Channichthyidae

Chionodraco hamatus

Crocodile ( Channichthyidae (Size: channe, it - = anchovy, ichthys = fish) ) only live in the Southern Ocean, on the shelf of Antarctica and southern South America.

Features

There are 25-72 cm long predatory fish, which have a large, spiny head and a flattened, pike -like snout. The mouth is not vorstülpbar (not protraktil ). The soft, gelatinous body is scaleless. Your gill membranes are grown together. The pelvic fins are wide or long. Crocodile have 22 to 31 vertebrae. Your ribs are not ossified.

Your blood and the gills are nearly colorless. They lack the red blood cells, and thus hemoglobin, the muscle lacks the myoglobin. The breathing oxygen is physically bound in blood plasma. Survival is assured by the extremely cold, very oxygen-rich water, additional skin breathing and a very large volume of blood.
