Blog Article
Inside the wide and mysterious depths with the ocean, two apex predators reign supreme—killer whales (orcas) and excellent white sharks. While both equally are recognized for their dominance in the marine food stuff chain, latest proof has shown that orcas are not simply competing with great whites but actively searching them. But How come killer whales attack wonderful white sharks? Enable’s dive in to the science guiding this fascinating predator fight.
The Increase of Orca vs. Shark Encounters
For many years, fantastic white sharks ended up considered the undisputed kings in the ocean. However, in recent times, marine biologists have documented many incidents where pods of orcas have hunted and killed excellent white sharks, specifically off the Coastline of South Africa, California, and Australia.
The most famous conditions occurred in 2017 in the vicinity of South Africa, when scientists identified quite a few great white sharks washed ashore with their livers lacking, a telltale indicator of orca predation. Since then, similar designs are noticed in other areas, foremost researchers to research why these attacks are happening a lot more usually.
How come Killer Whales Concentrate on Terrific White Sharks?
The Nutritional Worth of Shark Livers
