How deep can a fin whale dive?

The fin whale is capable of dives up to 2,200 metres (7,200 feet), making it one of the deepest diving marine mammals. During these deep dives, which can last for up to 90 minutes, fin whales slow down their respiration rate and maintain neutral buoyancy by adjusting their internal gas volumes. These impressive capabilities allow them to access deep-sea resources like squid and krill. Scientists studying these animals rely on various methods, including acoustic tags and depth sensors attached to individuals to gain insights into their diving behavior and deep-sea foraging strategies.
