These are the jewels of the seas, feather dusters floating with the currents. Their name, feather star, tells us about the stars and the feathers. Softness and glitter in an ocean of blue. A true tale that no poet has ever written. In fact, we do not know any stories about these fluffy stars. And yet, like their close cousins, the starfishes, they should hold our attention as they could seduce us. But it is not badly guided or badly informed that we do not find them in the biggest aquariums of the world, but because their beauty can not acclimatize of such an environment. In fact, we are still very ignorant about crinoids, their scientific name. But what are they exactly? A star made of feather? Or feathers made stars?
