Whales exhibit the same respiratory patterns, blowing three to five times every fifteen to thirty seconds. They then raise their flukes and go under the water for about three to five minutes. Grey whales eat off the bottom of the ocean. They suck mud and amphipods from the sea floor, then they swallow the food and spit out the water and mud. When a whale is under the water, it beats its tail and a column of water rises to the top and leaves a smooth patch on the surface.
Grey whales are very friendly and they like to get patted.
