Arthropods By @ndre’ Morgan
Arachnids • Their body consists of two main parts: a fused head and thorax, and an abdomen. • There are six pairs of appendages on the body: the first pair are clawlike fangs near the mouth used for grasping and cutting; the second pair serve as general-purpose mouth parts that may be modified for special functions; and the last four pairs of appendages are the walking legs. • They have eight legs. • Examples: Spiders and Scorpions
Crustacea • The head has two compound eyes, two pairs of antennae, and three pairs of mouthparts. • A pair of green glands excrete wastes near the base of antennae. • A hard exoskeleton made of calcium - no internal skeleton. • Examples: Crab and Lobster
Diplopoda • 2 pairs of legs per body segment, although some juveniles may posses only 1 pair per segment. • Simple eyes if present, although many have no eyes. • 1 pair of antennae. • Examples: Millipede
Insecta • Two pairs of wings. • Three pairs of jointed legs. • Tri-segmented bodies: head, thorax, and abdomen. • Examples: Butterfly and Beetles
