... in brittle stars and suggests additional defensive uses for vision in echinoderms. Finally, we found that animals missing a single arm orient less well to static stimuli, which requires further investigation. Light is a critical biological cue, and detecting it can play a role in habitat selection...

...Sergey V. Shabelnikov; Danila E. Bobkov; Natalia S. Sharlaimova; Olga A. Petukhova ABSTRACT Echinoderms, possessing outstanding regenerative capabilities, provide a unique model system for the study of response to injury. However, little is known about the proteomic composition of coelomic fluid...

... iodine hydrogen peroxide echinoderms 125 I Iodine is an important trace element with functions in many biological processes. For example, iodine is essential for the synthesis of thyroid hormones (THs), a group of developmental and metabolic hormones that are produced in the vertebrate...
