Ostia

minute, pore-like openings on the surface of sponges (phylum Porifera) that allow water to flow into their bodies for feeding, respiration, and excretion

Osculum

a large, specialized opening in a sponge (phylum Porifera) through which water is expelled after filtration.

Class Demospongiae

Typically have spicules made of spongin,

Spongin

a modified type of collagen protein that forms fibers that hold spicules together.

What class are these sponges in? (Loggerhead, Vase Sponge, Bath sponge, Spongilla, etc.)

Class Demospongiae ; Phylum Porifera

Spongilla

a genus of freshwater sponges (Phylum Porifera) found worldwide in clean lakes, ponds, and slow streams, often attached to submerged rocks or wood. They are sessile filter feeders, appearing green due to symbiotic zoochlorellae algae. Spongilla reproduces sexually via larvae and asexually through dormant, overwintering gemmules.
