Antarctic Ice Fish (Notothenioid)
Notothenioid fishes (ice fishing) Antarctica have special abilities produce natural anticoagulant help them survive in the icy environment, which is facing extinction due to climate change. thanks antifreeze glycoprotein in notothenioid fish body that can survive the fish after the global glaciation, the global glaciation caused a large amount of creatures extinct 42 million years ago. Substance glycoprotein help ice fish have time and space to adapt to the changes of the new ecological environment. And ice fish time spawning fish and thrive most researchers determined that about 10 million years ago.
Along with the acquired antifreeze and the loss of the swim bladders, there are some more general adaptations that the Antarctic ice fish have acquired over the years such as lighter skeletons to increase neutral buoyancy, wider jaws for better hunting, and a more streamlined body shape to increase the speed and the hydrodynamics of the fish itself (Begemann 2010). These traits, one can infer, are for the sole purposes of survival. In order to get away from predators and also be able to catch prey, they would need to be more hydrodynamic. Therefore, the Antarctic ice fish experience these more general changes to increase efficiency and use the least amount of energy. This is more commonly known as the optimal foraging strategy.
Antarctic ice fishes have become one of the most intriguing and unique creatures in the Antarctic. Whether it’s the translucent skin, the absence of swim bladders or the presence of antifreeze inside the fish’s bodies, these Antarctic ice fish have become extremely adapted to their climate and habitat over time, enabling them to survive in below-zero waters.
The reason why i choice this article because Notothenioid ( IceFish) are weird and glycoprotein help them still live after the glaciations. Currently in the world there are about 100 different species of notothenioid fish but some of species are seriously threatened by them became the main food source of penguins, seals and toothed whales, a key factor pushing notothenioid species to the brink of extinction is a phenomenon of global climate change. Meanwhile, the South Pole is one of the areas most strongly affected from climate change phenomenon, typical temperatures in increasingly warmer water.
