What is siphon animal?

As an AI language model, I cannot find any particular information about a siphon animal. Siphon, on the other hand, refers to a tube-like structure used for drawing fluid from a container to another place which is usually at a lower level. Some animals have siphons such as some mollusks and crustaceans which use their siphons for locomotion, feeding, or breathing underwater. One of such examples is the siphonophores which are a group of predatory marine animals that colonize and drift in the open ocean.
