Species description

Geographical Origin and Habitat: Chelydra serpentina (commonly known as Common snapping turtle) is a semi-aquatic turtle native to Eastern North America, from southern Canada to Florida, where it inhabits large shallow bodies of freshwater, muddy ponds, marshes, and slow rivers.

Taxonomy and Genetics: Belongs to the family Chelydridae, genus Chelydra. It displays unique morphological characteristics that set it apart from other freshwater turtles.

Behavior and Habits: Diurnal and semi-aquatic. It spends much of its time in the water but regularly climbs onto dry platforms to bask.

Morphology: Adults grow to an average size of 38.0 cm. Males are identified by a longer tail with the cloaca near the tip.

Care, breeding and tankmates

Terrarium Setup: Paludarium setup of at least 400 liters, featuring a deep swimming section and a dry land area with easy access.

Lighting and Heating: Keep water temperature at 10.0-28.0°C. Provide a land basking spot at 30.0°C. UVB light is essential.

Humidity and Hydration: Maintain air humidity around 60-80%. Clean water is paramount; use a high-powered filter for waste extraction.

Feeding and Supplementation: Highly carnivorous diet consisting of live insects, worms, and small fish. Dust food with calcium twice a week.

Compatibility: Extremely territorial. Must be kept alone to prevent severe territorial aggression and physical injuries.

Health and Common Diseases: Vulnerable to shell rot due to dirty water and Metabolic Bone Disease (MBD) if UVB radiation is missing.
