Chelonaplysilla violacea

Chelonaplysilla violacea is a sponge species primarily found in New Zealand, with occurrences across the Pacific Ocean, including regions like the Indo-Pacific, United Arab Emirates, Persian Gulf, Australia, and Hawaii. This species is recognized by its distinctive reddish-mauve coloration and a surface that appears opaque and smooth. The texture is notably slimy, soft, and compressible, with protruding horny fibers, which can help in distinguishing it from other sponge species. This sponge inhabits shallow waters, thriving at depths ranging from 1 to 25 meters. It is typically found on hard coral and rocky substrates, making it a common sight on coral and rocky reefs. The species is sessile, meaning it remains fixed in one place, and it is harmless to humans. Divers encountering this species can expect to find it in tropical waters, where it contributes to the reef ecosystem.
