Ta Kou Marbled Gecko – Gekko takouensis – Ngo & Gamble, 2010

Science name: Gekko takouensis – Ngo & Gamble, 2010

Taxonomic:  Animalia>> Chordata>> Reptilia>> Squamata >> Gekkonidae >> takouensis

Species status: Endemic ; IUCN status: VU (Vunerable)

Description: Physical characteristics: Gekko takouensis is a medium-sized gecko with a snout-vent length (SVL) up to 107 mm. Its dorsum features 14–17 rows of smooth tubercles, with 83–93 scale rows at midbody. Males have 11–14 precloacal pores arranged in an angular series. The species has 18–20 subdigital lamellae on the fourth toe, and its dorsal pattern consists of 5–7 whitish vertebral blotches between the nape and sacrum, along with 6–8 pairs of short white bars or spots on the flanks between limb insertions.

Coloration and Appearance: The gecko’s dorsal side is marked by a series of light-colored blotches, while the sides display irregular spots or bars. The overall coloration helps it blend into its rocky surroundings.

Distribution and habitat: Elevation: Found at approximately 425 meters above sea level.
Area: Gekko takouensis is endemic to Ta Kou Mountain in Ham Thuan Nam District, Binh Thuan Province, Vietnam. It is restricted to this isolated granitic outcrop and has not been found elsewhere.
Habitat: This species inhabits granitic rocky areas within evergreen coastal forests. It is typically found on rocks and in narrow crevices in these areas, sharing its habitat with the Ta Kou bent-toed gecko (Cyrtodactylus takouensis).

Behaviour and ecology: Lifestyle: This species is nocturnal, emerging at night to forage on rocky surfaces near streams within its forest habitat. During the day, it shelters in rock crevices. It feeds primarily on insects and other small invertebrates found in the surrounding forest.

Reproduction: Gekko takouensis is oviparous, laying clutches of two eggs in crevices or rock cavities during the early rainy season each year.

Conservation and status: IUCN Red List Category and Criteria: Listed as Vulnerable (VU) due to its restricted distribution and potential threats from increasing tourism and habitat disturbance on Ta Kou Mountain.

Threats: The species is vulnerable to habitat destruction caused by tourism activities and potential environmental changes that may affect its limited range. Its habitat is also subject to human disturbance, which could lead to further declines in its population.

Conservation actions: Protecting Ta Kou Mountain’s habitat from further disturbance and ensuring responsible tourism management are critical to the conservation of Gekko takouensis. Monitoring population trends and habitat quality is recommended to safeguard this endemic species.
