The scyphostoma larva (the fixed polyp-like stage in the life cycle of a jellyfish, which reproduces asexually) of Nausithoe punctata bears a striking superficial resemblance to a hydroid and it lives commensal within sponges. This hydroid-like larva forms a branching tree-like growth within the body of the sponge, the polyp mouths and their tentacles projecting out of the oscula (mouthlike aperture) of the sponge. The mouth of the polypite is surrounded by an annulus of about 40 solid filiform tentacles. The ephyra (immature medusa stage) of Nausithoe arise by strobilization (asexual reproduction by division into segments) from this larva. The young ephyra has only 4 gastric filaments and no tentacles. The species occurs in the North Atlantic Ocean in the Mediterranean Sea and circumglobal in warm waters. Max. diameter of adult Nausithoe punctata is 1.5cm. Many Brittle stars Ophiothrix sp. and a Red throated Ascidian Herdmania momus just below. Palau, Iro Wreck 7°17'39.7 N 134°25'15.18 E at 10m depth
