The blue whale, Balaenoptera musculus<\/em><\/a>, is the largest animal ever to have lived on Earth. Depending on which expert is cited, blue whales once attained lengths of 100 to 120 feet (32 meters) and have weighed up to 160 tons (145 metric tonnes). Blue whales are found throughout the worlds oceans. Estimates put their worldwide population at approximately 10% that of prewhaling size, and blue whales are listed as endangered throughout their range. The population of blue whales in the Southern Ocean was hunted especially hard.<\/p>\n

Two of the images above show blue whale pairs likely composed of a mother with calf\/subadult. Blue whale calves will accompany their mothers for approximately a year before being weaned. Female blue whales are larger than males, an adaptation enabling a mother to cope with the physical demands of calving and nursing.<\/p>\n

Blue whales are most easily identified by their huge size, tall blows (up to 30 feet high), blue\/gray mottled skin color, and typically rounded (falcate) dorsal fin. Skin pigment patterns along the dorsal ridge, near the dorsal fin, are photographed by scientists in order to identify individual whales. The tips of a blue whale’s fluke are rather pointed, and the trailing edge of the fluke is usually smooth and straight with a median notch. Blue whales are closely related to fin whales (Balaenoptera physalus), which are also huge, but the body of a blue whale is mottled and lighter in color and its dorsal fin is not as tall and pronounced as that of the fin whale. Also, the right lip and baleen plate of the fin whale is light colored and the underside of its body is white. (Blue and fin whales are thought to occasionally interbreed (Calambokidis)). Seen from a distance, blue whales resting or swimming just below the surface appear to be large sandbars.<\/p>\n

Scientists estimate that the largest blue ever to have lived probably weighed more than 200 tons — 400,000 pounds — and was more massive than an entire herd of thirty African elephants. A truly impressive beast, indeed. Blue whales dwarf even the largest dinosaurs, being nearly twice the size of the largest prehistoric land dweller Brachiosaurus. A small child could crawl through the chambers of a blue whale’s immense heart, or out one of its twin blowholes. Scientific accounts cite individual blue whales nearly 100 feet in length while less reliable whaling records reported giants up to 110 feet long. The largest subspecies of blue whale, intermedia, inhabits Antarctic regions while the slightly smaller musculus is found in northern hemisphere oceans.<\/p>\n

Do blue whales socialize? Of course! But how they find one another across miles of ocean, what brings them together, and what they do when in one another\u00c3\u201a\u00c2\u00b4s company is still largely a mystery. Researchers around the world are gradually coming to understand the life of this greatest of whales through direct observation, remote sensing with satellite tags, and by eavesdropping on whale vocalizations with sophisticated hydrophones.<\/p>\n

All of the above photographs are of blue whales in the eastern North Pacific stock, a population that ranges from Baja California to at least as north as Oregon. Whales from this stock are often seen migrating north along the Pacific coast in spring and summer, typically stopping near Point Conception or the Farallon Islands to feed on aggregations of krill in August and September.
