Fluorescent fish and other animals other than corals have beenmaking headlines过去几年。列表中最显着的包容之一荧光鱼是荧光鲨鱼,最近的研究可能首先嘲笑了为什么鲨鱼荧光。
复杂蛋白质的荧光是一个简单的怪癖, interacting with light to generate nearly perfect re-emission at a certain wavelength. Since fluorescence is found in all kinds of animals who live in the absence of light, it is believed that for many living things, fluorescence is an accident, and not synthesized for a specific purpose.
It seems that fluorescence in sharks might actually serve a real function, especially in benthic sharks whose normal color pattern is one of very effective camouflage. With our excellent multicolor vision and depth perception, it is extremely difficult for us to find cryptic fish hiding in the benthos so imagine how hard this could be for a small benthic shark looking for a mate.
拳头认为Shakrs仅在黑白中看到,但事实证明,底栖物种的视野,例如肿胀的鲨鱼和连锁猫s,经过专门调整以感知荧光光谱中的光。研究生物荧光鲨鱼的研究人员发现,存在单个视觉色素,该色素在484纳米的峰值上响应光,与它们发出的荧光绿色整齐地重叠。
在一种物种中,链条catsharks发现,在荧光灯下的女性中,链条链接模式比男性更为明显,这是有道理的,因为雄性寻求雌性的繁殖。此外,发现荧光在软骨鱼中至少进化了三次,使科学家们相信这必须是鲨鱼生物学的重要功能。
膨胀和连锁猫需要冷水是一件好事,因为否则,它们的真棒荧光图案看上去像是坐在迪斯科舞台礁坦克的沙床上。[[科学报告这是给予的
