Spiders

Explanation:

There are many bio luminescent organisms, or organisms that make their own light.

Many types of jellyfish create their own light, usually to scare away predators. Fireflies also create bioluminescence, creating their well known light that gives them their name. There are some species of bioluminescent fungi. They do this to deter predators and to attract insects that can aid in the process of dispersing spores.
