Figures
- Fig. 1.
Rendering of movable finger of Rhagodes. Measurements were taken on the movable finger to calculate mechanical advantage. T, tip; MT, main tooth; LI, muscle insertion for levator muscle; J, joint.
- Fig. 2.
Dorsal view of Galeodes (left) and Rhagodes (right). Clearly, the burrowing Rhagodes has relatively larger chelicerae and shorter legs than the cursorial Galeodes. These images are not to scale.
- Fig. 3.
Renderings of Rhagodes (A) and Galeodes (B) showing the position of the depressor digitus mobilus (dark blue) relative to the movable finger (green), tendon (transparent red) and levator muscle (transparent blue). Scale bars are 5 mm.
- Fig. 4.
Renderings of Galeodes chelicerae. (A) Lateral view of left chelicera. (B) Movable finger (green), tendon (red) and levator muscle (transparent blue). (C) Dorsal overview image of chelicerae and propeltidium (yellow). (D) Caudal view of levator muscle and tendon, showing the five lobes of the tendon, as well as the large longitudinal spaces (dorsal) and the space occupied by the depressor muscle (ventral). All scale bars are 5 mm.
- Fig. 5.
Renderings of Rhagodes chelicerae. (A) Lateral view of left chelicera. (B) Movable finger (green), tendon (red) and levator muscle (transparent blue). (C) Dorsal overview image of chelicerae and propeltidium (yellow). (D) Caudal view of levator muscle and tendon, showing the five lobes of the tendon, as well as the large longitudinal spaces (dorsal) and the space occupied by the depressor muscle (ventral). All scale bars are 5 mm.
- Fig. 6.
Maximum bite force plotted against chelicera length (A), width (B), height (C) and the product of length × width × height (LWH, D) on log–log axes. Although overlap exists between the two species in chela measurements, Rhagodes (circles) has higher bite forces than Galeodes (squares) for similar chela dimensions.
