How large do white sharks get?
The longest white sharks accurately measured range from 19 to 23 feet (5.8 to 7 m). A 21-foot (6.4 m) white shark was estimated at 7,000 pounds (3,175 kg). White sharks eat fishes until they reach large size, and then they switch to seals, sea lions and other marine mammals while continuing to eat some fishes. No one knows how long white sharks live, but 20 years may well be a conservative estimate.
