biochemicals not necessary for normal development/physiology, compounds known to be antimicrobial, antiviral, antifungal, antiprotozoa

choanocyte

like choanoflagellate, generates water current and collects particles for digestion

amoebocyte

digests food from choanocytes, and delivers nutrients to rest of the body

porocytes

main little holes on side of the cells or sponges that let water in carbonate to giev it shape and protect from predators

sclerocytes

builds up skeletal support made up of silica or calcium carbonate to give it shape and protect from predators

spongocytes

makes spongin (made up of collagen and proteins)

mammals

monotremes, marsupials, placentals

spicules

• Minute calcareous (calcium-based) or siliceous (silica-based) bodies that form the internal skeleton or supportive framework of marine and freshwater invertebrates, primarily sponges and soft corals

gastovascular cavity

the primary organ of digestion and circulation in primitive animals, functioning as a simple, two-way digestive tract with a single opening that serves as both the mouth and the anus, Cnidaria and Platyhelminthes
