Cellepora pumicosa

Cellepora pumicosa is a sessile organism found in the Northeast Atlantic and the Mediterranean Sea. It typically inhabits depths ranging from 15 to 32 meters, often associated with rocky substrates and other hard surfaces. The species is part of the Bryozoa phylum, which is characterized by its colonial structure, forming encrusting mats that can be identified by their distinct morphology. Divers may recognize it by its branching, bushy appearance, which can sometimes be confused with other bryozoans or encrusting organisms in similar habitats. This species is hermaphroditic, meaning it possesses both male and female reproductive organs. Fertilization and egg brooding can occur either internally or externally, contributing to its reproductive success in various environments. As a filter feeder, Cellepora pumicosa plays a role in the marine ecosystem by consuming plankton and organic matter from the water column, thus contributing to nutrient cycling. Encounters with Cellepora pumicosa during dives can be intriguing as divers observe its colonies clinging to rocks or other hard substrates. The colonies can create a textured backdrop for underwater photography, adding depth to the marine landscape. The conservation status of this species has not been evaluated, indicating a lack of comprehensive data on its population trends and threats.
