First records of albino Aesculapian snakes (Zamenis longissimus) in Hungary

Body color abnormalities can significantly affect reptile fitness, as coloration plays a key role in ecological interactions such as mate selection, predator avoidance, and protection from environmental factors. Albinism—one of the most well-known color abnormalities—is caused by the absence of melanin. In wild snake populations, albinism cases are rare. This study reports the first documented cases of albino Aesculapian snakes ( Zamenis longissimus ) in Hungary.
