Today the blue whale is not only the biggest animal in the world, but also the biggest animal, ever existing on the planet Earth. There is a hypothesis that the herbivorous dinosaur from group zauropod Amfitseliya is the largest animal who is nearly 10 meters longer than a whale, but his existence is not proved.
Instruction
1. The died-out Amfitseliya's dinosaur is described by a fragment of the unique half-ruined vertebra therefore its sizes and existence of this dinosaur under doubt. By calculations length was it from 40 to 62 meters, and weight to 155 tons. Scientific classification: the kingdom – animals, type – chordates, a class – prsmykayushchiyesya, group – yashcherotazovy, infraotryad – zauropoda, a semestvo – diplopoida, a sort – amphicoelias.
2. The blue whale – a marine modern animal which length reaches 33 meters and weight can exceed 150 tons. Scientific classification: the domain – eukariota, the kingdom – animals, type – chordates, a class – mammals, group – cetacea, family – polosatikovy, a sort – fin whales, a look – a blue whale. It eats plankton filtered through lamellar baleen: the krill is the cornerstone of food, larger crustaceans, small are more rare than the slave and cephalopods. Allocate four subspecies of a blue whale – northern, southern, dwarfish and Indian. They slightly differ in the sizes and latitudes of dwelling. The blue whale meets in all World Ocean. Whales seldom form small groups, single individuals meet more often. By 1960 thanks to whaling the blue whale appeared on the verge of total disappearance. Today their total number does not exceed 10,000 individuals. At a blue whale of a female is much larger than males, there is an opinion that whales (blyuvala) were larger than modern individuals earlier. Sight and sense of smell at them bad. Hearing and touch are well developed. The weight of language is 4 tons, and the size of a throat is only 10 cm in the diameter. The volume of lungs exceeds 3 thousand liters. Large individuals the volume of blood have over 8 thousand liters. Heart of a blue whale the biggest in all fauna and its weight makes about one ton, and pulse of 5 - 10 beats per minute. Females give birth 1 time in 2 years, and pregnancy lasts 11 months. However gain of population cannot compensate its decrease. The born kid weighs about 2-3 tons and in length reaches 6-8 meters. The cub eats milk of mother of 7 months and grows to 16 meters for this term. Whales reach a physical maturity by 15 years, and live up to 80 – 90 years.
3. An overland largest animal it is considered to be the African elephant today. The maximum registered weight was 12.24 tons, and height in shoulders of 3.96 meters. Scientific classification: the domain – eukariota, the kingdom – animals, type – chordates, a class – mammals, group – hemipterous, family – elephant, a sort – the African elephants. Live in herds up to 100 individuals led by mature females. Males keep one by one. The upper lip at elephants grew together with a nose and the unique body – a trunk was formed. With its help the elephants breathe, drink, get food, express emotions, get rid of parasites, protected and bathe. Herbivorous elephants, a day one elephant eats about 100 kg of a grass, a bush, roots and branches of trees. Today war is declared on poaching as the number of elephants promptly decreases. Are widespread throughout Africa. Reproduction is not connected with seasons, pregnancy lasts 22 months. One female gives birth to about 9 elephant calves for all life. The newborn elephant calf weighs about 100 kg, reaching 1 meter in shoulders. Polovozrelosti is reached by 12 – 20 years, and there live about 70 years.
