Pliosaurus Flippers and Swimming Mechanics

The video explores how large predators like the pliosaurus, a 45-foot-long creature, manage to catch their prey. It draws parallels with penguins, which use their flippers to achieve high speeds underwater. Biomechanics expert Flavio Noca uses high-speed cameras to study penguin movement, revealing that they flap their wings like birds to propel themselves. The pliosaurus, with its four large flippers, was likely one of the fastest ocean predators. Aerospace engineer Luke Muscat uses x-rays and dye experiments to understand how the pliosaurus's flippers worked together to generate significant thrust and acceleration, making it a formidable hunter.

What is the main challenge for a large predator like the pliosaurus in catching its prey?

• Hiding from prey
