Morphometric study on tadpoles of <em>Bombina variegata</em> (Linnaeus, 1758) (Anura; Bombinatoridae)
The tadpoles of Yellow-bellied toad (Bombina variegata) can be easily recognized from other Italian anuran species, except those of B. pachypus (though the two congeneric species are allopatric). In this paper we report morphometric data on B. variegata tadpoles from a Lombard population living near...
