Lepidophyma – Tropical night lizards
Unlike many other lizards, they don't bask in the sun
These lizards are known for being nocturnal, reclusive, and unusually long-lived for their size. Despite their tiny size and quiet lifestyles, Lepidophyma lizards are remarkably tough survivors, thriving in places where few other reptiles do — often hidden under rocks, logs, or deep in crevices where moisture lingers.
Tropical night lizards are typically small, usually under 12 cm (5 inches) in length, with short limbs, broad heads, and granular, pebbly scales that give them a rough texture. Their colors range from dark gray to brown or olive, often with subtle patterns that help them blend into rocky or mossy surroundings. These lizards have large eyes with vertical slit pupils, perfect for night vision, and eyelids that are fused, giving them a glassy-eyed look. They’re mostly active during twilight or nighttime hours when temperatures are cooler and humidity is higher.
One of the most interesting things about Lepidophyma species is that many of them are viviparous — meaning they give birth to live young, rather than laying eggs. This trait helps them thrive in cool, shaded environments where egg-laying reptiles might struggle to incubate their clutches. These lizards are insectivores, feeding on tiny invertebrates like ants, termites, spiders, and beetles, and they rely on stealth and camouflage to avoid predators. They move slowly and cautiously, making them hard to spot even when active.
Some tropical night lizards are incredibly long-lived for their size — in captivity, certain species have lived for over 20 years, which is rare for such small reptiles. Another interesting note: because many species have such small and isolated ranges — sometimes limited to just a single mountain or canyon — they are important indicators of ecosystem health and stability.
