Caption: The development of antifreeze glycoproteins by notothenioids, a fish family that adapted to newly formed polar conditions in the Antarctic millions of years ago, is an evolutionary success story. The three species of fish are an example of the diversity this lineage achieved when it expanded into niches left by fish decimated by cold water environment. Now the same fish are endangered by warming of the Antarctic seas (in order: Chaenodraco wilsoni (common name: spiny icefish); Trematomus newnesi (common name: dusky rockcod); Vomeridens infuscipinnis (common name: antarctic dragonfish).
