Stephalia [Stephalia]
Description
Stephalia is a genus of siphonophores that exhibit complex colonial organization similar to other members of the Physophoridae family. These organisms are characterized by their elongated, transparent bodies with distinct sections for feeding, reproduction, and movement. The colonies are supported by a gas-filled float, which helps maintain buoyancy. Stephalia species are adapted to life in the open ocean, capturing prey with their tentacles equipped with stinging cells.
