...well, actually, in a way zoons (or zoa) are exactly that. If on a small scale.
A zoon is a colony of animals which live stuck together, like corals or sea pickles (sea pickles are stuck together with jelly). Siphonophorae are zoons, too, but being colonies of jelly fish they're more or less all jelly.
Here's a young sea pickle:

Word To Use Today: zoon. Sadly, you say this ZOH-on, not zoooon. It comes from the Greek word zōē, which means life.
