Basking sharks are the second largest fish in the world, reaching lengths of up to 10m (33ft). Until now, they have previously had a reputation for being slow and languid as they scour the sea for their staple diet of plankton.
However, a new study, recently published in leading international journal Biology Letters used video analysis for both species and estimated their vertical swimming speeds at the moment at which they left the water. Furthermore, they attached a data recording device to one large basking shark to measure its speed and movement, and also to store video footage.
Point - Seconds - Beats - Tail - Basking
At one point, in just over nine seconds, and with 10 beats of its tail, the basking shark accelerated from a depth of 28 m to the surface and broke through the water at nearly 90 degrees. The shark cleared the water for one second, and its leap peaked at a height of 1.2 m above the surface.
To achieve this breach, the basking shark exhibited a six-fold increase in tail beat frequency and attained a top speed of approximately 5.1 m/s. To put this into perspective, this is more than twice as fast as the average competitor...
