Breeding, wildlife status & population

Not much is known about the breeding cycle of this fish though it is likely that they mature between 13 and 17.

The wildlife status of the Antarctic toothfish has not been evaluated as yet.

This means that the population has not been found.


They migrate every 24 hours from the seafloor to mid-range during the night to feed on the crustaceans.


First and foremost; the Antarctic Toothfish has anti-freeze in its blood tissues so that its blood does not become all crystallised and then all the blood would freeze causing the animal to die.

Second; it has special chemicals in its eyes so that in the freezing cold water they still can see clearly.
