October 21, 2014 PowerPoint Honors Marine Biology Module 5 Bivalves Clam and Squid dissection
We are continuing our study of invertebrates to include phyla Mollusca commonly called Mollusks, and represent the most species in the ocean than any other group. They include clams, abalone, cone shells, squid and octopuses.
Experiment 5.A: Univalve and Bivalve Shell Identification
Most mollusks have a bilaterally symmetric soft body protected by a shell made of calcium carbonate. The shell provides protection from the elements and predators and can also provide body support. In our lab we identified, classified, labeled and drew various shells.
Experiment 5.B: Squid Dissection
In class we dissected a squid. View the following virtual dissections for the squid and the clam.
The quiz next week will be to label the parts of the squid. Be able to identify tentacles, suckers, arms, eye, mantle wall, mantle, gill, tail, fin and beak.
Experiment 5.1: Clam Dissection
On pages 104 -105 you will find the clam dissection. View the virtual dissection below. In your lab book draw a diagram and label the clam.
