• 5,000 species known• Primarily marine dwelling• Body Plan
– Asymmetric
• Simplest cellular organization– No specialized systems (nervous, circulatory,
digestive)
• Filter feeder– diet of bacteria and other nutrients in water
• Sexual reproduction• 3 types of “skeleton” (some have all three)
– spongin (flexible protein)– CaCO3- shallow marine “spicules”– SiO2- deep marine
