Regarding diving for food, the amount of time a blue whale dives generally last around 10 minutes, although these whales have been recorded staying submerged for up to half an hour.
Why do blue whales live in cold water?

How big do blue whales get?
However, a few species of krill can grow close to 6 inches in size. Compared to the small size of krill, the blue whale can grow to be more than 100 ft. long (60 – 80 ft. on average) and weigh over 180 tons (100 – 150 tons on average)!
