The trevally are capable of leaping from the water and calculating the air speed, altitude and trajectory of the tern, catching the prey in mid air, before devouring it beneath the surface. Trevally are predators in and out of the ocean (Photo: BBC) In episode one this takes place between the monstrous trevally and a baby tern. Trevally can calculate air speed, altitude and trajectory of preyĪ David Attenborough documentary wouldn’t be complete without a nerve-jangling battle of wits between predator and prey. In its lifetime a large storm can release energy via waves that is the equivalent to 10,000 nuclear bombs. It isn’t just creatures that are under the microscope in Blue Planet II – the immense power of waves are also examined.
