Where do blacktip reef sharks live?
These sharks are common on tropical Indo-Pacific coral reefs in shallow, coastal waters. At the surface, it’s easy to spot their exposed first dorsal fins. They are homebodies. Researchers studying the population off of Palmyra Atoll in the central Pacific found the blacktips living there have a home range of around .21 square miles, among the smallest of any shark species.

They can grow to be about 7 feet, but a blacktip’s average length is a little more than 5 feet. Its maximum weight is about 30 pounds. Baby blacktip reef sharks measure about 16 to 20 inches long. We don’t know how fast a blacktip reef shark can swim, but we do know they’re a fast-swimming shark that is very active.
