The opah,Lampris Guttatus,正在以最近发现的大部分身体温暖的能力来重写鱼类生物学规则。鱼类生物学家早就知道某些鱼类(例如金枪鱼)可以使身体的某些部位保持温暖,例如它们的眼睛和核心,但Opah是发现的第一批鱼类具有特殊适应的鱼类,使其能够保持身体温暖周围水的环境温度。
Well known as a large species of sportfish, the opah has long been suspected to be different from other deep water living predators. Instead of being a sluggish ambush predator, the opah is built for speed with a muscular body, large powerful fins, and large eyes that all come together to make it a swift and efficient hunter.
在深水中被温暖血液的能力使Opah和在海洋深处所有其他冷血动物的优势受其冷血性限制。流血使Opah采取行动和反应迅速,并且移动的速度比其他鱼更快。
What makes the opah so unique is how it generates heat, and how it retains it to keep as much of that warmth inside its body as possible. For starters, you may have noticed the cartoonishly round shape of the opah, which strikes a balance between being streamlined to move through the water while also reducing the surface of its body which is exposed to the cold water around it.
此外,月鱼通过拍打pector移动al fins really fast, instead of undulating its body. The large pectoral fins and deep pectoral muscles reminds us of a much smaller freshwater fish, the hatchetfish, which can flap its pectoral fins so fast as to fly out of the water over a distance to escape predators.
奥帕(Opah)的温水吸烟枪是其ill的独特形状,它使用反电流流动,以防止其血液失去过多的热量,从而使其必须呼吸。奥帕(Opah)对温暖血液寿命的特殊改编的结合使其可以使其大部分的身体高达5C,高于周围水的温度。
像许多事情一样,我们在学校被教导要成为黑白,关于自然的真相比我们被引起的相信要有趣得多。鱼may be more primitive than us but that doesn’t mean they have stopped evolving, and we gotta give props to the opah fish for pulling off a very important feature of mammals and birds that not even reptiles or amphibians have been able to reproduce – endothermy.
