Siphonophores - The longest animals on the planet
Cousins of corals, siphonophores are colonies of specialized individuals called zoids. Some catch and digest their prey, others swim, or lay eggs or sperm.

Embryos and larvae
Drifting in the currents, embryos and larvae perpetuate the species and are food for multitudes.
This video describes how to perform the Ludion experiment and explains the physical processes involved.
