It uses the filamentus for food , they are getting their energy from bacteria. Invasive species: neurobiology, population dynamics, hormonal control of development, functionally diverse, feeding, respiration, locomotion, reproduction.

Sponges: simples metazoans: parazoans = no tissue, no symmetry, specialized cells (4 types) Ameobocytes: produce structure in the sponge, spicules -> protein base , also reprofution and to move food around. For a large sponge, they need to filter 1 ton of water to get 1 ounce of energy: no body symmetry.
