Animals are incredibly diverse, with millions of species found across the world’s ecosystems — from the deepest oceans to the highest mountains. Among them, insects are the most numerous, especially beetles, which make up a large portion of known animal species. Mammals, birds, reptiles, amphibians, and fish form the other major groups. Commonly found species include ants, pigeons, rats, cows, dogs, and cats — many of which have adapted to live alongside humans. Marine life like jellyfish, tuna, and plankton are also found in large numbers, while forests are rich with species like deer, monkeys, and snakes.
On the other hand, many species are facing extinction due to habitat destruction, climate change, pollution, and illegal hunting. Some of the most critically endangered animals include the Javan rhino, Amur leopard, Vaquita (a rare marine porpoise), and Northern Bald Ibis. Amphibians like certain frog species and reptiles like turtles are among the most threatened. According to the IUCN Red List, over 40,000 species are threatened with extinction, making conservation efforts crucial to preserving the planet’s biodiversity.
