California Ball Sponge

Tetilla arb

California ball sponge is primarily found in the Eastern Central Pacific region, particularly along the coast of California, USA. Divers can encounter this species at various dive sites near DiveSight locations. The California ball sponge is sessile, meaning it remains attached to the substrate in its habitat. This species is typically found in subtropical waters, with a significant majority of occurrences recorded at depths shallower than 40 meters. It is most commonly observed at depths of less than 30 meters, making it accessible for divers exploring these regions. Divers encountering this sponge can expect to see it firmly attached to the substrate, contributing to the complex underwater ecosystems in which it resides.
