Why do basking sharks only eat plankton?

These sharks feed along areas that contain high densities of large zooplankton (i.e., small crustaceans, invertebrate larvae, and fish eggs and larvae). There is a theory that the basking shark feeds on the surface when plankton is abundant, then sheds its gill rakers and hibernates in deeper water during winter.

How do basking sharks digest plankton?

DIET: Basking Sharks eat zooplankton. Long comb-like structures on their gills (known as gill-rakers) trap and filter zooplankton.

What are basking sharks favorite food?

What do basking sharks eat? Basking sharks eat plankton. Plankton is composed of very small animals (zooplankton) and microscopic plants (phytoplankton). Their preferred food is zooplankton, which is a rich mixture of shrimps, very small fish, animal eggs and larvae.

Has a basking shark ever killed a human?

There haven’t been any reported cases of basking sharks consuming humans to this point, although some divers have gotten within mere inches of the massive sea creatures! The Basking Shark mostly eats plankton and small fish, and it’s very likely that the species will deviate much from its regular diet.

What kind of food does a basking shark eat?

Their preferred food is zooplankton, which is a rich mixture of shrimps, very small fish, animal eggs and larvae. When scientists have examined the pink soup-like stomach contents of basking sharks they have found a macerated mass of zooplankton, small fish, fish eggs and, in one case, an eel.

Why does a basking shark not eat plankton?

Dr Sims has shown that basking sharks do not feed when the plankton concentration is less than 1 gram of plankton per cubic meter of water, presumably because it is energetically not worthwhile so to do [24].

How does a basking shark filter the water?

Basking sharks love zooplankton. As a filter feeder, the species follows the dense populations of plankton near the surface. When they feed, they open their massive mouths and slowly glide through the clouds of plankton as the gill rakers remove the tiny plankton from the water. A basking shark can filter millions of pounds of water per hour.

What kind of animals eat plankton in the ocean?

So many marine groups of animals feed on plankton, but baleen whales are known to be among the biggest animals that eat these small creatures. Some sharks are known to eat these little organisms: the famous Whale shark ( Rhincodon typus ), the awesome Basking shark ( Cetorhinus maximus) and the stunning Megamouth shark ( Megachasma pelagios ).
