I agree, it is an eye catching title. The big deal at Isla Guadalupe is the science of this site. We KNOW they feed on E-seals, but have only seen in happen twice in 6 years out there. When you're on site for 12-16 weeks at a time that's an extremely low predation rate...so, what ARE they feeding on?
Turns out they are actively feeding on the much smaller Guadalupe Fur seals and that these attacks happen sub-surface so no one sees them. With an estimated population of close to 5 thousand fur seals on site this is one of the main reasons these sharks are here in such great numbers each season.
It many seem like something everyone should know, but that's why we are supporting the team from CICIMAR and UC Davis, to get the real data and understand a bit more about the "why".
