Arthropods

Insects are the only winged arthropods.

Insects are arthropods.

Arthropods have more feet.

Trilobites fossils are arthropods, or joint-footed animals, with a segmented body of hinged plates and shields. They could curl up into a ball for protection, sometimes fossilizing as a "rolled" trilobite.

Like arthropods today, trilobites molted as they grew, shedding their old exoskeleton. These molts could fossilize, so one animal could leave several different sized fossils behind.

Lobsters and insects are arthropods.

Lobsters and insects belong to the same phylum known as arthropods.

Arthropods must shed the exoskeleton in order to grow or assume a new form.

Centipedes are predatory arthropods known for their venomous bites.

Arthropods have external skeletons.
