Sharks are top predators in many marine communities, yet few studies have quantified or determined those factors influencing their distribution and hunting behavior. Previous studies showed tiger sharks also engage in yo-yo diving behavior but the reasons were unclear. Now, researchers from the United States and Canada are using geographic profiling -- a criminal investigation tool used to track a connected series of crimes and locate where serial criminals live -- to examine the hunting patterns of white sharks in South Africa. The sharks featured in the film are actually known for being relatively shy and almost never attack people. These include cetaceans, fishes, pinnipeds, sea turtles, and even seabirds. These sharks are one of a handful of shark species that are quite social. While spinning, it blasts through groups of fish and snap their jaws in all directions. The researchers placed blacktip, bonnethead, and nurse sharks—three species found along Florida’s coast that differ in body structure, hunting strategy, and habitat—into a large, specially designed tank where the water flowed straight toward them. Several shark species display this behavior in situations dealing with territory, mates, and predators. It could mean that even though they are hungrier, they will have a harder time finding prey, and would end up eating less. Since 2009, DMF biologists (and collaborators) have been examining the movement ecology, behavior, natural history, and population dynamics of this species through its Shark Research Project. This phenomenon is most likely hardwired into the shark’s behavior due to their evolution as a species. How do Great White Sharks attack their prey – Summary of Strategies After gathering data about shark hunting techniques, the biologists reach to a conclusion that: They tend to pick off those seals that swim on the surface.

Baum et … Because the hunting behaviors of apex predators like sharks have trickle-down effects on the behavior of other marine species, they play a key role in maintaining healthy and balanced ecosystems. In an area of French Polynesia where as many as 900 sharks pack into a narrow channel, scientists have observed a new behavior: sharks hunting in … observed that white sharks near Seal Island, South Africa, attacked mostly around sunrise; one theory suggests that they are able to utilize the blinding effect of sunlight to their advantage while attacking from below and behind. Aim with your speargun, before pulling the trigger and shooting these sea predators! Many open ocean fishes and sharks exhibit 'yo-yo’ swimming patterns (repeatedly climbing and diving through the water while swimming), and scientists hypothesize this behavior might be linked to energy conservation, hunting or navigation.

Basking sharks, whale sharks, and megamouth sharks have independently evolved different strategies for filter feeding plankton: basking sharks practice ram feeding, whale sharks use suction to take in plankton and small fishes, and megamouth sharks make suction feeding more efficient by using the luminescent tissue inside of their mouths to attract prey in the deep ocean. Silky sharks are known for their quick and aggressive behavior, and have been seen performing threat displays in which they raise their head, arch their back, and lower their tail.
