Deep Blue is a female great white shark (Carcharodon carcharias) that is widely described as one of the largest recorded examples of the species. She was first documented off Mexico by marine researcher Mauricio Hoyos Padilla and later gained widespread public attention through media coverage of shark research and conservation.

Identification

Deep Blue is a nicknamed female great white shark (Carcharodon carcharias). She is notable because estimates place her length at about 6.1 metres (20 ft) and weight over 2,000 kilograms (4,400 lb), making her a reference point in discussions of very large great white sharks.

Discovery and sightings

The shark was first spotted by marine researcher Mauricio Hoyos Padilla in Mexico, and footage shared in 2013 helped bring her wider attention. Later reports also describe sightings near Hawaii, although published accounts differ on the timing and sequence of observations. Some sources refer to a first encounter in 1999, while others emphasize the 2013 footage as the first documented video record.

Size and significance

Published estimates place Deep Blue at roughly 6.1 metres (20 ft) long and more than 2,000 kilograms (4,400 lb), though exact measurements are difficult for free-swimming sharks. She is frequently cited in marine biology and wildlife media as one of the largest great white sharks ever documented.

Public attention

Deep Blue became widely known through Shark Week coverage and viral wildlife footage. Her size and calm behaviour in filmed encounters made her a popular example in discussions of shark conservation and apex predators.
