Natural History

A fanfin anglerfish's glowing lure attracts fishes and other deep sea animals. For some animals, an anglerfish's light is a fatal attraction. For others, it signals a welcome feast. How does an anglerfish light its lure? It doesn't, exactly—special light-producing bacteria live inside the lure.

We know the photo above is a female because this species has parasitic males that are much smaller than the female.


The deep sea may seem remote, but what we send down will eventually cycle back up into our lives. Deep-sea animals are part of a thriving ecosystem. Our trash and chemicals may harm them if we are careless with our waste.
