Sea Rocket-Marrus Orthocanna

Like a multi-stage rocket, this bizarre microscopic creature, Marrus orthocanna is made up of multiple repeated units, including tentacles and multiple stomachs. Never heard of a physonect siphonophore? That's what this is. It's something like a jellyfish, and is more closely related to the Portugese man o'war. One interesting thing about it: Like ants, a colony made up of many individuals has attributes resembling a single organism.
