description Basking shark Overview
With a large mouth and long gill slits, the basking shark, Cetorhinus maximus, is adapted to filtering food from seawater. It is the second-largest living fish after the whale shark and can reach about 10 meters in length. Found in temperate coastal and offshore waters around the world, it swims slowly with its mouth open, allowing water to pass across gill rakers that retain zooplankton. Despite its size, it feeds on small drifting animals rather than pursuing large prey.
Basking sharks migrate and may gather seasonally where food is concentrated, including waters off western Scotland and eastern North America. The IUCN classifies the species globally as Endangered. For readers comparing large sharks, its passive filtering method is a defining distinction. Surface feeding makes some individuals conspicuous, but those sightings represent only part of the movements and habitats used by the species.
help Basking shark FAQ
What do basking sharks eat?
Basking sharks are massive filter feeders that survive by swimming slowly with their giant mouths open to filter zooplankton from the water. They use specialized gill rakers to trap thousands of microscopic organisms as they move through temperate oceans.
How big do basking sharks get?
The basking shark (*Cetorhinus maximus*) is the second-largest living fish in the world, surpassed only by the whale shark. They can reach immense lengths of up to about 10 meters (over 32 feet) and weigh several tons.
Are basking sharks dangerous to humans?
No, basking sharks are completely harmless to humans because they are passive filter feeders that only consume tiny zooplankton. Despite their massive size and somewhat intimidating appearance, they are gentle, slow-moving creatures.
Where do basking sharks live?
Basking sharks are found in temperate coastal and pelagic waters all over the world. They are highly migratory, often spotted swimming slowly near the surface in areas where cold, nutrient-rich waters cause massive blooms of zooplankton.
