellated Ice Fish has no scales either, reports

The Tokyo Sea Life Park is the only facility that has the species in captivity.

"Luckily, we have a male and a female, and they spawned in January," said Satoshi Tada, of the Tokyo Sea Life Park.

Scientists believe the Ocellated Ice Fish lives without hemoglobin because it has a large heart and uses blood plasma to circulate oxygen around its body.
