A sponge's defenses are spikes in the sponges body.
Purple tube sponges have few natural enemies due to their chemical defenses and habitat preferences. However, they may be consumed by some predators, such as sea urchins, certain nudibranchs, and some fish species. Overcrowding and competition for space with other filter feeders can also pose a threat to purple tube sponges.
Sponges are animals of the phylum Porifera

Yes, they do.
