Eight Species of Anuran Amphibians (Amphibia, Anura) Found in Ukraine: Comparative Morphology and Classification of Larval Development Stages

Abstract

Morphological characteristics typical for larval development stages of eight species of anuran amphibians found in Ukraine have been compared. Outer morphological features common for these species have been identified. Morphological features are suggested for determining the stages of larval development of various anuran amphibian’s species, as well as the numbering of the stages aſter the larvae exit from the spawn membranes.
