Pachymatisma [Pachymatisma]

Description

Pachymatisma is a genus within the Geodiidae family, notable for its robust, often massive sponges that exhibit a velvet-like surface. These sponges are primarily found in deeper water environments, where they attach to hard substrates. Pachymatisma species are characterized by a highly dense skeletal matrix, which includes both large megascleres and smaller microscleres, providing structural support and defense.
