Marine invertebrates, such as sea lilies and feather stars, with radiating arms and a stalk by which they are connected to the water's surface
(sea lilies) Flower-like echinoderms. They have a stalk made of calcite disks stacked on top of each other. The disks can be circular or star-shaped. The tops contained a circle of colorful arms that resembled the head of a flower. Fossil remains are found in limestone from Ordovician to Recent times. Whole fossils are rare.
Also known as feather-stars and sea-lilies. Crinoids are a group (class) of echinoderms with many movable arms and often attached to the sea-floor by a long stalk. They have a long fossil history extending back to the Cambrian Period.
a type of echinoiderm (spiny skin organism) consisting of a cup or "head" numerous radiating arms, on an elongated jointed stem and a root like structure that attached to the ocean bottom.
A member of the Phylum Echinodermata and in the Class Crinoidea. Consists of a globular body (calyx) from which extend flexible arms (brachia), and often rests on a flexible stalk. Both arms and stalk are jointed. Crinoids were very important in the Paleozoic era, with many genera having stalks. Most modern genera of crinoids do not have stalks.
sedentary marine exhibiting a mostly cup shaped body with featherly arms attached to the sea floor by a long jointed stalk
A group of marine 'sea-lilies' which attached themselves to sea-floor. Crinoids typically include a long thin stem and end with feather like arms arranged in a cup formation.
