This black with a tinge of red colored crinoid is in one of its usual places, hanging out on a fan. This primitive kind of starfish often is seen having crawled out on a fan that is cross current in order to feed from the nutrients flowing by in the water. For more about these creatures that fascinate me so much see Orange Crinoid Curl.
There are several other crinoid images in my portfolio - to start see Light Pink Soft Coral with Crinoids and Crinoid and Soft Coral Bouquet.
This is available up to 13 x 20 and on cards.
