@dailydosagewildlife: The Filter-Feeding Leviathan: Basking Shark Biology The Basking Shark (Cetorhinus maximus) is the second-largest fish in the ocean, yet it relies entirely on passive filter-feeding. This video examines their specialized gill rakers—bristle-like structures that trap microscopic zooplankton as the shark swims forward with its massive mouth wide open, filtering over 2,000 tons of water an hour. We look at their massive, oily liver, which makes up a quarter of their body weight and provides the neutral buoyancy necessary to cruise the world's cold-water shelves with minimal energy. #nature #naturelover #animals #animallover #xyzbca
