Velvet Sponges [Dictyodendrilla]

Description

Dictyodendrilla is the sole genus in the family Dictyodendrillidae, known as Velvet Sponges. These sponges are characterized by their unique velvety texture, which is attributed to the dense mat of spicules that cover their exterior. These spicules, primarily made of silica, form a protective layer that can vary in color from deep red to brown or even a striking blue, depending on the species. Velvet Sponges are found in a variety of marine environments, from shallow waters to deeper oceanic zones, where they attach to substrates such as rocks or coral reefs. They play a crucial role in the marine ecosystem by filtering water to feed, thereby removing particulate matter and potentially harmful bacteria from the water column. Additionally, their complex structure provides habitat and protection for a variety of marine life, including small fish and invertebrates.
