What can you say about the distribution of arthropods on earth?

Arthropods are the most diverse and abundant group of animals on Earth, with over a million described species and estimates suggesting that there may be millions more yet to be discovered. They inhabit a wide range of environments, from deep oceans to high mountains, and can be found in almost every ecological niche. This distribution is facilitated by their adaptability, varied life cycles, and ability to exploit different food sources, making them integral to many ecosystems as pollinators, decomposers, and prey for other animals.
