- In a few marine species, gray cells of the sponges primitive "immune" system and can release toxins that kill all cells in the area as part of the rejection of foreign material.
- They also produce toxins that prevent other sessile organisms such as bryozoans or sea squirts from growing on or near them.
- A few species, such as the Caribbean fire sponge, cause a severe rash in humans who handle them and such toxins may protect against predators.
- The Caribbean chicken-liver sponge secretes toxins that kill coral polyps, allowing the sponges to grow over the coral skeletons.

The reasons why any animal eats a particular organism is never clear. A top reason why Nudibranchs might eat 'toxic sponges' is that there was not much else available to eat and it was easy to eat the sponges. These sponges were a niche that was unfilled and the Nudibranches adapted to take it. The sponges are still partially toxic to Nudibranchs! They often have specially lined stomachs to protect them from the sponges sharp spicules and the toxins from the sponge accumulate in them. When a predator tries to eat a nudibranch it gets a nasty mouthful of these toxins.
