orange siphonophore


The physonect siphonophores are actually colonies of individuals, each specialized for different functions such as swimming, feeding and reproduction. Here, the lead animal of Marrus orthocanna is a gas- filled float, followed by more than a dozen swimming morphs, that trail dozens of tentacle-bearing individuals that snare prey for the colony.
