Two blue sharks swim in formation in Pico Island, Azores Some of the best places to photograph blue sharks are in South Africa, Baja California (Mexico), Rhode Island and California in the US and Portugal’s Azores Islands. Although numbers are in decline, hotspots remain where it is still possible to reliably encounter this species. It feeds mostly on small bony fish, such as herring and mackerel, and invertebrates such as squid, cuttlefish and crabs and shrimps, but this is an opportunistic predator that will also target fishing nets and scavenge on dead whales and other animals.ĭue to its long migrations and pelagic habitat, it is one of the most vulnerable of all shark species, and in recent years commercial fishing has decimated populations worldwide. In temperate seas, it may approach the surface, where it can be observed by divers and fishermen but, in tropical waters, it tends to seek deeper water with cooler temperatures in its preferred range of 54 to 68 degrees Fahrenheit. Shaped like a torpedo, with large pectoral fins and a long slender body perfectly suited to long-distance travel, blue sharks can be found in both temperate and tropical waters around the world, where it roams the vast expanse of the open ocean in a constant search for prey. This contrast in colors is known as countershading, and provides the ideal camouflage for hunting in the pelagic zone.

The shark is named after its distinctive indigo blue skin color on the top of its body that gradually becomes lighter towards the edges and bright white underneath. The latest installment of our “how to shoot sharks series” focuses on the blue shark ( Prionace glauca), a pelagic species that is a much sought after subject for dedicated shark divers and underwater photographers all over the world. "Thank you all for the surface support, surface photos and videos, and putting up with the smell," half-joked Mohler to fellow divers in his Facebook post.ĪBC-affiliate KITV reported that Deep Blue found the whale carcass after it washed up on Sand Island last week, and was later towed out into the ocean.Blue sharks are an inquisitive pelagic species making for excellent photo opportunities Mohler wrote that fellow diver Kimberly Jeffries was the first to see her on 13 January, and the pair confirmed Deep Blue's identity with the white shark authority.Īs Deep Blue fed, she spread "chunks of whale and oil" in the water, he wrote. He said she had come to Hawaii for an "all-you-can-eat vacation." Mark Mohler, a diver who snapped photos of Deep Blue, wrote on Facebook: "Deep Blue, possibly the biggest White Shark identified, coming in at nearly 7 meters, was last spotted in Mexico." "I think the sperm whale kind of presented an opportunistic foraging opportunity so that's probably why people saw this animal," Hutchinson said.ĭivers were able to identify the shark as Deep Blue thanks to a tag she was given when she was found off the coast of Guadalupe Island around two decades ago. The sharks generally gather in Hawaii in the winter when they carry out deep dives during the day, she said, meaning they're not typically spotted by humans. "About 20% of the population from California and Mexico migrate here every year or every other year," Hutchinson explained. The animals have been gathering in the spot "forever," she added. She said it was a "fun surprise" for them when they noticed her. Hutchinson said some of her friends were out at sea searching for tiger sharks when they spotted Deep Blue.
