Staging tables based on the external morphological characteristics are important
for the needs of comparative embryological studies as they represent a baseline. Large bodied newts (Triturus spp.) have a transparent mucoid capsule that enables insight
into the external morphology of the embryo during development. Triturus newts are
characterized by the presence of chromosome 1 syndrome where about 50% of the
offspring stops developing and dies during the mid embryonic period on the tail bud
stage. In this study, we focused on the normal development of Balkan crested newt
(Triturus ivanbureschi). During the breeding season animals were kept in the yard of
the institute, in plastic tubs (from 200 to 400 liters), covered with a mosquito net that
allowed natural day-night regime. Plastic strips were provided as an imitation of
underwater vegetation, on which the females laid their eggs. Eggs were collected every
morning and moved to Petri dishes at the controlled experimental conditions. The
embryos were kept in the laboratory at a temperature of 20°C. Photographs and time lapse recordings of developing embryos were taken every day at the same time.
Compared to already published staging tables for newts and based on the appearance
of certain morphological structures, such as gills, extremities, balancers, etc., we
distinguished 37 different stages of normal embryonic development of T. ivanbureshi.
Still, differences in external morphology due to the balanced lethal chromosome 1
syndrome need further research
