The gray reef shark, also known by the scientific name Carcharhinus amblyrhynchos, is most commonly found living in the Indo-Pacific Oceans, specifically between Easter Island and South Africa. They can also be found in the Caribbean and spend the majority of their time dwelling in the ocean’s beautiful coral reefs. Although there are some distinct differences between the grey reef shark and the great white shark, these shark species are commonly mistaken for one another. Fortunately, there are some key features that make telling these two sharks apart much easier. For instance, grey reef sharks are usually much smaller than great whites, often growing to be just 6 feet long or shorter. These aggressive, yet social sharks make up a large part of the marine life that live in these coral reefs. To learn more about grey reef sharks, take a look below!
Grey reef sharks are often confused with great white sharks, but they do have distinct features that make them unique. Just like great whites, grey reef sharks have large, round eyes, long snouts, and the classic grey upper body and a white underbelly. However, grey reef sharks are a medium-sized shark, weighing in under 75 pounds, and they have a distinctive caudal fin (tail) which has a broad, dark band that runs through it. Also, these sharks are known to develop a darker top color due to sun tanning when swimming in shallower waters. Some of the grey reef shark’s fins may also have darkened tips that help them stand out from other shark species.
Grey reef sharks tend to dominate the reef with their aggressive behavior and hunting instincts. They are very agile predators thanks to their fast-swimming capabilities as well as their ability to dive up to 33,000 feet, although they typically remain at a depth of around 200 feet. Most commonly, grey reef sharks feed on bony fishes and cephalopods such as squid and octopus. As a social species of sharks, grey reefs travel in schools of 5-20 sharks and often hunt either alone or in a small group. This allows the sharks to have the run of the reefs, threatening most other species that live there. Some have even seen grey reef sharks corner entire schools of fish into a wall along the reef, exemplifying their hunting skills.
