Nyktos

Nyktos is a lesser-known genus of small, nocturnal geckos belonging to the family Gekkonidae, primarily found in the tropical regions of Southeast Asia. The name "Nyktos" derives from the Greek word *nyktos*, meaning "of the night," reflecting their crepuscular and nocturnal habits. These geckos are typically characterized by their slender bodies, large eyes with vertical pupils, and adhesive toe pads, which allow them to climb smooth surfaces and move silently.

Species within the genus are generally cryptic, blending into their surroundings with coloration ranging from dull browns and grays to more subdued greens. They inhabit a variety of environments, including forests, caves, and urban areas, often seeking refuge in tree bark, rocks, or human-made structures. Nyktos geckos are insectivorous, feeding primarily on small arthropods such as insects and spiders, which they capture using their keen senses of sight and hearing.

Little is known about their behavior and ecology due to their elusive nature and limited research. Some species may exhibit territorial behavior, particularly during mating seasons, while others are solitary. Reproduction typically involves internal fertilization, with females laying small clutches of eggs in concealed locations. Due to habitat loss and fragmentation, several Nyktos species face conservation concerns, though specific data on population trends remains scarce.

Nyktos geckos are not commonly kept in captivity, and their taxonomy remains understudied compared to other gecko genera. Some researchers suggest that further genetic and morphological studies may reveal additional species or clarify existing classifications. As with many nocturnal reptiles, their role in ecosystems is likely significant, though their contributions to biodiversity remain underappreciated.
