Scientists prove shark-on-shark attacks in Mossel Bay

Posted on 29 June 2023 By Lisa Abdellah

Worldwide, reports of shark-on-shark attacks are on the rise. Now, off South Africa’s dramatic southern coast, a new hotspot has emerged — in Mossel Bay. Off the coast near Seal Island where great white sharks are known to chase and capture the furry mammals with breach-the-surface aeronautics, scientists have come upon a new theory as to what makes up most of the great white shark’s diet — and it’s not seals.

In a ground-breaking investigation shown in National Geographic’s Shark Eat Shark (part of SHARKFEST, which premieres on Saturday 1 July at 6:45 pm), scientists Enrico Gennari and Lacey Williams embark on a factual voyage with the help of Neil Hammerschlag to solve this predator-prey mystery, by casting a wide net of scientific experiments across the bay. The pair use camera tags and baited remote underwater vehicles (or BRUVs), skin samples and more, to try and capture concrete evidence that sharks are preying on other sharks. With a target area locked in as their playing field for the search, everything starts off promising. But even though the team believes they have every angle of the investigation covered, nature throws them curveball after curveball that threatens to jeopardise everything. 

In the end, the team perseveres against all odds and is left with the first-ever evidence of their theory that life in the waters of Mossel Bay is a Shark Eat Shark world.

With cutting-edge technology and industry-leading experts, SHARKFEST will entertain you with four weeks of explosive, hair-raising and celebratory shark programming that will showcase the captivating science, power and beauty of these magnificent animals — because one week is simply not enough. With over 22 hours of original programming and over 50 hours of enhanced content, you’ll be able to dive deep into the unpredictable psyche of sharks and their remarkable lives. 

SHARKFEST will also explore the waters across the US in Cape Cod, Florida, Hawaii, New York, South Carolina, and worldwide in Australia, the Bahamas, Canada, Indonesia, the UK and more for a global underwater adventure.  

Continuing its partnership with Minorities in Shark Sciences (MISS), which encourages diversity and inclusion in shark sciences and inspires the next generation of scientists, National Geographic’s SHARKFEST will feature new and familiar experts in this year’s programming. This collaboration lends MISS experts as on-screen talent and allows them to be consultants for the programming and development of the series.
