General characteristics of Phylum Echinodermata (Echinos: Spines; derma: Skin) Kingdom: Animalia; Habitat: These are exclusively marine; Grade of organization: organ system grade ; Germ layer: triploblastic; Symmetry: Adults are radially symmetrical while the larvae are bilaterally symmetrical. These are very familiar as parasitic worms causing diseases, such as the worms causing elephantiasis (filarial worms) or the worms in the intestines ( roundworm or pinworms ). The mouth is surrounded by 10-30 mostly 20 peltate or branched oral tentacles. The body is flattened with a pentamerous or rounded central disc. This phylum consists of radially or radially symmetrical aquatic invertebrates having unique stinging structures in the tentacles surrounding the mouth.

Invertebrates are animals that lack a backbone and comprise 95% of the Animal Kingdom. Rastogi Publications. Starfish can move using specialized structures called tube feet. Echinoderms are separated into 21 classes, based mainly on differences in skeletal structures. In most extant crinoids, primarily the shallow-water ones, there are two body regions, the calyx and the rays.The calyx is the cup-shaped central portion that lies below the oral surface, which is oriented away from the substrate; most of the organs are . !function(a,b,c){function d(a,b){var c=String.fromCharCode;l.clearRect(0,0,k.width,k.height),l.fillText(c.apply(this,a),0,0);var d=k.toDataURL();l.clearRect(0,0,k.width,k.height),l.fillText(c.apply(this,b),0,0);var e=k.toDataURL();return d===e}function e(a){var b;if(!l||!l.fillText)return!1;switch(l.textBaseline="top",l.font="600 32px Arial",a){case"flag":return!
