In summer months they move about in cold water seeking foraging areas where there are large concentrations of krill. details, Antarctica travel deals and last minute relationships. B sounds are made by both sexes and seem to occur in feeding areas. If they were kept in aquariums, they would require extremely intensive care. Forty-eight blue whales were landed at Central California shore whaling stations as late as 1965. Site Map | Another adaptation whales developed to protect themselves is related to size. Whales are some of the most fascinating and majestic creatures in the animal kingdom. Some of the more common behaviors observed in belugas include tail-slapping, breaching, spyhopping, and bubble blowing.
