taken from mouth to the base of the hind leg, BD was taken where it was longest orthogonal to BL, TL was taken from base of the hind leg to tail tip, TD was measured where it is deepest and TMD was taken orthogonal to the “spine” right at its base
Morphological traits of Rana arvalis tadpoles measured at G32 and G38: body length (BL), body depth (BD), tail length (TL), maximum tail depth (TD) and tail muscle depth (TMD). BL was
