Study Notes
- Male sharks are often presumed to be dominant, but the biggest, baddest, and fiercest sharks in the ocean are females.
- Female great white sharks can grow over 21 feet in length and weigh around two tons, needing to be larger to reproduce successfully.
- Pregnant female great white sharks can carry as many as 17 live young in utero, each measuring up to five feet long.
- Female great white sharks may be more voracious than males, possibly seeking out food in coastal zones due to physiological demands during pregnancy.
- Researcher Allison Towner tracks large female white sharks to uncover their movements and behavior in real time using acoustic transmitters.
- A team of scientists is studying shark personalities, with a focus on understanding the behaviors of bull sharks and tiger sharks in different contexts.
- Large female sharks, like female great whites and tigers, may exhibit dominance over males and show various levels of confidence and behavior towards humans.- Females are scoring higher than males in shark behavior studies.
- Marine biologist Eric Clua focuses on understanding shark behavior and human-shark conflict.
- Clua's theory suggests that sharks have individual personalities, with some being problem individuals that may attack humans.
- The behavior of problem individuals is believed to be linked to genetics, experience, and environment.
- Genetic analysis is used to identify potential problem individuals in shark populations.
- DNA sampling is done through less intrusive methods like collecting saliva samples.
- Tracking and studying individual shark behaviors help in understanding their unique personalities.
- Female sharks, especially the larger ones, exhibit dominance and unique behaviors.
- Pregnant female sharks may exhibit different behaviors, focusing on birthing rather than feeding.
- Researchers work on identifying dominant sharks to potentially understand problem individuals better and improve human-shark coexistence.
