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.

The sawfish's saw is actually an elongation of their head lined with teeth. It contains thousands of ampullary pores which the sawfish uses to detect minute electric fields which surround its prey. The saw is used to find food by digging in the ocean's bottom and by slashing free-swimming fish.
