Porifera

Hexactinellida
-Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed silaceous spicules, often referred to as glass sponges
Demodpongiae
The largest class in the phylum Porifera.
Calcarea
members of the animal phylum Porifera, the cellular sponges.
Asconoid
Simplest form of sponges, with canals leading directly from the outside to the interion.
Syconoid
sponges are similar to asconoids. They have a tubular body with a single osculum, but the body wall is thicker and more complex than that of asconoids and contains choanocyte-lined radial canals that empty into the spongocoel
Leuconoid
A type of canal system in sponges where choanocytes reside in chambers.
Choanocyte
One of the flagellated collar cells that line cavities and canals of sponges.
Pinacoyte
Flattened cells composing dermal epithelium in sponges.
Spongin
Fibrous, collagenous material forming the skeletal network of horny sponges.
Spicules-
Each of the small needlelike or sharp-pointed structures of calcite or silica that make up the skeleton of a sponge-Each of the small needlelike or sharp-pointed structures of calcite or silica that make up the skeleton of a sponge
Ostia
a series of tiny pores all over the body of a sponge that let water into the sponge.
Oscula
A large aperture in a sponge through which water is expelled.
Suspension Feeding
An aquatic animal, such as a clam or sponge, that feeds by filtering tiny organisms or fine particles of organic material from currents of water that pass through it.
Pinacoderm
The layer of pinacocytes in sponges.
Phagocytosis
The engulfment of a particle by a phagocyte or a protozoan.
Archaeocytes
Ameboid cells of varied function in sponges.
Spongocoel
Central cavity in sponges.
Radical Canals
Canals along the ambulaera radiating from the ring canal of echinoderms; also choanocyte-lined canals in syconoid sponges.
Mesohyl
Gelatin matrix surrounding sponge cells; mesoglea, mesenchyme.
Sclerocyte
An amebocyte in sponges that secretes spicules.
Spongocyte
A cell in sponges that secretes sponging
Collencyte
A type of cell in sponges that is star shaped and apparently contractile.
Monoecious
Having both male and female gonads in the same organism; hermaphroditic.
Gemmule
Asexual, cystlike reproductive unit in freshwater sponges; formed in summer or autumn and capable of over-wintering.
Porifera
Porifera- A grand division of the Invertebrata, including the sponges
