Antifreeze glycoproteins were first discovered in Antarctic notothenioid fish.

Many Antarctic fish species produce antifreeze glycoproteins that prevent ice crystal formation in subzero waters. These fish form a crucial part of the Southern Ocean food web that sustains Mesonychoteuthis hamiltoni.

By preying on cold-adapted fish capable of surviving extreme temperatures, the colossal squid taps into an ecosystem stabilized by unique biochemical adaptations.

This indirect dependency shows how evolutionary innovations at lower trophic levels ripple upward to support some of the ocean's largest invertebrate predators.
