Changes in body length proportions in Mertensiella caucasica (open square) and Salamandra salamandra (solid square) during ontogenesis. 1- larvae with total length less than 35 mm; 2- larvae with total length greater than 35 mm; 3- yearlings; 4- juveniles; 5- adults, solid line- L/Lccj; broken line- 1/LC. The coefficients of static allometrical equations for recently metamorphosed animals are: Lcd= Lc= Hence, the most rapid comparative increasing of tail length is during late larval development. The comparative decreasing of head is the most rapid in the I and II size groups, but later this process isn't so clear. Nevertheless, it takes part in metamorphosis. Plenty of eco-morphological features separate M. caucasica from the other representatives of European salamander tribe, depended on subtilization (Ozeti, 1967). The latter is a base determined ecological similarity between M. caucasica and C. lusitanica (Borja-Sanchiz and Mlinarsky, 1979). Perhaps this is a reason of similar breeding ways of these species differing from other European salamanders. The changes of general proportion of M. caucasica and S. salamandra, which are shown in Fig. 14, allow a comparison of these species. The general trends of body proportion changes are common in the two species (as in most Tetrapoda): the comparative length of head (L/Lc) decreases and that of tail (L/Lcd) increases. But in these tendencies, both are quite rapid in M. caucasica. In S. salamandra the changes are gradual and moreover, tail length growth is poorly distinguished (Fig. 14).
