Hello, Your response expresses the content of the passage well, but needs a little improvement: According to the speaker, the clam lives in the ocean and has a two-part shell that it can open very wide. When an undersea diver swims near the clam, a part of his body may touch the clam's shell or even enter into it. This could happen because the diver is so interested in examining the clam or in looking for a pearl inside its shell that he gets too close.
