Porpita porpita—the blue button jelly —is a neustonic species mostly found in the tropics; that is, it floats right neat the surface of the water. The circular disc is made of chitin and filled with gas, allowing these jellies to float. The tentacles (zooids) radiating from the disc do all the feeding. (via Woods Hole Oceanographic Institution)

flower-shaped jelly - The deep ocean is home to hundreds of species with soft, jelly-like tissues. Many of these gelatinous animals are transparent, and many are beautiful. Siphonophores, such as the one pictured, are closely related to jellyfish. Such modular construction allows some deep-sea siphonophores to grow to more than 100 feet long.
