Reptile Glossary

A specialized container for keeping reptiles. Available in glass, acrylic, and wood, the enclosure must provide adequate size and ventilation for the species. Front-opening models with escape-proof locks are the most practical.

A spotlight-type lamp that provides light and heat for reptiles to raise their body temperature. It creates a focused hot spot in one area of the enclosure, enabling the animal to thermoregulate.

A reptile-specific lamp that emits ultraviolet B radiation. It is essential for synthesizing vitamin D3 in the body, which promotes calcium absorption. A deficiency can lead to metabolic bone disease (MBD).

A localized warm area inside the enclosure created by a basking light. Reptiles bask here to raise their body temperature and aid digestion. It is typically set to around 30–40°C depending on the species.

A natural physiological process in which reptiles shed old skin as they grow. Snakes shed in one piece, while lizards and geckos shed in patches. Adequate humidity is crucial to prevent incomplete shedding (dysecdysis).

The practice of lowering enclosure temperatures for a set period to simulate winter and stimulate breeding. The appropriate temperature and duration vary by species, and it should only be performed on healthy animals. It is a fundamental technique for breeders.

Short for Captive Bred — an animal bred in captivity by a breeder. CB animals adapt more easily to captive conditions and carry a lower risk of parasites, making them especially suitable for beginners.

Short for Wild Caught — an animal captured from its natural habitat. Compared to CB animals, WC specimens carry higher risks of parasites and disease and may be harder to tame, but they often display unique wild coloration and morphology.

Food offered alive, such as crickets, Dubia roaches, and mealworms. Live feeders stimulate a reptile's feeding response and are highly nutritious. Dusting them with calcium powder before feeding is standard practice.

Frozen mice fed to carnivorous reptiles such as snakes and monitors. Sizes range from pinky to adult. They should be thawed in lukewarm water and warmed to roughly body temperature before feeding.

A thin electric heater placed under or beside the enclosure. It warms only a section of the tank, creating a temperature gradient. Commonly used for terrestrial reptiles and nighttime heating.

A temperature controller that automatically regulates heater and light output to maintain a set temperature. It is an indispensable piece of equipment for keeping enclosure temperatures stable and also serves as a safety device to prevent overheating.
