An orca, a killer whale, is believed to have killed two white sharks found washed ashore at Frankskraal near Gansbaai this week.
The first is a female shark nearly 5m long.
Marine biologist, Allison Towner says this is the fifth white shark carcass and the largest to wash up in Gansbaai since 2012.
On examining the shark, biologists found her liver was missing.
Previously recorded behaviour, seems to point to them being the cause.
We were joint experts, and his opinion was that yes it is quite conclusive given the fact that a liver is missing that it could well be contributed to orca.— Allison Towner, Marine Biologist at the Dyer Island Conservation Trust
They are known to specialise on very sharp species for particularity the liver, the liver is a very oily organ and very nutrient dense, and it seems they are quite a connoisseur when it comes to predatory behavior with sharks.— Allison Towner, Marine Biologist at the Dyer Island Conservation Trust
