Sperm Whale Facts (cachalot)
), also called the brimstone whale, the most massive animal that ever lived, a solitary cetacean species that weighs approximately 150 tons and can reach a length of more than 30 meters (98 ft). The largest blue whale accurately measured was a female 29.5 meters long and weighing 180 metric tons (about 200 short [US] tons), but there are reports of a 33-meter catch that may have reached 200 metric tons. The heart of a blue whale has been recorded to weigh about 700 kilograms (about 1,500 pounds).
The blue whale is a cetacean and is scientifically classified in the order Cetacea as a rorqual (family Balaenopteridae) related to gray whales (family Eschrichtiidae) and right whales (Balaenidae and Neobalaenidae) of the baleen whale suborder, Mysticeti.
Blue whales have a blue-gray color with lighter gray spots in the form of large spots, which look as if they were painted with a large brush. The lower surfaces of the feathers are in some cases lighter gray or white. The blue whale is called the sulfur-bottomed whale because of the yellow underside of some individuals resembling the pale yellow color of that chemical element; this color is given by some algae (diatoms) that live in the whale’s body. The blue whale has a broad head, a small dorsal fin located near the hump, and 80-100 long tufts running along the throat and chest. Its mouth contains up to 800 plates of short, broad, black whalebone or “whale bone”, with thick, coarse hairs used to catch food. Females are generally larger than males, and the largest animals live in the Southern Ocean around Antarctica.
The blue whale is found singly or in small groups in all oceans, but southern hemisphere populations are much larger. In the Northern Hemisphere, blue whales can be seen regularly in the Gulf of St. Lawrence and off the coast of Monterey, California and Baja California, Mexico. They spend the summer in polar waters, feeding on shrimp-like shrimp called krill. During a dive, the blue whale can engage in a series of 360° twists and turns to locate prey and quickly reorient its body to hold large concentrations of fins in an open-mouth dive. An adult blue person can consume up to eight tons of wings per day. In winter, blue whales move to the equator to breed. After a gestation period of about 12 months, a calf about 8 meters (about 26 feet) long is born in the freshwater. During lactation, calves gain up to 90 kilograms (about 198 pounds) a day on their mothers’ rich milk. The cubs are weaned after seven to eight months, when they reach a length of about 15 meters (about 49 feet).

Once the most important of the commercially hunted single whales, the blue whale was greatly reduced in numbers in the first half of the 20th century. Only in the 1930-1931 season. the number of blue whales in the world exceeded 29,000. This species has been protected from commercial whaling since the mid-1960s. The blue whale population appears to be recovering and is estimated at between 10,000 and 25,000 animals worldwide. However, the International Union for Conservation of Nature still lists the blue whale as an endangered species. The blue whale, a feeder or filter whale, unlike toothed whales, inhabits the waters of the Channel Islands National Park and the Channel Islands National Sanctuary. It is the largest animal proven to have ever existed on earth. With feeding grounds for this species located off the coast of Southern California, the public is given a unique opportunity to view these remarkable marine mammals on the whale watching boats that service the area.
By Jefferson, T.A., S. Leatherwood and MA. Weber, “The blue whale is the largest animal ever known; however, its size largely overlaps that of fin whales and sejkits. Like all rorquals, the blue whale is thin and simple. The head is broad and U-shaped when viewed from above from the side (A-shaped). the long center of the pulpit, has a projecting crest, terminating in a striking “splashguard” around the opening. The fins are long and pointed, and the dorsal fin is relatively small, variable in shape, and located about three-quarters of the way back from the tip of the snout. Flux blue have a relatively straight edge with a straight edge. ally and something lighter below. The head is solid blue, but the back and sides are washed out. When viewed through the surface of the water, they may appear mottled or uniformly light blue. There are light to broad spots on the sides, back and belly, usually in the form of dark spots on a lighter surface, but sometimes vice versa. A chevron, with the tip behind the holes, sometimes marks the transition of color between the head and the body. The throat has 55 to 88 long folds that extend to or near the umbilicus. The mouth contains between 270 and 395 pairs of black, wide Balinese plates, each less than 3 meters long. The plant is tall and slender, reaching a height of 30 feet or more.”
Based on studies of acoustic data, size and photographic identification, there are two groups of blue whales in the North Pacific: eastern and western. The eastern group, (which is the west coast of the US and Canada), winters near Mexico and Central America and forages from California and British Columbia in the summer/fall (June to November).
According to the Channel Islands National Marine Sanctuary, “blue whales can be seen off the west coast of Baja California from February to July. The largest number there was recorded in April. They reappear in the area in October but are not reported between November and January. They are quite common in southern California from June to December. Encounters occurred only from the north from July to October. Most meetings were only from July to October. nnel islands Catches of blue whales from coastal stations in British Columbia peaked in June and September, showing a northward movement past Vancouver Island in the spring and a southward movement in the fall.
The Largest Heart In The Animal Kingdom Belongs To The Blue Whale
The habitat of the blue whale, as reported in a 1998 study by the Southwest Fisheries Science Center, NOAA, shows that the relationship between this species and its habitat coincides with the movement of food resources as well as migration due to its reproductive imperative. The main feeding habitat, as reported on Miga Island and San San Island, is reported to be the Channel Islands and the adjacent continental shelf. There is also a large pool of krill and other food sources for this species.
Additional habitat focuses on the reproduction process. This species migrates in southern climates, based on observations, as far north as the Gulf of Cortez in Baja California and as far south as Central America, where the initial growth of newborn calves provides optimal conditions. However, the specific location of areas where blue whale mother activity occurs is still unknown.
Goldbogen (Scripps Institution of Oceanography) described a unique feeding technique used by blue whales called “digging”. This efficient method, the study noted, detailed how the adaptation of the whale’s jaw allowed for maximum opening, which in turn allowed the blue whale to retreat and capture the largest concentration of food. After catching the prey, the water is taken out with the tongue, and animals such as krill filter the whale and remain as food for the whales.
The main food of the blue whale in the California Channel Islands is krill, which are small shrimp-like shrimps. Three types of krill make up this important food in the blue whale’s diet. They are North Pacific krill (
Sperm Whales Have The Biggest Brains, But How Smart Are They?
Information from the Marine Mammal Center states: “Females give birth to calves every two to three years. They are pregnant for about a year before giving birth. When born, a blue whale calf is about 23 feet long and weighs 5,000 to 6,000 pounds. A nursing blue whale mother provides 5 to 50% of the milk per day and 5 to 50% of the milk per day.
