The name for phylum Arthropoda is derived from "jointed legs" or jointed feet, and arthropods live up to that name. Because of the rigidity of the exoskeleton, joints are apparent in any of their mobile appendages; not just legs but some specialized appendages like swimmerets for aquatic arthropods, antennae, wings, all evidence some kind of jointing. Legs themselves may have specialized adaptations; some insects hear or taste with special organs on the legs or feet. Some crustaceans have legs bearing claws (chela) called chelipeds.
This is effectively the definition of insects.
Insects (everything with six legs), arachnids (eight legs), crustaceans (ten legs), and centi/millipedes (many legs). ^^
they are all jointed
They are jointed.
no
Anthrops have an exoskeleton which becomes harder as it matures it moves like any other insect it moves its legs
Anthropods (humans) do not have wings; not to be confused with phylum Arthropoda (arthropods). Many arthropods have wings (insects are arthropods, including flying insects), but, of course, not all of them.
lizards and other anthropods but not all
The groups, or classes, within the phylum of the Arthropoda are Hexapoda (insects and a few others), Chelicerata (scorpions, spiders and some others), Crustacea (crabs, lobsters, barnacles, krill, loads of other things) and Myriapoda (centipedes and millipedes). Basically six legs, eight legs, ten legs, lots of legs.
Yes
with their mouth i think
It is the essential principle of Animalism
