In zoology, the epidermis is an epithelium (sheet of cells) that covers the body of a eumetazoan (animal more complex than a sponge).

See Ossicle (echinoderm) and Epidermis (zoology)

Exoskeleton

An exoskeleton (from Greek έξω éxō "outer" and σκελετός skeletós "skeleton") is a skeleton that is on the exterior of an animal in the form of hardened integument, which both supports the body's shape and protects the internal organs, in contrast to an internal endoskeleton (e.g.

Goniasteridae

Goniasteridae (the biscuit stars) constitute the largest family of sea stars, included in the order Valvatida.

Larva

A larva (larvae) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage.

Ligament

A ligament is the fibrous connective tissue that connects bones to other bones.

Luidia

Luidia is a genus of starfish in the family Luidiidae in which it is the only genus.

See Ossicle (echinoderm) and Luidia

Madreporite

The madreporite is a light colored calcareous opening used to filter water into the water vascular system of echinoderms. Ossicle (echinoderm) and madreporite are echinoderm anatomy.

Order (biology)

Order (ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy.

Paxilla (ossicle)

A paxilla (plural. paxillae) is a small umbrella-shaped structure sometimes found on Echinoderms, particularly in starfish (class Asteroidea) such as Luidia, Astropecten and Goniaster that immerse themselves in sediment. Ossicle (echinoderm) and paxilla (ossicle) are echinoderm anatomy.

Pedicellaria

A pedicellaria (pedicellariae) is a small wrench- or claw-shaped appendage with movable jaws, called valves, commonly found on echinoderms (phylum Echinodermata), particularly in sea stars (class Asteroidea) and sea urchins (class Echinoidea). Ossicle (echinoderm) and pedicellaria are echinoderm anatomy.

Polarization (waves)

italics (also italics) is a property of transverse waves which specifies the geometrical orientation of the oscillations.

Sclerocyte

Sclerocytes are specialised cells that secrete the mineralized structures in the body wall of some invertebrates.

Tube feet

Tube feet (technically podia) are small active tubular projections on the oral face of an echinoderm, such as the arms of a starfish, or the undersides of sea urchins, sand dollars and sea cucumbers; they are more discreet though present on brittle stars, and have only a feeding function in feather stars. Ossicle (echinoderm) and tube feet are echinoderm anatomy.
