Giant Basking Shark Catch

They are slow-moving sharks (feeding at about 2 kn (3.7 km/h; 2.3 mph)) and do not evade approaching boats (unlike great white sharks). They are not attracted to chum.
Though the basking shark is large and slow, it can breach, jumping entirely out of the water. This behaviour could be an attempt to dislodge parasites or commensals. Such interpretations are speculative, however, and difficult to verify; breaching in large marine animals such as whales and sharks might equally well be intraspecific threat displays of size and strength.
• Interactions
Basking sharks are social animals and form sex-segregated schools, usually in small numbers (three or four), but reportedly up to 100 individuals. Their social behaviour is thought to follow visual cues. Although the basking shark's eyes are small, they are fully developed. They may visually inspect boats, possibly mistaking them for other basking sharks. Females are thought to seek shallow water to give birth.
