id906, Natrix natrix, Croatia > Krk > Ponikve, 16 m a. s., Petr Vlček, 17.05.2007, 21.06.2007, There is an interesting and great variability in colouration (subspecies natrix, helvetica, persa) on Krk island. Additionaly they are succesfuly hybridising so we can find there lot of intermedeiate forms and aberations including melanistic individuals. By this fact the subspecies level is strongly in doubt.
