Author Description

Excerpt from Juvenile Instructor, Vol. 28: May 15, 1893 Most of the crinoids are provided with a long, exible stem, the lower end of which spreads in a root-like manner; and by this the animal is attached to a stone or some other submerged object, or even to the mud at the bottom of the water. The free end of the stalk bears a cluster of rays, in number usually five, or arranged in five groups. The food is caught by the spreading tentacles, and forced into the mouth, situated at the center of the disc, from which the rays diverge; the mouth leads to an alimen tary canal, by the walls of which the nutritive matters are absorbed.
