Petrosia [Petrosia]

Description

Petrosia is a key genus within the family Petrosiidae, recognized for its significant contribution to marine biodiversity. These sponges exhibit a wide range of forms from thick encrustations to massive, blocky shapes. Their structure is reinforced by a dense network of spicules that makes them very hard and resistant to predation. Petrosia species are found in diverse marine environments, where they serve as important habitat builders and participate in the cycling of nutrients. They are particularly noted for their symbiotic relationships with various microorganisms, including bacteria and algae, which can influence their color and chemical composition.
