WebAntarctic notothenioid fish avoid freezing in their perpetually icy environment because of an antifreeze protein that circulates in their blood. This evolutionary adaptation has allowed the Notothenioidei suborder to rise to dominance in the freezing Southern Ocean. It is said that all proteins function by binding to To what ligand do you WebJun 1, 2015 · Physiologists had long recognized that, because marine teleost fish are freeze avoiding and hypo-osmoregulators, with body fluid equilibrium freezing/melting points (eqFMP) of –0.6 to –0.9°C, they should be susceptible to lethal freezing in ice-laden seawater at ∼–1.9°C, especially when in contact with ice.
