42. 41 Eurypterida – Giant sea scorpions Xiphosura – Horseshoe crabs Pycnogondia – Sea spiders

43. 42 What does the word “Hexapoda” actually mean and what type of organisms are considered hexapods?

44. 37 Hexapoda means “six legs” and the hexapods are commonly known as insects

45. 44 What are the three main body segments found in hexapods?

46. 45 Head, thorax, & abdomen

47. 46 What four major mouthpart adaptations may be seen in hexapods?

48. 47 Chewing, sponging, siphoning, and piercing

49. 48 What are spiracles and how does bug spray exploit spiracles to kill insects?

50. 49 Spiracles are tiny holes in an insect’s exoskeleton through which oxygen enters the body. Insect spray clogs up these holes causing the insect to suffocate.

51. 50 Describe how a honeybee’s waggle dance can show other bees where food is located?

52. 51 The bee conveys direction by the angle of the dance in relation to the sun. The bee conveys distance by the number of waggles in each dance cycle.

53. 52 From what arthropod Subphylum did the hexapods evolve and how did this evolution proceed?

54. 53 The hexapods evolved from the myriapods. The elongated body of myriapod ancestors broke into three regions. The legs on the head region evolved into complex mouthparts, the three pairs of legs on the thorax grew large enough to support the whole body, and the legs on the abdomen reabsorbed into the organism as it evolved.
