Anomalous pigmentation in a young Marbled Newt, <i>Triturus marmoratus</i> (Latreille 1800), from northwestern Spain

marmoratus) are medium-sized newts (115-149 mm total length in males, 130-162 mm in females) endemic to the northern Iberian Peninsula and southern France (Herrero et al. 2003;Garca-Pars et al. 2004).The predominant ground color is green or greenishyellow with numerous prominent black spots that collectively form a reticular pattern (Montori 2014).During the aquatic phase, these newts primarily occupy still waters (i.e., natural and artificial ponds, water troughs, lagoons, pools, reservoirs, water tanks, backwaters, bends, or abandoned arms, pools, and areas of aggregate extraction or abandoned quarries that accumulate water), particularly those that maintain a considerable volume of water and are characterized by a substantial presence of aquatic vegetation, but avoiding areas with even moderate currents (Montori 2014).
