5.The ants don't sleep. They have colonised almost every landmass on Earth.

6.Some Albatrosses have blue feets. They live just in Gallapagos.

Skin is the human body’s largest organ.

Our brain is programmed to erect the inverted image formed on our retina by the convex eye lens. A newborn baby sees the world upside down till its brain starts erecting it.

You are about 1cm taller in the morning when you first get up than when you go to bed. This is because during the day the soft cartilage between your bones gets squashed and compressed.

You carry, on average, about four pounds of bacteria around in your body.

In case of injury under the skin the blood vessels break and spread into the tissues near the injury. The dark colour of the blood shows through the skin as bruise.

There are approximately 96,000 km / 59650 miles of blood vessels in the human body.

The brain doesn’t feel pain; even though the brain processes pain signals, the brain itself does not actually feel pain.

The tooth is the only part of the human body that can’t repair itself.

Your nose can remember 50,000 different scents and women are better smellers than men.

Typically, the lion inhabits grasslands and savannas, but is absent in dense forests. It is usually more diurnal than other big cats, but when persecuted it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa, Southeast Europe, and Western and South Asia but today it has been reduced to fragmented populations in sub-Saharan Africa and one critically endangered population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in contemporary films and literature. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions were prominent in Ancient Egypt, and depictions have occurred in virtually all ancient and medieval cultures in the lion's former and current ranges.

      Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own.

       The tiger once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin, and in the south from the foothills of the Himalayas to Bali in the Sunda islands.
     10 facts about tigers:

1. Tigers are nocturnal animals The reason behind this is that Tigers prefer avoiding human conflict during daylight and also patrol around their territory at night.

2. Tiger cubs are born blind and only half of the cubs survive
The saddest part is that Tiger cubs are born blind and only a few survive. Literally, the newborn cubs can't see anything, they only follow the scent of their mother. Since they are born blind and can't keep up, most of them die of hunger or cold. Some even get eaten by male Tigers to make the Tigress available for mating.
3. Tigers love to swim and play in the water
Unlike the domestic cats, its larger version enjoy spending time in the water and they love to swim for hours. Since cubs, female Tigers encourage or help learn the art of hunting, they even have the ability to kill in the water. And as adults, it is said that they can swim for several kilometres and even have reported one to swim for 30 km in just a day.
4. Tigers live for about 25 years
The life expectancy of Tigers is between 20-25 years whether they are kept in captivity or in the wild.
5. Tigers can mate with other big cats
Tigers can also mates with other big cats, for example, if a male Tiger mates with female Lion, the hybrid born animal is known as Tigon. They are the largest cat species and can grow bigger than Liger which is a mix breed of male Lion and female Tiger. The height of a Liger is about 4.5 feet while on all four legs and about 6 feet tall when standing.
6. Tigers have antiseptic saliva
They tend to lick the area in order to prevent any infection.
7. Tigers can sprint at over 60 kilometre/hour
8. Tigers urine smells like buttered popcorn
9. Tigers can imitate the call of other animals
10. A tiger’s roar can be heard as far as three kilometres away

Parrots, along with ravens, crows, jays, and magpies, are among the most intelligent birds, and the ability of some species to imitate human speech enhances their popularity as pets. Trapping wild parrots for the pet trade, as well as hunting, habitat loss, and competition from invasive species, has diminished wild populations, with parrots being subjected to more exploitation than any other group of birds. Measures taken to conserve the habitats of some high-profile charismatic species have also protected many of the less charismatic species living in the same ecosystems.

Melanism in the leopard is conferred by a recessive allele.^[5] Melanistic and non-melanistic animals can be littermates. It is thought that melanism confers a selective advantage under certain conditions since it is more common in regions of dense forest, where light levels are lower. Preliminary studies also suggest that melanism might be linked to beneficial mutations in the immune system.^[6] The typical spotted markings are present but hidden due to the excess black pigments, which is called "ghost rosettes".^[7]

In North Africa, dark African leopards (P. p. pardus) were reported in the Atlas Mountains.^[8] A black leopard was sighted in the alpine zone of Mount Kenya.^[9] In 2019, a black leopard was recorded in Kenya's Laikipia County.^[10][11]

Frequency of melanism appears to be approximately 11% over the leopard's range. Data on the distribution of leopard populations indicates that melanism occurs in five subspecies in the wild: Indian leopard, Javan leopard, African leopard, Indochinese leopard (P. p. delacouri) and Sri Lankan leopard (P. p. kotiya). Based on records from camera traps, melanistic leopards occur foremost in tropical and subtropical moist forests.^[12] Melanistic leopards are common in Java, and are also reported from densely forested areas in southwestern China, Myanmar, Assam and Nepal, from Travancore, and some parts of southern India where they may be more numerous than spotted leopards. Most leopards recorded at 16 sites south of the Kra Isthmus between 1996 and 2009 were black, indicating a near fixation of melanism in peninsular Malaysia.^[13]

The cat is similar in anatomy to the other felid species: it has a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. Its night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling and grunting as well as cat-specific body language. A predator that is most active at dawn and dusk, the cat is a solitary hunter but a social species. It can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small mammals.^[7] It secretes and perceives pheromones.^[8]

Female domestic cats can have kittens from spring to late autumn, with litter sizes often ranging from two to five kittens.^[9] Domestic cats are bred and shown at events as registered pedigreed cats, a hobby known as cat fancy. Failure to control breeding of pet cats by spaying and neutering, as well as abandonment of pets, resulted in large numbers of feral cats worldwide, contributing to the extinction of entire bird, mammal, and reptile species, and evoking population control.^[10]

Cats were first domesticated in the Near East around 7500 BC.^[11] It was long thought that cat domestication was initiated in ancient Egypt, as since around 3100 BC veneration was given to cats in ancient Egypt.^[12][13] As of 2021 there are an estimated 220 million owned and 480 million stray cats in the world.^[14][15] As of 2017, the domestic cat was the second-most popular pet in the United States, with 95 million cats owned.^[16][17][18] In the United Kingdom, around 7.3 million cats lived in more than 4.8 million households as of 2019.^[19]

The rose-ringed parakeet is sexually dimorphic. The adult male sports a red and black neck ring, and the hen and immature birds of both sexes either show no neck rings, or display shadow-like pale to dark grey neck rings. Both sexes have a distinctive green colour in the wild, and captive bred ringnecks have multiple colour mutations including blue, violet and yellow. Rose-ringed parakeets measure on average 40 cm (16 in) in length, including the tail feathers, a large portion of their total length. Their average single-wing length is about 15 to 17.5 cm (5.9 to 6.9 in). In the wild, this is a noisy species with an unmistakable squawking call. Captive individuals can be taught to speak. They are a herbivorous and non-migratory species.

One of the few parrot species that have successfully adapted to living in disturbed habitats, it has withstood the onslaught of urbanisation and deforestation. As a popular pet species, escaped birds have colonised a number of cities around the world, including Northern and Western Europe.^[2] These parakeets have also proven themselves capable of living in a variety of climates outside their native range, and are able to survive low winter temperatures in Northern Europe.^[3][4] The species is listed as least concern by the International Union for Conservation of Nature (IUCN) because its population appears to be increasing, but its popularity as a pet and unpopularity with farmers have reduced its numbers in some parts of its native range.^[1]
