THE BASKING SHARK

G'day folks,

Welcome to a creature you have probably never heard of. The basking shark is the second largest living fish, after the whale shark, and one of three plankton-eating sharks along with the whale shark and megamouth shark. Adults typically reach 6–8 m in length.





Basking sharks can be found in temperate waters around the globe and are the world’s second largest living fish reaching an impressive 8 metres (that’s almost the length of two cars).



Amazing Facts About the Basking Shark
  • Basking sharks live in temperate (mild temperatures) waters around the world.
  • Basking sharks are filter feeders. This means that they strain suspended matter (solid particles that float in water) and food from water (much like a strainer or sieve used in the kitchen). This is done by enlarging the mouth and passing water over gill rakers.
  • Gill rakers are growths made from cartilage that help the shark feed and prevent loose particles from passing through the gills, helping the shark to breathe.
  • Their diet consists mainly of zooplankton (tiny animals that live near the surface of water), fish eggs, barnacles and shrimp.
  • Basking sharks are peaceful animals. They do not hunt other marine animals or harm humans.
  • Due to their passive temperament, basking sharks have the smallest weight to brain weight ratio of any shark.
  • These sharks were once over exploited for their fins, liver oil and as a source of food for humans as well as feed for livestock. This has led to a decrease in population size and they are now listed as vulnerable.
  • Basking sharks can be found alone, but sometimes are found in small groups or schools of many individuals.
  • Their name comes from the fact that they look like they are basking on the water surface whilst feeding.
  • They have also been the subject of many myths and legends. In the past, fishermen and locals had reported sightings of seeing a sea serpent monster or a globster (an unidentified organic mass), most famously the Stronsay Beast. In actual fact, when a basking shark dies its body decomposes in a way that could resemble a sea monster! This is also known as cryptozoology.
