Common name: Pinecone Sponge

General information

The Pinecone Sponge, scientifically known as Sarcotragus fasciculatus, is a fascinating species of sponge found in marine environments. This species is known for its unique, pinecone-like appearance, which is characterized by its conical shape and the protruding spicules that give it a rough texture. These sponges are filter feeders, playing a crucial role in the ecosystem by cleaning the water as they feed on tiny particles and plankton.

Care

In the aquarium, Pinecone Sponges require stable water conditions with moderate to strong water flow to mimic their natural habitat. They are non-photosynthetic and rely on the water flow to bring them food particles. It is important to maintain high water quality and provide a varied diet of fine particulate organic matter, such as phytoplankton or specially formulated sponge foods.

Reproduction

Sponges have a unique reproductive strategy that includes both asexual and sexual reproduction. Sarcotragus fasciculatus can reproduce asexually through budding, where a part of the sponge breaks off and grows into a new individual. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges. The larvae are free-swimming before settling onto a substrate to grow.

Habitat

Sarcotragus fasciculatus is typically found in the Mediterranean Sea and adjacent Atlantic coasts. They inhabit rocky substrates and can be found at various depths, often in areas with strong currents that facilitate their filter-feeding lifestyle.
