How much food does a sperm whale usually eat per day?

Sperm whales usually eat a little over 900 kg (almost 2,000 pounds) of food per day. To find their prey (preferably giant squid), they dive somewhere between 300 and 1,200 metres (990 and 4,000 feet), though they can go as deep as 2 km (1.2 miles) while on the hunt. An average dive lasts about an hour.

Using echolocation to focus on their prey, sperm whales generate a series of clicks that are the loudest animal-caused noises in the world.

A sperm whale’s teeth along its bottom jaw are about 18 to 20 cm long (7.1 to 7.9 inches), fitting into sockets along the underside of the palate. The upper teeth of a sperm whale never grow out of its upper jaw.
