Part B: Anglerfish Being ugly doesn't mean you can't be cool. Just ask the deep-sea anglerfish. It lives near the bottom of the ocean. The deep-sea anglerfish does not make its own light. Instead, it has glowing bacteria that live inside its lure. The bacteria get food and stay safe inside the anglerfish, and the anglerfish gets the glow from the bacteria. So, they are both happy. Probably one of the best-known glowing creatures, the deep-sea angler uses a lighted lure to attract its prey. The lure hangs near its mouth. It moves the lure to attract prey. When other fish see the small light, they think it's something they can eat. When they get close enough, the anglerfish eats them up with its giant mouth. The mouths of an anglerfish are so big and their bodies are so soft that they can eat prey up to two times their own size.
Part A: Vampire Squid Not many animals have a name as terrible as the vampire squid. You may think this is a terrible creature, but it's really not. The vampire squid is an animal that lives in the deep sea and makes light, or glows. It actually eats small creatures that float in the ocean. The vampire squid has lights on different parts of its body. It uses these lights to lure its prey. It also uses light to protect itself. Its body creates a glowing liquid that it squirts out to get away from predators: animals that are trying to eat it. While the predator is looking at the glowing liquid, the squid can get away.
Bristle Worms If you want to make friends, you have to know how to shine. Bristle worms do just that. They get their name from their many bristles, or hair-like body parts that look like little legs. There are over 10,000 different types of bristle worms in the oceans. They live in many ocean environments, from the open water to the deep sea. Bristle worms have been around for a very long time, over 505 million years. Many bristle worms glow. They swim near the surface of the water at certain times and start to glow. Not all of them glow in the same way. Some shine with a green glow, while others give off short flashes of light. For bristle worms, this light show allows the worms to communicate with each other.
