Featured in the Open Ocean Jellies poster, available at the Ocean Science Exhibit Center.
Info from poster: A siphonophore, which is closely related to the medusae. These animals are made up of multiple units, each specialized for a function like swimming, feeding, or reproduction. This "modular" construction allows some siphonophores to grow very large, over 100 feet long in the deep ocean. Although most siphonophores live below the surface, the Portuguese Man o' War is one that rests on the surface, suspended by a gas-filled float.

Physophora hydrostatica, a siphonophore, is made up of multiple units, each specialized for a function like swimming, feeding, or reproduction. This "modular" construction allows some siphonophores to grow very large––over 100 feet long in the deep ocean. This and other images taken by biologist Larry Madin are featured in the "Open Ocean Jellies" poster, available at the Ocean Science Exhibit Center.
