How does the xestospongia muta defend itself?

Xestospongia muta, commonly known as the giant barrel sponge, defends itself primarily through its chemical defenses. It produces a variety of bioactive compounds that deter predators and inhibit the growth of harmful microorganisms. Additionally, its tough, fibrous structure makes it less palatable to many potential grazers. These adaptations help to ensure its survival in the competitive and often harsh marine environment.
