Common name: Deadman's Finger sponge

General information

Bowerbank's Sponge, scientifically known as Halichondria bowerbanki, is a species of marine sponge found in various parts of the world's oceans. This sponge is characterized by its irregular, massive form and its ability to grow on a variety of substrates, including rocks and shells. It has a rough, uneven surface and can vary in color from yellow to dark brown. As a filter feeder, it plays a crucial role in the marine ecosystem by filtering water and removing particulates.

Care

In the aquarium, Bowerbank's Sponge requires a stable environment with strong water flow and good water quality to thrive. It is a non-photosynthetic species, which means it does not rely on light for its nutrition. Instead, it feeds on dissolved organic matter and plankton in the water column. Hobbyists should ensure that the sponge is never exposed to air, as this can cause tissue damage and death.

Reproduction

Reproduction in Halichondria bowerbanki is both sexual and asexual. Sexual reproduction occurs through the release of sperm into the water column, which then fertilizes eggs within another sponge. Asexual reproduction can happen through budding or fragmentation, allowing the sponge to spread and colonize new areas.

Habitat

Bowerbank's Sponge is found in a range of marine habitats, from shallow intertidal zones to deeper subtidal areas. It is often seen in areas with strong currents, which facilitate its filter-feeding lifestyle. This sponge is adaptable and can be found in various geographical locations, including the Atlantic coasts of Europe and North America.
