Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs.
They come in all shapes and sizes. Some walk, some slither, some fly and some swim. Humans are blessed to share the planet with just over 2.1 million recognized species of animals. And scientists ...
In the English language, many animals have different names depending on whether they are male, female, young, domesticated, or in groups.

Unusual names have caused issues for scientists explaining genetic diseases to lay-people, such as when an individual is affected by a gene with an offensive or insensitive name. [13] This has particularly been noted in patients with a defect in the sonic hedgehog gene pathway and the disease formerly named CATCH22 for "cardiac anomaly, T-cell ...
Well-known examples of rare species - because these are large terrestrial animals - include the Himalayan brown bear, Fennec fox, Wild Asiatic buffalo, or the Hornbill. They are not endangered yet, but classified as "at risk", [ 5 ] [ 6 ] although the frontier between these categories is increasingly difficult to draw given the general paucity ...
Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found. Over 500 million years ago ...
