A galaxy of spiny brittle stars to captivate you for a moment, with a few strawberry anemones thrown in for good measure, at the Monterey Bay aquarium, California

Ophiocoma echinata

Das ist eine Schlangensternart. Wusste ich bis eben auch nicht, dass das gar keine Seesterne sind, sondern eine andere, eigene Klasse innerhalb des Stammes der Stachelhäuter (Echinodermata)😮
Auf Sand mit ein wenig Meerwasser darauf liegt ein brauner Schlangenstern mit einem runden kugeligen Dingsi in der Mitte und fünf langen Armen.

BIG BLACK BRITTLE STARS! Ophiomaza (feather star associate) and Ophiocoma! Both sizeable animals maybe 2 to 3 inches in diameter! The ridged one from central Pacific tropics, the other from Eastern tropics! #echinoday #ophiuroidea

Btw, the dancing brittle stars appear to be based on a species he thought he’d identified, which he named Ophiocoma goodsiri after his great friend John Goodsir (this species is now known as Ophiactis balli because someone else got there first with the naming)

Fun fact: brittle stars have no heart, brain, or eyes. Despite this, one species (Ophiocoma wendtii) can still see - using light receptors and colour changing cells across its body😯

This is why Barad's brittlestars don't see but touch (or rather interfere with) the world. They are just like electrons; fuzzy clouds of potential that overlay other electron-like entities and are shaped in this encounter.

Ophiocoma
Ophiocoma: Comprehensive Overview of Morphology, Classification, Habitat, Behavior, and Ecological Role Ophiocoma is a genus of brittle stars under the family Ophiocomidae within the class Ophiuroidea, phylum Echinodermata. These marine organisms are closely related to sea stars but differentiated by their slender, highly flexible arms which they use for movement and feeding. Ophiocoma species are widely distributed in tropical and subtropical oceans, primarily inhabiting coral reefs, rocky substrates, and seagrass beds.

棘皮动物“无眼之视”：色素调控与环境感知的新认知
英国牛津大学的视觉生态学家Lauren Sumner-Rooney及其团队的研究发现，与海星近亲的棘皮动物（Brittle Stars），即使没有眼睛，也能通过分布在腕足上的光感受器感知并识别图案。特定种类的棘皮动物，如Ophiocoma wendtii，在白天呈现红褐色，夜间则变为浅米色并带有条纹。 研究人员通过实验表明，棘皮动物的红褐色色素能够过滤光线，增强腕足光感受器的分辨率，从而帮助它们在明亮环境中识别环境图案，并倾向于选择有图案的区域作为藏身之处，这表明它们具备基础的视觉能力。然而，当其颜色转变为浅米色时，这种识别能力会减弱。 这一发现提示，棘皮动物的颜色变化与其“视觉”能力密切相关，可能是一种适应性机制，用于在不同光照条件下优化感知能力。此前已有海胆被证实拥有类似的无眼视觉能力，且同样具有颜色变化特征。 该研究成果发表于《Current Biology》，为理解生物界多样化的视觉系统提供了新视角，暗示可能存在大量未被发现的、利用非典型方式感知世界的生物。 查看消息来源
