Agelas conifera, also known as the brown tube sponge, is a species of sponge. Its color is brown, tan, or greyish brown with a lighter interior. It is common in the Caribbean and Bahamas, and occasional in Florida.[1] Agelas conifera contains bromopyrrole alkaloids, notably sceptrin and oroidin, and levels of these feeding-deterrents increase upon predation.[2] Agelas conifera exhibit a wound response, increasing the production and release of bromopyrrole alkaloids, which appear to also protect against harmful microorganisms.
