1. The Brachiopod Saga By: Tony Jasper

2. Morphology Important Features:
Lophophore- Circular structure with tentacles in the mantle cavity used for filter feeding (bryozoans have these as well-they are another lophophorate)
Pedicle- Muscular stalk that attaches the brachiopod to something else

3. Chemosynthetic Environments
Hot Springs (like Yellowstone)
They like hot, deep waters with mid-ocean ridges - A.K.A. places with high geothermal gradients
Cold seeps of petroleum and gas- this creates a community of invertebrates like brachiopods, clams, tube worms, and crustaceans
