The answer to that question definitely depends on the species (as well as the individual). One of the most impressive of all diving cetaceans is the sperm whale (the species with a large rectangular head). You can hold your breath for about 90 minutes as you dive to depths of over 3,000 feet to feast on your favorite food, giant squid.However, the sperm whale is not the only impressive cetacean diver. The blue whale (the largest animal that ever lived) can hold its breath for up to 90 minutes and usually reappears after about 30 minutes; The deepest dive ever recorded for a blue whale was around 1,000 feet below the surface.
