In addition, brittle stars are able to see with the whole surface of their rounded body. Special crystalls are embed in it's skin, and each gets a little segment of the whole picture. Scientists from States have compared the principles of ophiura's viewing with the matrix of a digital camera, where a complicated image is formed out of plenty simple image-pixels.
Ophiuras avoid direct sunlight, and doing it's best to escape rapidly back to the shadow of stone by swinging and waving it's arms if being exposed to.
Be careful when touching ophiura: it drops an arm as easy as an escaping lizard it's tail. An arm continues to crawl by clutching and meandering, that gives quite a surrealistic feeling.
A former owner of an autotomed arm will grow a new one in a short time, but we would not like to cause them even smallest troubles, would we?...
