In general, sharks show little pattern of attacking humans specifically, part of the reason could be that sharks prefer the blood of fish and other common preys.

A 5-metre-long (16 ft) basking shark has been calculated to filter up to 500 short tons (450 t) of water per hour swimming at an observed speed of 0.85 metres per second (3.1 ...
While sharks sit near the top of the food chain in the ocean, their extinction would still have an effect on our life. Without sharks, the ecosystem would be thrown off, triggering changes to the ...
These three species are generally quite docile in disposition and given to passively filter-feeding on very small organisms. [63] This makes the great white shark the largest extant macropredatory fish. Great white sharks measure approximately 1.2 m (3.9 ft) when born, and grow about 25 cm (9.8 in) every year. [66]

Young tiger sharks are found to feed largely on small fish, as well as various small jellyfish, and mollusks including cephalopods. Around the time they attain 2.3 m (7.5 ft), or near sexual maturity, their selection expands considerably, and much larger animals become regular prey. [37]
