Modern forms

Although the trilobites were present in the oceans for 350 million years, they died out at the end of the Permian. There is nothing alive today that is exactly the same as trilobites although insects, crustaceans (crabs, lobsters, etc), and arachnids (spiders and scorpions) are relatives.  The closest relative is the horse shoe crab Limulus.
