Insecta you nucking retards!
Insecta
By far, the most diverse group of arthropods is the insects superclass. More than 1,000,000 species are known to date! Runners up are the Chelicerata (Spiders, scorpions, horseshoe crabs, etc) with 77,000 species, and then the Crustacea (crabs, lobsters, etc) with 50,000 species. In last place are the myriapods (centipedes, millipedes, etc) with 13,000 species.
Do you mean arthropods? If so, your question needs to be more specific. According to National Geographic, arthropods are the single most diverse group of animals. Among that group, you can find a variety from butterflies to tarantulas to horseshoe crabs to ticks to lobsters. So as far as what arthropods kill, you would have to narrow your focus.
Endo = inside. Endoskeletons are skeletons like ours, bones on the inside. Arthropods have EXOskeletons, armour on the outside.All arthropods have segmented bodies with tough exoskeletons made from chitin.
By count the most arthropod species fall under the Insecta class, with a million species described and millions estimated yet to be described, evidencing an immense diversity. By count, insects are over half of all living animals and by some estimates may constitute up to ninety percent of all living animals on Earth.

Insecta...Cant Explain. Sorry. =) Try To Google It...
The Tiger Snake
The Arthropods are the largest and most diverse.
The phylum with the second most diverse range of species is Arthropoda, which includes insects, arachnids, crustaceans, and other groups. Arthropods have a wide variety of adaptations and occupy diverse habitats, making them one of the most successful and numerous groups of animals on Earth.
InsectsNote: This answer is acceptable if by group you were asking for Class. But the most diverse "group" would be invertebrates, since they are ~95% of all animals. If you were asking for Phylum, it would be Arthropoda.Canis lupus would be an incredibly diverse species.
Arthropods have the largest and most diverse group of species known, so their appearance varies vastly depending on habitat and specific adaptations, but some characteristics that are apparent on all are the jointed appendages, body segmentation, and an exoskeleton made of chitin.

All arthropods apart from most insects have wings.
There are two: the tropical rainforests and the temperate rainforests. They have five tropic levels.
Arthropods reproduce sexually . Fertilization is mostly internal but in some species it is indirect . In most arthropods fertilization is direct . Most arthropods are oviparous i.e. they lay eggs . Metamorphosis takes place .
Most aquatic arthropods have external gills
The classes of phylum Arthropoda include Insecta (insects), Arachnida (spiders, scorpions, ticks, and mites), Crustacea (crabs, lobsters, shrimp, and barnacles), and Myriapoda (millipedes and centipedes). These classes are characterized by their jointed limbs, segmented bodies, and exoskeletons.
