Adgressae

Adgressae are a genus of small, predatory marine animals belonging to the phylum Porifera, which includes sponges. They are characterized by their unique mode of predation, where they actively pursue and capture prey using a combination of water flow and adhesive threads. Adgressae are typically found in shallow marine environments, such as coral reefs and rocky shores, where they can easily capture small invertebrates like crustaceans and mollusks.

The body of an adgressa is composed of a central osculum, through which water is drawn in, and numerous adhesive threads called flagella. These flagella are used to capture prey by wrapping around it and pulling it towards the osculum. The captured prey is then transported to the animal's mouth, where it is digested.

Adgressae reproduce asexually through a process called budding, where new individuals grow from the parent's body. This method of reproduction allows the species to rapidly colonize new areas and adapt to changing environmental conditions.

Despite their predatory nature, adgressae play an important role in marine ecosystems. They help control populations of small invertebrates and contribute to the overall health of coral reefs. Additionally, their unique predation method has inspired research into bio-inspired technologies, such as adhesive materials and robotic grippers.

Adgressae are relatively small, with most species measuring less than 10 centimeters in length. They are typically white or light-colored, although some species may exhibit different colors due to symbiotic algae or other organisms living within their tissues. The genus is currently classified under the family Halichondriidae, which includes other sponge species with similar predatory behaviors.
