Sharks eat different then other fish. Having skeletons made of tough, rubbery cartilage. They also have a strong sense of smell, acute hearing, excellent eyesight, and a special ability to recognize electric and magnetic fields. This unique sense can aid both in the location of prey and in navigation.

The shark's powerful tall and stabilizing fins make it an efficient swimmer. While tall, fins vary in size. They all contribute to the graceful curve and muscular swish associated with these predatory creatures. Not all sharks must keep moving to survive. Many are able to rest on the bottom for extended periods by actively pumping water over their gills.

This shark has bands and spots. They lay eggs which develop and hatch within 4 months. Bamboo shark is found in the Indo-West Pacific from Japan to northern Australia, between latitudes 34° N and 26° S, to depths of 85 m. Its length is up to 1.04m.

-History- The horseshoe crabs are world's oldest and most fascinating creatures. They are at least 300 million years old. Thousands of other species have come and gone when Earth's land masses have shifted, but horseshoe crabs have survived and today remain much as they were those millions of years ago.
