The document describes several different animal species. It provides details about the average sizes, weights, lifespans and habitats of elephants, lions, tigers, leopards, jaguars, camels, whales, alligators, snakes and frogs. Key facts included are that elephants have the longest gestation period of any land animal at 22 months, lions currently only exist in Africa and India, and tigers can weigh up to 320 kilograms for males.

1. Elephant Elephants are mammals, and the largest land animals alive today. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (265 lb). An elephant may live as long as 70 years, sometimes longer. The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 12,000 kg (26,400 lb), with a shoulder height of 4.2 m (13.8 ft), a metre (3 ft 4 in) taller than the average male African elephant.

2. Lion The lion ( Panthera leo ) is a mammal of the family Felidae and one of four "big cats" in the genus Panthera . The lion is the second largest feline species, after the tiger. The male lion, easily recognized by his mane, weighs between 150–250 kg (330–500 lb). Females range 120–150 kg (260–330 lb). In the wild, lions live for around 10–14 years, while in captivity they can live over 20 years. Though they were once found throughout much of Africa, Asia and Europe, lions currently exist in the wild only in Africa and India. They enjoy hot climates, and hunt in groups.

3. Tiger Tigers are the heaviest cats found in the wild. Although different subspecies of tiger have different characteristics, in general male tigers weigh between 200 and 320 kilograms (440 and 700 lb) and females between 120 and 181 kg (265 and 400 lb). On average, males are between 2.6 and 3.3 metres (8 ft 6 in to 10 ft 8 in) in total length, and females are from nose to tip of tail between 2.3 and 2.75 metres (7 ft 6 in and 9 ft) in length. Of the living subspecies, Sumatran tigers are the smallest, and Amur (or Siberian) tigers are the largest.

4. White tigers are individual specimens of the ordinary orange tiger ( Panthera tigris ), with a genetic condition that causes paler colouration of the normally orange fur (they still have black stripes). The condition is well-documented in the Bengal tiger subspecies ( Panthera tigris tigris or P. t. bengalensis ), may also have occurred in captive Siberian tigers ( Panthera tigris altaica ), and has been reported historically in several other subspecies White Tiger

5. Leopard This spotted cat most closely resembles the jaguar physically, although it is of lighter build. Males can grow to weigh 91 kg (200 lbs) and the females can weigh 60 kg (132 lbs). Largely nocturnal and arboreal predators, they are opportunistic and versatile hunters

6. Jaguar The jaguar is a compact and well-muscled animal. There are significant variations in size: weights are normally in the range of 56–96 kilograms (124–211 lb ). Larger animals have been recorded as weighing 131–151 kilograms (288–333 lb) (matching the weight of the smallests lions and tiger females), and smaller ones have extremely low weights of 36 kilograms (80 lb). Females are typically 10–20% smaller than males. The length of the cat varies from 1.62–1.83 meters (5.3–6 feet), and its tail may add a further 75 centimeters (30 in). It stands about 67–76 centimeters (27–30 in) tall at the shoulders. [

7. Camel They are native to the dry and desert areas of western Asia and East Africa, and central and east Asia, respectively. The average life expectancy of a camel is 50 to 60 years. A fully-grown adult camel stands 1.85m/6 feet at the shoulder and 2.15m/7 feet at the hump. The hump rises about 30 inches out of its body. Camels can run up to 40mph in short bursts, and sustain speeds of up to 25mph.

8. Whale Whales breathe through blowholes, located on the top of the head so the animal can remain submerged. The shapes of whales' spouts when exhaling after a dive, when seen from the right angle. Whales have a unique respiratory system that lets them stay underwater for long periods of time without taking in oxygen. Some whales, such as the Sperm Whale, can stay underwater for up to two hours holding a single breath. The Blue Whale is the largest known mammal that has ever lived, and the largest living animal, at up to 35 m (105ft) long and 150 tons. Whales generally live for 40-200 years, but it is rare to find one that lives over a century.

9. Alligator An average American alligator's weight and length is 800 lbs. and 13 feet long. The largest alligator ever recorded measured 19 feet 2 inches (5.8 meters) and was found on Marsh Island, Louisiana. Few of the giant specimens were weighed, but the larger ones could have exceeded a ton in weight. The Chinese Alligator is smaller, rarely exceeding 7 feet (2 meters) in length. An alligator's lifespan is usually estimated in the range of 50 years or more. A specimen named Muja has resided in the Belgrade Zoo in Serbia since 1937, making it at least 70 years old. And in Riga Zoo, Latvia an alligator has been living since 1935.

11. Frog The distribution of frogs ranges from tropic to subarctic regions, but most species are found in tropical rainforests. Consisting of more than 5,000 species described, they are among the most diverse groups of vertebrates. However, populations of certain frog species are significantly declining.
