Spongia [Spongia]

Description

Spongia is a genus within the family Spongiidae, known commonly as bath sponges. These sponges are characterized by their fibrous skeleton and large oscula (exhalant pores). They are found in shallow waters and are often harvested for commercial use due to their absorbent and durable skeleton. Spongia species are typically encrusting or lobate and vary in color, although many are a dark brown or black when alive. They have a relatively simple body structure with channels and chambers that facilitate the flow of water, allowing them to filter feed on plankton and organic particles.
