FIGURE 4. Scolelepis (Scolelepis) squamata, morphometric characteristics. A, relationship between the body-size (referring to maximum anterior width in millimetres) and the palp length (in chaetiger number) (y = 7.6755 + 3.5999x; rs = 0.593; P <0.0001; n = 54). B, relationship between the total number of chaetigers and the first chaetiger on which neuropodial hooded hooks (triangles, y = 10.698 + 0.22969x; rs = 0.957; P <0.0001; n = 51) and the notopodial hooded hooks (circles, y = 9.2712 + 0.55917x; rs = 0.948; P <0.0001; n = 51) are present (black symbols—specimens from the Black Sea; white symbols—the Mediterranean Sea specimens from near type locality; red symbols—syntypes of Scolelepis mesnili; blue symbols—specimens from the Atlantic coast of Spain and France; green symbols—specimens from the North Sea and Kattegat). C, relationship between the body-size (referring to maximum anterior width in millimetres) and the number of teeth above main fang (y = 2.3168 + (−0.57224x); rs = −0.877; P <0.0001; n = 104).
