Stelletta is a genus of sea sponges belonging to the family Ancorinidae. These sponges are primarily found in marine environments and are known for their unique structural characteristics and ecological roles.

Description

Stelletta species are characterized by their robust and often massive forms. They possess a skeleton made up of siliceous spicules, which provide structural support and deter predators. The spicules are typically arranged in a complex network, contributing to the sponge's rigidity and resilience.

Habitat

Stelletta sponges are predominantly found in marine environments, ranging from shallow coastal waters to deeper oceanic regions. They often inhabit rocky substrates, coral reefs, and sometimes sandy bottoms. Their distribution is widespread, with species recorded in various oceans around the world.

Ecological Role

As filter feeders, Stelletta sponges play a crucial role in marine ecosystems. They filter large volumes of water to extract plankton and other small particles, thereby contributing to water clarity and nutrient cycling. Additionally, they provide habitat and shelter for a variety of marine organisms, including microorganisms, invertebrates, and fish.

Species

The genus Stelletta includes several species, some of which are:

• Stelletta grubii
• Stelletta kallitetilla
• Stelletta lactea
• Stelletta normani

Research and Importance

Stelletta sponges are of interest to researchers due to their unique biochemical compounds, which have potential applications in medicine and biotechnology. Studies have focused on their antimicrobial, antiviral, and anticancer properties, making them valuable in the search for new therapeutic agents.
