Bioluminescence in Marine Life

Bioluminescence is the emission of light by living organisms, a phenomenon seen in many marine species and some land species, such as fireflies. This natural light production results from a chemical reaction involving luciferase and luciferins, the energy molecule ATP, and oxygen. The essential light-emitting components--the luciferins and luciferases- are specific for different organisms, and the color of the light produced might also vary, with blue-green being common in oceanic organisms.





Marine organisms use bioluminescence for various purposes, including attracting prey, deterring predators, and communicating. For example, certain species of jellyfish emit light when threatened, creating dazzling display to confuse predators. Deep-sea fish utilize bioluminescence to lure prey. In the same way moths are attracted to light, many sea organisms are attracted to bioluminescent glows and thus end up within reach of a hungry predator.





Researchers are fascinated by bioluminescence for its potential applications. The study of bioluminescent organisms has led to advances in medical imaging.Researchers can use luciferin to highlight diseased human cells and determine how effectively a drug has worked against them. Scientists are also exploring how bioluminescent proteins can be used to track the movement of cells within the human body.

1、明确题干核心要求 - 题干需要找到的是“生物发光用于躲避捕食者”的句子,核心逻辑是 “发光行为 → 实现躲避捕食者的目的”。 2、逐句分析第二段内容: - A:是总述海洋生物发光的三类用途(吸引猎物、威慑捕食者、交流),属于概括性表述,没有具体说明 “如何躲避”。 - B:以水母为例,明确指出其 “受到威胁时发光,制造炫丽景象迷惑捕食者”,这是具体的躲避捕食者的行为机制,完全匹配题干要求。 - C:讲深海鱼用发光引诱猎物,和 “躲避捕食者” 无关。 - D:说明其他生物被发光吸引而成为捕食者的猎物,是发光在 “捕食” 环节的作用,而非 “躲避”。
