Question

How adaptation is helpful in the survival of antarctic fish thematomus which can remain active even in extremely cold sea water in biology 2?

Answer 1

An iceberg drifts in the Southern Ocean, where water temperatures would be colder than the freezing point of fish blood, were it not for special antifreeze proteins. The frigid waters of the Antarctic Ocean should be cold enough to freeze fish blood. A natural antifreeze however, keeps the fish blood flowing.
