Before we dive in to where to find the most promising places to dive with blue sharks, let us give you some background information about them.

Endangerment of Blue Sharks

Blue Sharks are decreasing in number worldwide as 10 to 20 million sharks are killed per year by humans. This makes the blue shark the most heavily caught fish on earth.

Primarily, the shark’s fins are sought after by shark-fin soup enthusiasts. Decreasing the demand for this soup could already help to contribute conserving this beautiful and gentle shark species. Aside from the fins, blue sharks are not particularly tasty. Hence, the rest of their bodies are mostly used for fish meal production.

Blue Sharks are incredibly gentle creatures towards humans. Let’s focus on just observing instead of overfishing them.

Geographical Distribution of Blue Sharks

The blue-shark lives usually off the coast-shelf and dives into a depth of approximately 350 meters. It occurs as a resident in all tropical to temperate sea areas and is probably the most widespread species of all sharks.

Very often blue sharks are sighted in the North Atlantic from the south coast of Great Britain to Senegal as well as around the Azores, the Canary Islands, Cape Verde, and Madeira. Blue sharks also populates the Mediterranean Sea and is a summer visitor to the North Sea, the Skagerrak, and waters off Norway. In the Northwest Atlantic, it is mainly found far off the coast of Florida and the Antilles, where it is a summer guest in the Gulf of Maine, off Newfoundland and Nova Scotia.

In the South Atlantic, the shark regularly occurs as a deep-sea species off South Africa and off the South American coast (Argentina, Brazil, Uruguay). Also, in the Indian Ocean, blue sharks are occasionally found between the 35th and 13th southern latitude; near the coast (for the ones of you who are into geography ;P). In the Pacific ocean, it can be found in all warm temperate areas.

Diet of Blue Sharks

The blue shark, as a large deep-sea shark, eats almost everything it can capture. The main part of its food represents fish of any size, mainly schools of fish such as herrings, mackerels, sardines or tunas. In addition, it hunts smaller shark-types. 

Fishery-remains thrown into the sea supplement their diet. Unfortunately, indigestible garbage can also be found regularly in its stomach.

Best Places to Dive with Blue Sharks

Every summer the blue shark appears with the Gulf Stream off the coast of the British Isles. Blue sharks live in tropical waters around the world.
The gentle blue shark people knew until the late 40’s only from isolated blue sharks, that were caught before the English channel-coast. They were found in the long nets, which were designed for sardines. The strong fish had got caught in the nets during their attempts to escape and had destroyed many nets.

Shortly after the Second World War, Brigade Commander J.A.L. Caunter began to catch blue sharks from the boat in Looe, Cornwall. He found that blue sharks are quite abundant along the Cornish coast. From that moment on, blue shark fishing at Looe developed into a small industry in its own right. However, in recent years the stocks have been declining due to overfishing. So please STOP fishing for blue sharks.

Fun Facts About Blue Sharks

1. The largest caught blue shark

Blue sharks, with slim bodies and long pectoral fins, usually grow to 7-9ft/2.5-3m. The largest blue shark ever caught was 9 ft/3 meter long and weighed 256 LBS. It took four experienced fisherman to get this fantastic creature out of the sea close to the coast of England. The fished blue shark was later released back into the sea where he reportedly was able to swim away.

2. Blue Sharks are Explorers

Blue sharks need space. As they are used to the open water, it is no surprise that they not do well in captivity. The first attempt of keeping blue sharks in captivity was at Seaworld San Diego in 1968. The longest a blue shark was ever kept in captivity was 246 days in an aquarium in Tokyo.

3. Blue Sharks the Reproduction Machines

Blue Sharks give birth to between 40 and 63 babies dependent on the age and the size of the mother. The young sharks feed in the mother’s uterus on a yolk in the form of a yolk bag and are about 50 centimeters long at birth. The gestation period is between nine and twelve months.

From a length of about 2.20 meters the females become sexually mature, which corresponds to an age of four to five years. Nothing is known about the onset of sexual maturity of the males, but they are also believed to be of reproductive age from about four to five years. The oldest until today known animal was approximately 20 years old.

4. A Two Headed Blue Shark

In 2011, scientists, found two-headed female blue shark embryos. They were found inside a pregnant adult female that had been caught in the Gulf of California off the western coast of Baja California Sur, Mexico.

A researcher, Felipe Galván-Magaña, speculated, “Abnormal sharks showed a symmetric bicephaly that could be caused by the high number of embryos found in the uterus of the blue shark, which is the most fecund species of shark in the world. The abnormality probably began during the embryonic development.”
