What is a gray whale?
Gray Whale, Eschrichtius robustus is a migration whale that maintains the population in the eastern and west coastal Pacific Ocean. The third population once existed in the North Atlantic Ocean, but disappeared to move. Gray whales spend most of their lives by traveling between breeding areas in winter and summer feed.
genetically related to blue whales and humpback whales, the gray whale is clear in its gray and white coloring and lack of dorsal fin. Although dark gray color, the whales are marked with white scars that remained parasites. Adult male animals have a length of about 45-46 ft (13,7-14 m) and weigh about 30-40 tons (27,200-36 300 kg.) Women are slightly larger than men. Newborn calf has about 15 ft (4.5 m) long and usually weigh between £ 1,000 and £ 1,500 (£ 500-680)
The California Gray Whale of the Eastern Pacific maintains a predictable migration formula, followed by a closely whabousing of fans. In October each year the whales float south of the Alaskan areaI, on average 80 miles a day (120 km) to March, most of the population reaches Baja in California, where there are lagoons of gray whales. In these protected lagoons, the whales shake and give birth until April or May before their northern trek starts back to the Alaska feed area. The annual journey is 10,000 to 14,000 miles (16,000-22 530 km) long, which is assumed to be the longest mammal mammal mammal formula.
Gray Whale mothers travel with their newborn calves after children have created sufficient layers to keep them in colder waters. A trip to the north is dangerous for calves because sharks and whales are actively hunting. Whale mothers are recorded as especially aggressive protectors who originally lead to classified as dangerous and commonly called "Devilian fish".
History of human interaction with gray whales is not pleasant, with a whaler being a keyby the extension of the extinction of the Atlantic populations. When the calving of Baja Lagoon, breeding and midwives were killed for the first time in 1857, was killed by hundreds. In 1949, the International Commission for Whale (IWC) banned commercial hunting of gray whales and the Eastern Pacific population was recovered, despite the continuing hunting of some indigenous American and Russian groups. The population of the Western Pacific believes that experts will remain in a critical danger of extinction, surviving only 100-300 animals.
The survival of gray whales is based mainly on the preparation of whales as a protected species. Great monitoring groups and animal rights continue to emphasize the importance of ensuring survival of acid creatures within the ocean food chain. Due to the huge recovery of the California population of gray whales, IWC Hjak faces assembly pressure to allow commercial hunting animals again. Although the gray whale flourishes again in the coastal waters of North America, its future remains uncertain as a result of huntinglegislation and possible climate change.
