Mighty mollusk

Giant clams are are the largest mollusks on Earth. They can grow up to 4 feet (1.2 meters) in length and weigh more than 500 pounds (227 kg). This one was about 3 feet long. I patted his exterior shell which caused him to clam up and shut his shell.

Low Isles, Great Barrier Reef, Australia.

My husband took this photograph, but I am posting it for him since he does not have an ipernity account..
