What Do Basking Sharks Eat? Their Diet Explained
A-Z-Animals.com
Basking Sharks are one of the ocean’s most mysterious marine life. They are the world’s second-largest fish right after the whale shark. Despite being related to the great white and having a predatory look, they are a gentle mackerel shark that survives off planktonic life. Let’s take a look at what basking sharks eat and the unique way they feed.

Basking sharks are one of three species of sharks that are filter feeders. Unlike the other two species of filter-feeding sharks, the basking shark cannot suck water through its mouth and must passively feed. They swim through the water opening their large 3 foot (0.9 meters) mouth to collect plankton in long gill rakers, closing it occasionally to swallow and filter the plankton.
Basking sharks are migratory and will feed while traveling long distances. They are often seen near the surface of the water slowly moving at around 2.3 mph (4 kph). While it may look like they are basking in the sun, they are feeding off dense pockets of plankton near the water’s surface. Their gaping mouths filter water through their gills and the small plankton gets captured by the gill rakers, which are long and comb-like.
Basking sharks will feed in water with dense plankton pockets and will form large groups of up to 100. While their largemouth looks intimidating they will only eat small plankton and will go out of their way to avoid large objects.

Plankton is the main source of food for the basking shark but what exactly is it? Plankton is classified as a marine drifter and is an organism unable to swim, carried by the tide. There are two main types of plankton; phytoplankton, and zooplankton. The basking shark’s preferred food is zooplankton, specifically copepods.
Copepods are small crustaceans that are microscopic. Below you can see a zoomed in picture of what copepods look like under a microscope, enjoy how many of these basking sharks need to eat to consume their regular diet every day!

Basking sharks seek out copepods but other zooplankton may also be consumed like:
Annually in the winter basking sharks shed their gill rakers. Hibernation or a change in diet are some theories to what happens until they regrow them in spring.

Being ginormous, basking sharks need to eat a large amount of plankton to survive. Over 2,000 tons of water are filtered per hour by their gills. Since plankton is so small they must eat millions each day which can equal hundreds of pounds.
