How does a cat sharpen its claws?

Human fingernails and cat claws are made from keratin and keep growing their whole life.

Human fingernails do not retract (go in and out) – they do not go back into the skin to make them invisible. 

Most cats and wild cats have claws that are exposed or protracted when they use them and are hidden, sheathed, or retracted when they don’t need them.

Tongue of a Tiger

What does a tiger’s tongue look like?

Mammals have tongues. A tongue is a muscle. The left and right sides of the tongue are separated by a vertical section of fibrous tissue, called a lingual septum. A tongue has a tip and a blade (the part just behind the tip).

A tongue is used for chewing, tasting, licking, swallowing, washing, and making sounds. A tongue’s upper surface is covered with taste buds. The tongue has nerves and blood vessels, and is kept moist with saliva. It can be pink, reddish, or dark-coloured (like a giraffe’s tongue).

A human’s tongue is about 10 centimetres (4 inches) long. The Tiger (Panthera tigris) has a tongue that is about 18-23 centimetres (7-9 inches) long.

Tasmanian Tiger

The Tasmanian Tiger (Thylacinus cynocephalus) is an extinct Australian marsupial mammal. It was also called Tasmanian Wolf. It was not a tiger, nor a wolf, nor a dog (canid). It was a dog-like animal with stripes called a Thylacine. Extinct means that it is no longer living. The species has died out.

The Tasmanian Tiger was sandy-coloured with short soft hair and dark stripes on its back and its long tail. It had a pouch (similar to kangaroos and other marsupial mammals) to care for its young. Both male and female Tasmanian Tigers had a pouch, but only females had mammary glands in her pouch. It has a dog-like snout, round ears, and dark eyes. It had dog-like paws.

The Sumatran Tiger has rich, shiny orange-brown fur with broad, dark, irregular, vertical stripes. It has a white ruff around its neck and long, white whiskers. Its paws are broad and sharply clawed.

It is unlike most other tigers, because it likes to swim. It has webbing between its toes to enable it to swim. On land, it can run quite fast, and pounce.

CREATURE FEATURE: Bengal Tiger

The Bengal Tiger (Panthera tigris tigris) is a carnivorous mammal and the largest of the cat family.

The Bengal Tiger can grow to 1.5-1.8 metres (5-6 feet) tall with a tail of half a metre to one metre (2-3 feet) long.

Bengal Tigers live in the Bengal area of Bangladesh and eastern India.

They are an endangered species because the number of Bengal Tigers is decreasing. In 2014 the estimated population of Bengal tigers was about 3,000 with 2,226 in India, 440 in Bangladesh, 163-243 in Nepal, and 103 in Bhutan.
