(一)蛛形纲 Arachnida Scorpion蝎, spider蜘蛛,and mitel 螨 bodies -- cephalothorax and abdomen head without antennae a usually bearing eight legs

（一）蛛形纲Arachnida ◼ Scorpion蝎, spider蜘蛛, and mite螨 ◼ bodies -- cephalothorax and abdomen. ◼ head without antennae. ◼ usually bearing eight legs

(二)甲壳纲 Crustacea a body- head, thorax, abdomen Head and thorax often closely jOined as cephalothorax ■2 pairs of antennae Usually at least 5 pairs of legs Abdomen having short appendages ■ Mostly hydrophilous shrimp 虾、 lobster龙虾、crab蟹

（二） 甲壳纲Crustacea ◼ Body -- head, thorax, abdomen ◼ Head and thorax often closely joined as cephalothorax; ◼ 2 pairs of antennae ◼ Usually at least 5 pairs of legs ◼ Abdomen having short appendages ◼ Mostly hydrophilous ◼ shrimp虾、lobster龙虾、crab蟹

(三)唇足纲 Chilopoda ■ centipedes蜈蚣 ■ a pair of antennae Bodies very long, each egmont with a pair of egs. The first pair appendages modified into poison claws

（三）唇足纲Chilopoda ◼ centipedes蜈蚣 ◼ a pair of antennae. ◼ Bodies very long, each segment with a pair of legs. ◼ The first pair appendages modified into poison claws

(四)重足纲 Diplopoda millipedes马陆. ■ body segments fused into pairs Each apparent segment has two pairs of appendages

（四）重足纲 Diplopoda ◼ millipedes马陆. ◼ body segments fused into pairs ◼ Each apparent segment has two pairs of appendages

(五)昆虫纲 Insecta 1. Bodies into cephalic thoracic and abdominal regions 2. Head carries Thorax Compound Eye mouth Ocellus Abdomen art. one pair Antenna of antennae Mandible 3. Usually with 3 pair of labu Trochanter Maxilla and Labium and maxillary palp legs and a pair of labial palp Tibia Wings in the adult
