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.
yes
Yes, flies have exoskeletons. Flies are arthropods and all arthropods have an exoskeleton. More than 90% of creatures on earth are arthropods.
Arthropods
Arthropods were among the first animals to explore both terrestrial habitats (land) and aquatic habitats (oceans). Their success in adapting to various environments contributed to their widespread distribution and diversity on Earth.
A proposal exists that a couple organisms discovered just before the Cambrian period about 555 million years ago were the first arthropods found in the fossil record; by about 530 million years ago trilobites already showed significant diversity and world-wide distribution. There have been multiple mass extinctions inferred from evidence; but basically they've continuously occupied the Earth since.

I'm going to say....spiders...arachnids
When its probability distribution the standard normal distribution.
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
Arthropods ( EARTH SCIENCE )
Almost two-thirds of all named species of animals on Earth are arthropods. Arthropods are animals like crustaceans, spiders, and insects.
NO Mammals are not arthropods. Arthropods are insects.
