Giant Basking Shark Catch

Basking sharks have few predators. White sharks have been reported to scavenge on the remains of these sharks. Killer whales have been observed feeding on basking sharks off California and New Zealand. Lampreys are often seen attached to them, although they are unlikely to be able to cut through the shark's thick skin.
• Diet
The basking shark is a passive feeder, filtering zooplankton, small fish, and invertebrates from up to 2,000 short tons (1,800 t) of water per hour. They feed at or close to the surface with their mouths wide open and gill rakers erect. Unlike the megamouth shark and whale shark, the basking shark does not appear to actively seek quarry, but it does possess large olfactory bulbs that may guide it. It relies only on the water it pushes through its gills by swimming; the megamouth shark and whale shark can suck or pump water through their gills.
