Marine Animal Records Quiz – Champions of the Sea

The ocean is home to many of Earth's record-breaking animals. The blue whale is the largest animal ever, while siphonophores, colonial relatives of jellyfish, may be the longest. The colossal squid has the largest eyes of any known animal.

Some marine animals set records for speed and depth. Sailfish are among the fastest fish, and Cuvier's beaked whales dive nearly 3,000 meters. Sperm whales produce the loudest animal sounds, and pistol shrimp snap claws so fast they create flashes of light.

The oceans also hold the oldest animals. Greenland sharks may live over 270 years, and an ocean quahog clam called Ming lived more than 500 years. Protecting the ocean helps these record holders continue to thrive.
