Stylactaria [Stylactaria]

Description

Stylactaria is a genus of hydroids in the Hydractiniidae family, characterized by their small, delicate colonies that often form on algae and other marine plants. The colonies are made up of branching stems from which polyps protrude, serving various functions such as feeding and reproduction. Stylactaria species are notable for their elegant appearance and the intricate structure of their colonies. They contribute to the biodiversity of marine ecosystems by serving as both predators of small planktonic organisms and prey for larger marine animals.
