Can a great white shark kill a Megalodon?
The great white shark (Carcharodon carcharias) may have wiped out the giant megalodon (Otodus megalodon). But scientists may have miscalculated megalodon’s time of death by about 1 million years. The researchers in the new study suggested that the huge sharks were outcompeted by a smaller, savvier predator.
Do sharks really die if they stop moving?
Instead, these sharks rely on obligate ram ventilation, a way of breathing that requires sharks to swim with their mouths open. The faster they swim, the more water is pushed through their gills.
