In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
Apex predator emerges as boaters stare in awe at fish’s ‘massive bite marks.’ See it ... The apex predator is the “fastest shark in the ocean,” able to reach speeds of around 40 mph.
An aerial apex predator, the great skua is an also an aggressive kleptoparasite, deliberately harassing birds as large as gannets to steal a free meal. It also readily kills and eats smaller birds such as puffins. Great skuas show little to no fear of humans – anybody getting close to the nest will be repeatedly dive-bombed by the territorial ...
