Whoa, what's that? It's so colorful! The DEEPEND scientists tell me that this is a siphonophore. Siphonophores belong to the animal group that includes corals and jellyfish. This group is called Cnidaria. Siphonophores are colonial animals. Colonial animals are multiple individuals that are connected and work together. Siphonophores can grow to be 40–50 meters long. That's about the length of a Blue Whale! Siphonophores feel gelatinous. This means they feel like jello! My favorite jello flavor is cherry, how about you?
Siphonophores are active predators, just like the heteropods we talked about last time. They hunt small fish and crustaceans. When they get close enough, siphonophores use their tentacles to capture and reel in the prey. Some individuals of the colony are responsible for motions that help to move and orientate towards prey while others catch the prey or digest it. Each individual of a siphonophore has its own role to play.
Siphonophores bioluminesce blue or green when they feel threatened. Remember how the Dragonfish uses bioluminescence to attract prey? Well, siphonophores use bioluminescence to try to scare predators.
That's all for today. See you next time!
