Spinner Shark

Last updated:

The Spinner Shark is one of the requiem sharks and is part of the family Carcharhinidae. It is named for its spinning leaps as part of its feeding strategy.

This fish is found throughout warm and tropical waters. However, it does not occur in the eastern Pacific Ocean.

Spinner Shark

The Spinner Shark (Carcharhinus brevipennate) is one of the many species of requiem sharks. It is a member of the Carcharhinidae family and is named for its spinning leaps, which are an integral part of its feeding strategy.

It is found in tropical and warm temperate waters, except in the eastern Pacific Ocean.

The Spinner Shark is sometimes known by other names, including black-tipped shark, great blacktip shark, long-nosed grey shark, and sand tiger shark.

It is often caught as a bycatch in the pelagic longline fishery and by recreational anglers trolling for sharks. It is known for making vertical spinning leaps out of the water when hooked.

Its flesh is marketed as fresh, and its fins are used in making shark fin soup.

Spinner sharks feed on small cephalopods and bony fish. They typically charge schools of forage fish from beneath and erupt from the water when they’ve finished feeding.

While this species does not directly threaten humans, they are considered a threat to spearfishing divers who may come into contact with them.

Their narrow teeth make them better suited to feeding on small prey than larger ones. They are also susceptible to fishing pressure, especially when their habitat is damaged by coastal development.

The Spinner Shark is a migratory species that live in shallow, subtropical waters. During the summer months, spinner sharks migrate inshore to give birth.

Off the coast of North Africa, spinner sharks give birth to a litter of three to 20 pups. After puppyhood, they move to shallow estuaries to

protect themselves from predators.

Size

The Spinner Shark is a large, migratory shark found in temperate waters. It has a long, pointed snout and small, rounded eyes.

Its first dorsal fin is small and lacks a ridge. Its upper body and fins are bronze or gray, and its lower body is white.

Adult Spinner Sharks are about 2 meters long and weigh around 90 kilograms (123 lbs).

Spinner sharks reach sexual maturity between four and seven years of age. They breed every two years, and each generation has six to ten pups.

They typically live for between 10 and 15 years. They live in shallow waters and can be seen as far as 75 meters deep.

They average 195 cm long and weigh up to 56 kg, with the longest spinner shark measured at 278 cm.

They feed on swarms of small fish and mollusks and can be seen in schools.

Spinner sharks are a fast-swimming species, and they are often seen leaping out of the water to catch their prey.

Their long, pointed snout and small first dorsal fin help them to hunt in schools of small fish. This fish can reach speeds of 46 mph, and they typically travel in groups to look for prey.

Although spinner sharks are not dangerous to humans, they do not want to be approached.

Fishermen typically see spinner sharks during their breaching behavior and quickly move away.

This makes it difficult for the fish to approach divers. As a result, fishermen should be careful around spinner sharks, as they can be quite aggressive around bait balls and divers.

They are also highly vulnerable to fishing pressure and habitat degradation.

Spinner sharks live in subtropical and tropical waters. Their habitat includes parts of the Atlantic and Indian oceans.

They are also found in certain parts of South America and the Gulf of Mexico. They feed on small sharks, cuttlefish, squid, and octopi.

Prey

Prey of Spinner Shark

The Spinner Shark is a small but fierce predator. This fish can reach lengths of five feet and can eat nearly any prey item.

Commercial fishermen often target the Spinner Shark for its fins. The fins are used in shark fin soup, a popular delicacy in parts of Asia.

Spinner sharks usually feed on small bony fish but eat squid, cuttlefish, and octopus.

Because they are not well-equipped with cutting teeth, spinner sharks often swoop in and grab their prey whole. They typically travel in large groups to find prey.

Spinner sharks reproduce live, and their gestation period is about eleven to fifteen months. At birth, the pups are around 24 inches to 30 inches long.

The Spinner shark is an active schooling shark and often makes feeding runs through schools of fish. Occasionally, the Spinner shark will attack humans or spearfishers.

Spinner Sharks live in warm, temperate waters. They are often mistaken for blacktip sharks because they have similar features. They are fast and feed by spinning out of the water.

Commercial fishermen commonly catch spinner sharks. The Spinner Shark is a near-threatened species.

Spinner sharks are found throughout the western and eastern Atlantic Oceans. They are found from North Carolina to Venezuela.

They can also be found in the Gulf of Mexico and the northern part of South Africa. They also occur in Australia and the Philippines. During migration, spinner sharks can cross the Suez Canal.

The Spinner shark has a long pointed snout and slender body. The first dorsal fin is small and has a small black-tipped edge.

The upper and lower jaw teeth are more slender and have a smooth surface. The eyes of a Spinner shark are small and round.

Habitat

The Spinner shark is a species of fish with a wide distribution. It is found in the western and eastern Atlantic Oceans, ranging from the Gulf of Mexico to northern Brazil and Argentina.

It is also found in parts of the Indian Ocean, particularly the Red Sea and the Gulf of Aden. Its range also extends south to Indonesia, Japan, and Australia.

The species has also been known to migrate across the Suez Canal.

The Spinner shark is a viviparous fish, meaning that females give birth to up to 20 pups every two years.

Its parturition period occurs between March and April off South Africa and in the northwestern Atlantic during August.

It is an excellent source of food, and humans prize its meat.

The Spinner shark is a fast and agile swimmer, and its wide jaws help it catch prey quickly. The species usually feeds on small pelagic teleosts, including anchovies and sea catfish.

However, they are also known to eat tunas, bonito, and cuttlefish.

The spinner shark is classified as vulnerable or near threatened throughout its range. It is also susceptible to pollution, habitat degradation, and overfishing.

Commercial fishermen also target the spinner shark for its fins. These fins are used in shark fin soup, a popular delicacy in some parts of Asia.

Spinner sharks are found in subtropical and insular waters near the shelf and continental margins. They are highly migratory and are frequently found close to shore.

They feed on pelagic fishes by quickly swimming through schools, leaping, and spinning.

Some spinner sharks have been observed feeding in feeding aggregations with other species of sharks, especially blacktip sharks.

IUCN Red List status

The Spinner Shark is a species of requiem shark. It is a member of the family Carcharhinidae and is widespread throughout tropical and warm temperate waters.

However, it is absent from the eastern Pacific Ocean. Its name comes from the spinning leaps it performs as part of its feeding strategy.

The IUCN Red List outlines the conservation status of species around the world. The list is broken down into five categories that reflect each species’ relative risk of extinction.

This information is used to inform biodiversity conservation action. The Spinner Shark’s IUCN Red List status is classified into three categories: threatened, endangered, and vulnerable.

The Spinner Shark can grow to a maximum length of 3 meters and weigh up to 89 kilograms. However, the average size is much smaller at 1.95 m and 56 kg. Males reach maturity between 1.5 and 2.0 m in length.

The average lifespan of a Spinner Shark is 10 to 20 years. They are found in the northwestern Atlantic and the Indian oceans.

The Spinner Shark is gray to bronze in color with a white underside. It has five pairs of gills and a streamlined body. Its first dorsal fin is small and originates behind the free rear tip of its pectoral fins.

Its pectoral fins are small, falcate, and short. The fins are unmarked in younger spinner sharks but black-tipped in larger specimens.

The Spinner Shark is a viviparous species. Its females give birth to three to 20 pups every other year.

The spinner shark’s reproductive cycle occurs in the spring and summer off North and South Africa coasts and in the northwestern Atlantic.
