Genus
Common name: Sea Squirts
Scientific name: Polycarpa
Polycarpa is a genus of ascidian tunicates commonly known as sea squirts. These sessile creatures are notable for their tough, flexible outer tunic and their ability to filter feed by drawing water through siphons. They are often found attached to substrates in reef environments and can add a unique element to the biodiversity of a home aquarium. Their presence can be beneficial as they help maintain water quality through their filter-feeding habits. However, they require stable water conditions and should be introduced to mature systems.
