Blue Whale Photos - Images of the World's Largest Marine Mammal

Top Right Solid Corner

The blue whale, Balaenoptera musculus, is the largest mammal to ever inhabit the ocean. The largest recorded was a 108-foot adult female caught in Antarctica. Blue whales in the southern hemisphere reach lengths of 90 to 100 feet, but in the northern hemisphere they are smaller, on average 75 to 80 feet . Females are larger than males of the same age, the largest weighing as much as 150 tons, with an average of 100 tons. The blue whale is listed as endangered on the IUCN Red List of threatened species. The total world population was estimated to be between 5,000 and 12,000 in 2002, although there are high levels of uncertainty in estimates for many areas. As global warming causes glaciers and permafrost to melt and allow fresh water to flow into the oceans, there are concerns that there will be a disruption in the circulation of warm and cold water around the world. The blue whale's migratory patterns are based on ocean temperature. The whales summer in the cool latitudes, where they feed in krill-abundant waters, and winter in warmer latitudes, where they mate and give birth. The change in ocean temperature would also affect the food supply as the warming trend and decreased salinity would cause a shift in krill location and abundance.
