Estimation of Surface Area and Volume of a Nematode from Morphometric Data

Figure 1

The development of the unweighted Bézier representation of Aplectus antarcticus. The morphometric data of Cobb [21] (●) and two supplementary coordinates (○, (0, 0) and (1, 0)) are shown. The 7-coordinate version of the unweighted Bézier representation (27)–(30) is the solid line in (a), which is reflected along the horizontal axis to give the dashed line in (a). The extended 13-coordinate Bézier representation in (b) is explained in the text, as is the edited extended representation (c) that is derived from it. The dotted line in (c) represents the region from (0.001, −0.004) to (1, 0) that is reflected about the horizontal axis to form the upper boundary. Note that the vertical and horizontal dimensions differ in scale by a factor of 10 relative to the overall length of the nematode ( = 0.6 mm).
