  • Phylum Arthropoda

  • 2x

    Area = 1 Strength = 1 Weight = 1 Strength/wt = 1

    Area = 4 Strength = 4 Weight = 8 Strength/wt = 1/2

  • Exoskeleton like tube Endoskeleton like rod

    Per unit weight, tube is stonger than rod

  • Generalized arthropod - Segments - Exoskeleton - Ventral nervous system with anterior,

    dorsal brain

  • tagmatization

  • Tracheal system - Spiracles - Trachea - tracheoles
