Blue diet whale
It is not known how long traveling pairs stay together. Due to excessive hunting the population significantly declined over the decades. 6 m (110 feet). Antarctic is the main hub of these animals, hosting more than 230,000 whales. The blue whales weigh around 150-170 metric tons (170-190 short tons) together with ah length of about 27 m (89 feet). The pygmy blue whale formed from a founder group of Antarctic blue whales about 20,000 years ago, around the Last Glacial Maximum. These animals predominantly feed on krill, copepods, Meganyctiphanes norvegica, Thysanoessa raschii, Thysanoessa inermis, Thysanoessa longicaudata, Euphausia pacifica, Thysanoessa inermis, Thysanoessa longipes, Thysanoessa spinifera, and Nyctiphanes symplex. The largest blue whale ever measured at 190 metric tons (210 short tons), and the longest whales recorded at 33. When surfacing to breathe, the blue whale raises its shoulder and blowhole out of the water to a greater extent than other large whales, such as the fin or sei whales. There have been at least 11 documented cases of blue whale- fin whale hybrid adults in the wild. In locations where there is a high concentration of food, as many as 50 blue whales have been seen scattered over a small area. The weight of the blue whale heart is about 600 kg (1,300 lb). In order to breathe they rise to the water surface while emitting sprout up to 12 m (39 feet). Early in the twentieth century these whales were abundant in almost all waters of the Earth. Blue whales most commonly live alone or with one other individual. Blue whales were abundant in nearly all the oceans on Earth until the beginning of the twentieth century. 5 feet) when migrating in order to eliminate drag from surface waves. The blue whale lungs are capable to withhold 5,000 litres (1320 U. Between 70 and 118 grooves (called ventral pleats) run along the throat parallel to the body length.
Its U-shaped head coupled with baleen plates gives it an unmistakable appearance. 8-13 ft). The head covers 25% of their entire body length. S. The degree of mottling varies substantially from individual to individual. For over a century, they were hunted almost to extinction by whalers until protected by the international community in 1966. It is not known when the members of those families diverged from each other. This is likely because blue whales were driven north by expanding ice, and some have stayed there ever since. The length of the flippers measure around 3-4 metres (9. The head and tail fluke are generally uniformly grey. Blue whales typically swim at a depth of about 13 meters (42. Some blue whales in the North Atlantic and North Pacific raise their tail fluke when diving. These marine animals exhibit several bluish-grey shades together with a long willowy body. Observers can use this trait to differentiate between species at sea. Blue whales dive 100 m (330 feet) deep into the ocean in order to feed on krill. The blue whale (Balaenoptera musculus) is the largest marine animal with the weight of about 180 metric tons (200 short tons). gallons) of water. Blue whales are mostly found in the Pacific, Antarctic, North Atlantic, and Indian Ocean. These pleats assist with evacuating water from the mouth after lunge feeding (see feeding below). There are two more groups in the North Atlantic, and at least two in the Southern Hemisphere. These animals are found in an area where food is abundant.
