Siphonophores

Siphonophores are a class of invertebrates belonging to the phyla Cnidaria, which means they are related to corals, hydroids, and true jellyfish. Although a siphonophore appears to be a single organism, it is actually a colony composed of many individual animals. The majority of siphonophores are long and thin, consisting mostly of a clear gelatinous material, but all siphonophores are predators, and use their many tentacles to capture crustaceans and small fish.
Recently, a team of researchers including MBARI’s Steven Haddock published a paper describing two new species of siphonophores using samples collected on the Western Flyer. These species of the genus Apolemia are abundant and conspicuous in Monterey Bay.
