How deep do right whales dive?

Right whales typically dive to depths of about 40 to 50 meters (131 to 164 feet) while foraging for food, although they can occasionally reach depths of up to 70 meters (230 feet). Their dives usually last around 10 to 15 minutes, but they can be longer depending on the availability of prey. Unlike some other whale species, right whales are not known for deep or prolonged dives.
