How are insects and other arthropods alike?

Question

2-3 sentences

Answer 1

All of the members of the class Insecta belong to the phylum Arthropoda (commonly referred to as arthropods). Arthropods are nature's joint-footed animals that possess a hard, armor-like outer skeleton. The arthropods comprise about 95% of all known animal species. In fact, all but 5% of the arthropods are insects, so the insects outnumber all other animal species by 9 to 1! Non-insect arthropods include the classCrustacea (water-dwelling crabs, shrimp, crayfish and lobsters, and land-dwelling isopods or sowbugs), the class Diplopoda [dip-low-POH-dah] (many-legged, worm-like millipedes), the class Chilopoda [ki-low-POH- dah] (centipedes), the class Arachnida (mites, ticks, spiders, scorpions, and harvestmen), the class Xiphosura(horseshoe crabs), and the extinct class Trilobita (trilobites).

For example, the class Insecta is distinguished from other arthropod classes (and other animals) by the following characteristics: (1) exoskeleton divided into three parts, (2) three pairs of legs, (3) one pair of antennae, (4) compound eyes, and (5) many adults are winged
