No they are different CC
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 .
Golly! There are tons of arthropods! Spiders are arachnids, which are arthropods. So are centipedes. Lobsters and crabs (and I think crayfish) are types of crustaceans, which are arthropods. And every insect you ever met, including ants, bees, wasps, and beetles, are arthropods.
Arthropods are invertebrates. An invertebrate is an animal without an internal skeleton and that's exactly what an arthropod is.
