Lioness and her cubs

A female lion is called a lioness. The lioness has 1-4 young, called cubs. Cubs are born with their eyes closed. They open their eys after 3-10 days. 

The lioness is very protective of her cubs, particularly for the first 8 months (240 days), before they join the rest of the pride. Other lionesses and their cubs will live together and look after all of the cubs. This is called allomothering.

Sika Deer’s eyes

A Sika Deer (Cervus nippon) has excellent vision. It can detect movement from a long distance away. 

A Sika Deer does not have a round pupil, like the pupil of a human eye. It does not have a slitted pupil, like the pupil of a domestic cat. 

A Sika Deer has an elongated pupil. It looks like a raisin, or a flattened grape. 

A full arc of vision is 360 degrees. A human has an arc of vision of 120 degrees (a human cannot see objects behind it). A Sika Deer has an arc of vision of 310 degrees, which means that it can see almost all around it.

Zygodactylous Feet – Chameleon Feet

The Chameleon has zygodactylous feet. Zygo means paired, joined, or fused, and dactyl means digit (finger or toe). Scientists would like a more appropriate word, because the chameleon does not have true zygodactylous feet, like the parrot.

It has five toes on each foot. The toes are grouped into two fascicles (a bundle of structures).

Two or three toes in each fascicle are fused together, which makes its feet look like tongs (the tongs people use in the kitchen to pick up food).

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.
