Echinoderm - Asexual Reproduction: Asexual reproduction usually involves fragmentation and regeneration. Sexual reproduction involves the fertilization of eggs by spawning. Direct or indirect development results in a juvenile echinoderm. Their feeding habits range from active, selective predation to omnivorous scavenging or nonselective mud swallowing.A classificação dos equinodermos varia de acordo com os autores, porém são reconhecidas cinco classes principais: Asteroidea, Ophiuroidea, Echinoidea, Holothuroidea e Crinoidea.

Introduction: Echinoderms, a Diverse and Widespread Group of Marine Animals. Echinodermata is a phylum of about 7000 living species distributed among five classes: Echinoidea (sea urchins and sand dollars), Holothuroidea (sea cucumbers), Ophiuroidea (brittle stars), Asteroidea (sea stars), and Crinoidea (feather stars and sea lilies).A tegmen ("small leathery dome") covered the mouth and topped the cup. Any particles of food that the animal caught would be passed down the arms and below the tegmen via grooves, eventually leading to cilia, which in turn led to the mouth. When viewed from above, the stem was circular in shape. Large and small ossicles covered the stem ...Chapter contents: Echinodermata –– 1. Exclusively Fossil Taxa–– 2. Crinoidea –– 3.

Feather stars, or comatulids, are echinoderms that belong to the class Crinoidea (phylum Echinodermata) which they share with the sea lilies.

Habitat: West Atlantic stalked crinoids live in water 500 to 3,200 feet (150 to 975 meters) deep. They anchor themselves to hard surfaces. Diet: West Atlantic stalked crinoids eat plankton.(1995), habitat Crinoidea berada di dasar perairan laut lepas atau ekosistem terumbu karang yang mempunyai arus yang kuat, perairan yang jernih dan kadar oksigen yang cukup. Hal ini diperkuat oleh Yusron (2010) yang menyatakan bahwa untuk melindungi diri dari hantaman gelombang, Crinoidea hidup di daerah tebing pantai yang curam.Habitat. Crinoids frequently live on hard substratum. Some live in areas of high current flow, usually use the vertical filtration fan posture (described in the next section). Others avoid high streams and use the radial feeding posture. Nevertheless, crinoid community is probably determined by substratum complexity, independent of water flow. The larvae are bilaterally symmetrical while the adults are radially symmetrical. 4. They have organ system level of body organization. 5. They have spiny body and the endoskeleton is made of calcareous ossicles. 6. They possess water vascular system and tube-feet that help them to move and attach to the substratum.Like the crinoids, many coral-dwelling animals and plants have a diverse symbiotic fauna and flora. ...

The phylum Echinodermata is divided in five extant classes: Crinoidea (sea lilies), Asteroidea (starfishes), Ophiuroidea (brittle stars), Holothuroidea (sea cucumbers) and Echinoidea (sea urchins).
