Tarantula Spider – Robert Lang
Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support. Like other Arachnida a tarantula’s body comprises two main parts, the prosoma (or cephalothorax) and the opisthosoma (or abdomen). The prosoma and opisthosoma are connected by the pedicel, or pregenital somite. This waist-like connecting piece is actually part of the prosoma and allows the opisthosoma to move in a wide range of motion relative to the prosoma.
Now I will guide you to fold a Tarantula spider with a sheet of paper.
Note: red line is valley crease, blue line is mountain crease.
1. Start with square origami paper, color size down.
2. Fold and unfold to make valley – crease, then flip the paper.
3. Fold and unfold, flip the paper.
4. Make three pinches as shown.
5. Fold and unfold.
6. Fold and unfold.
7. Fold for corners to four pinch marks.
8. From a truncated Preliminary Fold.
9. Fold the top point down.
10. Fold two corners to the front and two behind.
11. Turn over.
12. Fold and unfold to make crease.
13. Dent the top. Flatten fold.
14. Unsink the inside corner to outside. Repeat behind.
You will see:
15. Fold one rear layer to the right.
16. Fold down one layer.
17. Fold like a rabbit ear.
18. Unsink a single layer of paper.
19. Unsink another layer.
20. Unsink the remaining layer.
21. Fold one flap back to the right.
22. Fold and flap up.
23. Fold one layer to the right in front and one to the left behind.
24. Fold one flap down.
25. Fold one flap to the left so that the layer are symmetric about the center line.
26. Fold the flap back upward. Turn over.
27. Repeat steps 24 – 26 behind.
28. Reverse – fold 8 corners.
29. Fold and unfold to make crease.
30. Fold both corners to the crease you just made and unfold.
31. Make three more sets of vertical folds halfway between the existing creases. Turn over.
32. Repeat steps 29 – 31 behind.
33. Fold one large flap to the right in front and one to the left behind.
34. Repeat steps 29 – 31 in front and behind.
35. Fold and unfold the top.
36. Put the top inside (open – sink).
37. Collapse the corner (open – sink).
38. Open up a single layer to examine the top of the sink.
39. Close it back up.
40. Swing one flap over to the right.
41. Repeat steps 37 – 39on the left.
42. Collapse one corner (open sink).
43. Spread – sink three corners, spreading the layers symmetrically.
44. Turn the model over.
45. Collapse three corners on existing creases. (open sink)
46. Spread – sink three corners. Spreading the layers symmetrically.
47. Collapse both left corner and right corner (open sink).
48. Reverse – fold to make legs.
49. Valley – fold one edge of each flap so that the two edges at each corner are aligned then narrow all the flaps.
50. Fold down one flap. Rotate the legs to be perpendicular to the body.
51. Fold down thick flaps down.
52. Spread – sink 2 corners.
53. Sink the next two corners ( like a spread sink folder in half).
54. Mountain – fold the corner underneath.
55. Fold behind all but the two near flaps (though many layers).
56. Fold one layer to the right.
57. Fold one flap upward.
58. Fold the flap back to the left.
59. Repeat steps 58 – 60 on the right.
60. Open – sink the corners on the existing creases.
61. Open – sink the remaining pair of corners.
62. Fold the corner over and up and tuck in underneath the flap.
63. Mountain – fold. Repeat behind.
64. Pinch the flap and swing it to the left.
65. Pinch the base and mountain – fold the flap in half.
66. Repeat steps 66– 67 on the right.
67. Pleat the body.
68. Pinch the pedipalps. Shape the body.
69. Fold the chelicerae (mouthparts) downward. Round the abdomen.
70. Detail of pedipals. Crimp and shape.
71. Finish pedipalp.
72. Now we ‘ll fold the back legs.
73. Crimp a leg upward.
74. Shape all legs to a natural pose.
Your Tarantula is finished.
