Sandbar shark facts about a species of big fishes, also called brown sharks.

Sandbar sharks (Carcharhinus plumbeus) are a large shark species generally found in temperate, tropical, and shallow coastal waters.

These species of sharks are known to be very aggressive, and dangerous and are referred to as apex predators since they are at the top of the food chain. Sandbar sharks are nocturnal animals and are generally most active at night.

These sharks are famous worldwide as they are found in almost all places across the world.

Despite this, these species of sharks are currently Vulnerable as their populations have been decreasing at a high rate due to commercial fisheries.

Found from the western Atlantic to the eastern Atlantic, the brown shark is known to travel north during the summer and migrate back south in the winter. Females are much larger and heavier than males and are known to give birth to between seven and eight pups once every three years once they become sexually mature.

How do they communicate?

There is limited information regarding sandbar sharks' communication and behavior. Male sandbar sharks tend to bite the females during mating to flip them upside down.

Sharks have brilliant sensors which help them to find their prey and avoid larger predators. They also have an excellent sense of smell which aids them in locating their food in shallow water. Sharks can also use their electro-sensory system to be active during the night, this is known as an ampullary electroreceptor system.

How big is a sandbar shark?

Sandbar sharks can weigh as much as 100-200 lb (50-100 kg) and can grow to be 6-8.2 ft (2-2.7 m) long. Males are shorter in length when compared to the females.

How fast can a sandbar shark swim?

Sandbar sharks are known to have an estimated swimming speed of around 30 mph (48 kph). They travel continuously for days during migration in the summer.

How much does a sandbar shark weigh?

Sandbar sharks weigh around 110-220 lb (50-100 kg) which is slightly less than bull sharks. These sharks generally prey on other fishes and smaller sharks and are known as apex predators.

All commercial fishing of sandbar sharks was banned by the National Marine fisheries service in 2008, as they were declared Vulnerable due to overfishing.

Did you know...

The litter size of sandbar sharks will vary in different locations across the world, including the Chesapeake Bay, and is based on the location and temperature of the place. Sandbar sharks are most commonly found in the Chesapeake Bay.

Chesapeake Bay is deemed to be unsafe for swimming because of the number of shark species present. Females have a gestation period of one year.

The rounded snout of the sandbar shark resembles the snout of a bull shark. Sandbar sharks do not hibernate during winter, but they do migrate south to be in warmer areas.

Why are sandbar sharks important to the ecosystem?

Sandbar sharks are responsible for keeping the ocean ecosystem balanced, this job falls onto them because they eat many aquatic species. In an aquatic ecosystem, there are a lot of animals and fishes.

If the sharks are not hunting, these animals could multiply rapidly and cause problems for other aquatic animals. These sharks are apex predators and are at the top of the food chain which makes them incredibly important.
