Stunning drone footage captured by a group of scientists has captured gigantic blue whales feeding off the southern coast of New Zealand.
The video gives an aerial insight into the feeding behaviour of the blue whale, the largest animal in the world.
The Oregon State University scientists say the whales pick and choose their meals to balance the energy gained through the food with the energy used to capture it.
"It would be like me driving a car and braking every 100 yards [91 metres], then accelerating again," expedition leader Leigh Torres says.
"Whales need to be choosy about when to apply the brakes to feed on a patch of krill."
The video shows a blue whale bypassing krill patches before targeting a specific large mass of krill.
