Siphonophore colony. Colonial grouping of siphonophores, a type of hydrozoa. These marine invertebrates live in colonies made up of a number of highly specialised individual organisms (zooids). Each type of zooid (both medusae and polyps) has a specific role to play and none can live without the other. Because of this, siphonophore colonies look like one large organism and can often be mistaken for jellyfish. Photographed in the western Pacific Ocean, in the Sea of Okhotsk.
