Cryptodendrum adhaesivum, the pizza anemone (family Thalassianthidae), is found in shallow Indo-Pacific reef environments with highly adhesive tentacles arranged in two distinct morphological zones covering the oral disc. The species is notable for its symbiotic relationship with clownfish, particularly Amphiprion clarkii, across the Indo-Pacific. Its distinctive two-zone tentacle organization distinguishes it from other host anemone species. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
