Whale

 Any of the bigger species of aquatic animals that belong to the Cetacea order. The name whale can refer to any cetacean, including porpoises and dolphins, but it is most commonly given to those that are longer than 3 metres (10 feet). The 2.7-metre tiny sperm whale (Kogia simus), which bears a striking likeness to its larger cousin, is an exception. Whales are the heaviest living or fossil creatures, with the blue whale (Balaenoptera musculus) reaching a maximum size of potentially more than 30 metres and 200 metric tonnes (220 short [US] tonnes.Except for the landlocked Caspian and Aral seas, whales can be found in all of the world's oceans and seas, from the Equator to the arctic ice. They are mammals with the following characteristics: they breathe air, are warm-blooded, give live birth, suckle their young with milk, and have hair. All are totally aquatic, with particular adaptations for living in water such as flippers and tail flukes. Whales must surface to breathe on a regular basis, allowing them to eject more air from their lungs than most mammals in an almost explosive breath known as a blow. The water vapor in the whale's hot breath condenses when the blow is released, making the blow visible.

              

Tiger

 The tiger (Panthera tigris), the largest member of the cat family (Felidae), is only surpassed in size and ferocity by the lion (Panthera leo). The tiger is endangered across its range, which runs from the Russian Far East to the Indonesian island of Sumatra via North Korea, China, India, and Southeast Asia. The Siberian, or Amur, tiger (P. tigris altaica) is the largest, with a total length of up to 4 metres (13 feet) and a weight of up to 300 kilogrammes (660 pounds).The Indian tiger (P. tigris tigris), sometimes known as the Bengal tiger, is the most common, accounting for around half of the total tiger population. Males are larger than females, with a shoulder height of about 1 metre and a length of about 2.2 metres (excluding a tail of about 1 metre); weight is 160–230 kg (350–500 pounds); and southern tigers are smaller than northern tigers.Tigers in the Indo-Chinese (P. tigris corbetti) and Sumatran (P. tigris sumatrae) subspecies are vivid reddish tan with dark, almost black vertical stripes. The underbelly, inner sides of the limbs, cheeks, and a huge area over each eye are all white. Longer, softer, and whiter fur distinguishes the rare Siberian tiger. White tigers have been spotted on occasion, though not all of them are actual albinos, practically all of them in India (see also albinism).

Monkey

With the exclusion of lemurs, tarsiers, and lorises, a monkey is any of roughly 200 species of tailed primate. Monkeys are distinguished from apes by the presence of a tail (even if it is only a small nub), as well as their narrow-chested bodies and other skeleton traits. Although baboons and mandrills are significant exceptions, most monkeys have a small, generally flat face with little prominence of the muzzle. Tropical forests are home to the vast majority of animals, which move on all four limbs.During the day, all but the durukuli of tropical Central and South America are active, roaming in groups in search of plants, bird eggs, smaller animals, and insects to feed. Because monkeys can sit upright, their hands are free to do a variety of manipulating tasks. Monkeys, with the exception of a few Old World species, are primarily arboreal, leaping from limb to limb as they move through the trees. Both their hands and feet are utilized for grasping and contain five digits, with the thumb and big toe diverging from the others.The digits of most animals have flattened nails, while marmosets have claws on all of their digits save the big toe, which has a nail. Monkeys walk on the ground with their complete soles of their feet touching the ground but their palms up. They rarely walk on two legs (bipedally) and can only stand straight for brief periods of time, if at all.

                                           
           

Lion

 The lion (Panthera leo) is a huge, powerfully built cat of the Felidae family, second only to the tiger in size. The lion, the fabled "king of beasts," has long been one of the most well-known wild creatures. Lions are most active at night and can be found in a range of environments, but their preferred habitats include grassland, savanna, deep scrub, and open forest. They used to be widespread throughout most of Europe, Asia, and Africa, but currently they are mostly found south of the Sahara. In India's Gir National Park and Wildlife Sanctuary, an isolated group of about 650 Asiatic lions form a slightly smaller race that lives under extreme protection.The lion is a huge, muscular cat with short legs and a long body. The size and look of men and women differ significantly. The male's most distinguishing feature is his mane, which differs between individuals and communities. It can be completely absent, fringed around the face, or full and shaggy, covering the back of the head, neck, and shoulders and going across the throat and chest to join a fringe along the belly. The mane and fringe of certain lions are extremely dark, practically black, giving the animal a magnificent aspect.

                                                                     

Cow

A domestic bovine, regardless of sex or age, usually of the species Bos taurus, is known as a cow. Mature females of various large mammals, including cattle (bovines), moose, elephants, sea lions, and whales, are given the moniker. Domestic cows are one of the most common agricultural animals worldwide, and the English language has multiple words to characterise them at various stages of development. Calf refers to a young cow. A female calf is commonly referred to as a heifer calf, whereas a male calf is referred to as a bull calf. A heifer is a female that has never given birth. Heifers are normally young females; nevertheless, after giving birth to her first calf, a heifer becomes a cow. A bull is a term used to describe an adult male. Castration is used to minimise aggressive tendencies in male cattle and make them more tractable. A herd is a collection of cows, cattle, or kine (an old name for more than one cow). Because English lacks a gender-neutral singular word, "cow" is used to refer to both females and domestic cattle.

Dog

DOG, Canis lupus familiaris is a domestic mammal belonging to the Canidae family (order Carnivora). It is related to foxes and jackals and is a subspecies of the grey wolf (Canis lupus). The dog is one of the world's two most common and popular domestic animals (the cat is the other). It has been a hunting companion, guardian, object of derision or affection, and friend to humans for over 12,000 years.

From the grey wolf, the dog has evolved into over 400 different breeds. Humans have played a significant role in the development of dogs that meet specific societal needs. Dogs were bred to amplify tendencies that were visible from their first contact with people using the most basic kind of genetic engineering. The original dogs were hunters with excellent senses of sight and smell, despite the lack of facts concerning their evolution. As need or desire emerged, humans developed these impulses and formed new breeds.

Cats

CAT (Felis catus), commonly known as house cat or domestic cat, is the smallest domesticated member of the Felidae family of the order Carnivora. Domestic cats have supple low-slung bodies, finely shaped heads, long tails that aid in balance, and specialised teeth and claws that fit them admirably to a life of active hunting, just like all felids. Cats, like their wild relatives, are primarily carnivorous, highly agile and powerful, and well-coordinated in their movements.

It's worth noting that the dog's predecessors were social creatures who lived in packs and were subordinate to a leader, and the dog has easily shifted its allegiance from pack leader to human master. The cat, on the other hand, has not succumbed to servitude as easily. As a result, unlike most domesticated dogs, the house cat is able to revert to complete self-reliance more rapidly and successfully. See carnivore for further information on the relationship between cats and other carnivores.
