Orca Attacks on Great White Sharks Threaten Species

An unsettling trend of orca attacks on great white sharks has been observed, shedding light on the 'Hannibal Lecter' phenomenon in the marine world. Recently, a 4.7-meter great white shark carcass washed ashore in Portland, Australia, with a 50-centimeter incision revealing only the missing liver and a few organs.

Eye witnesses reported a group of orcas launching an assault on a great white shark a few days earlier, a behavior uncommon as orcas are typically seen preying on seals. DNA analysis of the bite marks confirmed the involvement of orcas.

Similar incidents have been reported globally, including an attack in South Africa where a great white shark's belly was torn open with the liver missing. The decrease in great white shark sightings in South Africa has been attributed to the presence of two resident orcas in the region.

Isabella Reeves from Flinders University notes that the 'Hannibal Lecter' phenomenon is becoming more prevalent, speculating that orcas target the liver due to essential nutrients it provides. The liver constitutes a significant portion of a shark's body, making it a desirable prey for orcas.

Known as the 'wolves of the sea', orcas are notorious for their group hunting behavior and preference for shark livers, as well as whale tongues. The great white shark, classified as 'vulnerable' by the World Wildlife Fund, plays a crucial role in maintaining marine ecosystem balance.
