spinner shark
The spinner shark is a member of the requiem shark family. Other requiem sharks are tiger sharks, blacktip sharks, grey reef sharks, and blue sharks.
It gets its name from its ability to spin through the water and into the air. It can also leap into the air from the water and spin several times in a row. With incredible speed and powerful jaws, the spinner shark is a highly successful predator.
The shark’s sleek, aerodynamic body is usually gray or silver in color with black tips on its fins. Because of those dark tips, it is frequently confused with the blacktip shark, but they are separate species.
5 Incredible Facts
* When chasing fish, the spinner shark spins while snapping its jaws.
* A spinner shark can have up to 20 live babies, which are known as pups.
* Spinner sharks can also spin and rotate up to three times while jumping into the air.
* They prefer shallow waters close to the coastline.
* Spinner sharks rarely attack humans.
Classification and Scientific name
The spinner shark’s scientific name is Carcharhinus brevipinna.
Appearance
A spinner shark’s length can range from 6 to 9 feet. They weigh from 120 to 200 pounds. Biologists note that spinner sharks from the Indian and Pacific oceans are usually larger than those in the Atlantic.
They have 15 to 18 teeth in each half of their upper jaw and 14 to 17 in each half of their lower jaw. Their serrated teeth and serve them well as predators.
These sharks have long, sleek bodies and incredible speed. That makes them ideally suited to hunting schools of small fish. They swim through the schools, spinning and snapping their jaws to catch all the fish they can.
Their bodies are usually bronze or gray above and white below.
Distribution, Population and Habitat
These sharks live in the warmer oceans of the Pacific, Indian, Mediterranean, and Caribbean. They prefer warmer water, and those in the colder Atlantic waters are usually migratory. They travel to warmer waters to fish and breed.
Spinner sharks have been spotted in the waters off Cuba, the Bahamas, Brazil, and Argentina. Many islands of the Indian Ocean, including Madagascar, have them in their waters. They have also been found in Australia, Sumatra, and Vietnam.
These sharks prefer shallow water that is no more than 98 feet deep. When hunting fish, they can drop to depths of 300 feet.
Predators and Prey
These sharks have few natural predators. Sometimes, large sharks will eat small spinner sharks.
They are carnivores and excellent hunters. They prefer to catch their prey in schools of sardines, herring, and other fish, but they will also eat larger fish like tunas, bluefish, and stingrays. The sharks travel in small groups and frequently hunt together.
Their chief predators are humans who hunt them for their fins and meat. Illegal hunting of sharks for the Asian fin trade has devastated many shark species. In a practice known as shark finning, hunters catch them and saw off their fins before throwing the live sharks back into the water. Sharks then sink to the bottom of the ocean. Unable to swim or catch prey, the sharks die a slow, painful death.
According to Sea Save, shark finning kills more than 100 million sharks every year. Conservationists are trying to pass laws that would ban the import of shark fins from the U.S. and other countries.
Habitat loss is another threat to spinner sharks. The International Union for the Conservation of Nature (IUCN) lists them as near threatened.
Reproduction and Lifespan
These sharks reach sexual maturity at age 12. They mate in the spring and summer and give birth every other year. After a gestation period of 11 to 15 months, the female travels to a shallow location, where she gives birth to 3 to 20 pups. Each baby shark is about two feet long at birth, but they grow rapidly. Most of them reach their adult size in a few years.
Jumping for Joy
These sharks are among the many unique animals that give the ocean its amazing diversity. Watching them jumping and spinning is an unforgettable sight. With care and conservation, we can continue to enjoy these and the other magnificent beasts of the sea.
