Without a insect, insects are the success successful group of organisms on the earth, both in terms of species diversity and number of individuals. But the radiation of insects is predominantly a terrestrial phenomenon.

Limitations of the basic insect design have restricted the radiation of insect species into the marine environment, although insects freshwater species do exist. Insect body design also constrains their essay size. Therefore, whilst insects have been successful in terms of diversity and overall numbers, the body plan that has made them so successful has prevented success into the sea or the evolution of larger individuals.
