Auks in general are excellent swimmers and recent technology has made tracking the depth of their dives much easier.

Which animal can dive the deepest?

Cuvier’s beaked whales (Ziphius cavirostris) are master divers. These creatures hold the record for deepest plunge by a marine mammal. One whale dived to depths of nearly 3,000 meters (almost 1.9 miles). This species also holds the record for the longest dives.

What is the fastest bird in the world?

A ‘stooping’ peregrine is undoubtedly the fastest flying bird, reaching speeds of up 200 mph. However, the stoop is gravity-assisted – more of a controlled fall – and is generally not considered as level flight (where they reach 40 mph). Many swift species reach high speeds during their display flights.
