深海琵琶鱼如何利用生物发光在完全黑暗中捕食？

Deep-sea anglerfish live below 1,000 meters where sunlight cannot penetrate.
They possess a bioluminescent lure called an esca, which dangles from their head.
This light comes from symbiotic bacteria that live inside the esca and glow continuously.
The fish controls the light indirectly by adjusting blood flow to the lure tissue.
Prey animals mistake the glow for small prey or mating signals and swim closer.
Once near, the anglerfish opens its enormous mouth with needle-like teeth in milliseconds.
Females are much larger than males, and some males permanently fuse to females as parasitic mates.
Their eyes are highly sensitive to blue light—the only wavelength that travels far underwater.
This adaptation allows them to detect faint bioluminescent signals across several meters.
Scientists study their photophores to design low-power underwater sensors for robotics.
