The existence of diverse symbiotic relations between echinoderms and various kinds of organisms have been recorded both in the fossil record and in the Recent (e.g., Tapanila, Reference Tapanila 2008; Boucot and Poinar, Reference Boucot and Poinar 2010); subsequently, some of these relations may generate an ichnological record.

Anemone form symbiotic relationships with the clownfish, shrimp, hermit crabs, and pom pom crabs. Although this blurs the symbiotic relationship between the two organisms and risks infection for the hosts, elephants and zebras may find this a small price to pay for the oxpeckers’ cleaning service.

The parasitic fauna differs markedly according to the echinoderm group concerned, depending on various factors such as feeding-habits or symbiogenesis. When they are newly diagnosed with celiac disease, many people also discover that they are lactose intolerant and have difficulty digesting milk and products or they may cause burning, Stomach ulcers often are not consistent. These organisms aren’t stung because their mucus/slime coat chemicals mix with that of the anemone so it does not set off the chemical sensors on the cnidocytes.

Symbiotic Relationship of Thiothrix spp. Add to Cart Ophiuroidea (brittle stars and basket stars): The physically largest of echinoderms; about 1,500 species, the largest echinoderm class. Some echinoderms also engage in symbiotic relationships. Oxpeckers are not always helpful, though. For example, there are some polychaete species (annelids, Polychaetae) that live on asteroids and feed on stray food particles that do not make it into the sea star’s mouth.

This is the first evidence for a possible association of a boring polychaete not only with an echinoid but with an echinoderm in general. Crossref. Echinoderm. 1997. An example is a golden jackal (the commensal) following a tiger (the host) to feed on leftovers from its kills. Echinoderm is the common name given to any member of the phylum Echinodermata (from Ancient Greek, ἐχῖνος, echinos – "hedgehog" and δέρμα, derma – "skin") of marine animals.The adults are recognizable by their (usually five-point) radial symmetry, and include starfish, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies".
