1. Identify the Phylum.
2. List the difference(s) between this and another similar and often confused class.
3. (About the class)Describe the difference between the pedicle valve and the brachial valve.
4. Describe their common feeding organ and how it works.

1. Brachiopods
2. Class Inarticulata (inarticulates are held together entirely by musculature)
3. Pedical is the top, brachial is the bottom??
4. Lophophore: it has cilia like tentacles that are used to gather food

[color=#FF0000][b]Nice try here- I think you got confused. I meant the class outside Brachiopoda, Bivalvia. The two are often confused as brachiopods have their plane of symmetry in the center, divding them into left and right parts, while bivalves are divided in two by the top  and bottom, creating the two (bi) valves (valvia).[/b][/color]

3. Pedical is the top, brachial is the bottom??
[color=#FF0000][b]More detail would be a little better- pedicle has an indent, while the brachial sticks a bit out.[/b][/color]
4. Lophophore: it has cilia like tentacles that are used to gather food
Nice, go ahead! (check in hide box for corrections)

Bivalves are a phylum, not a class...

No- they are a class under Mollusca, check the list or any site

Did I say Brachiopoda was a class? If so, sorry about that...
