Geckos

Family Gekkonidae1


Geckos are well known for their ability to hang upside down on ceilings. The "House Lizards" that one typically encounters at home are really geckos. There are 19 species that can be found in Singapore. At least 4 of them can be found in houses. The rest are forest geckos.

  1. Fox-faced Gecko (Aeluroscalabotes felinus)
  2. Peninsular Rock Gecko (Cnemaspis peninsularis)
  3. Frilly Gecko (Cosymbotes craspedotus)
  4. Flat-tailed Gecko (Cosymbotes platyurus)
  5. Peter's Bent-toed Gecko (Cyrtodactylus consobrinus)
  6. Singapore Bent-toed Gecko (Cyrtodactylus majulah)
  7. Peninsular Bent-toed Gecko (Cyrtodactylus semenanjungensis)
  8. Four-clawed Gecko (Gehyra mutilata)
  9. Tokay Gecko (Gekko gecko)
  10. Spotted House Gecko (Gekko monarchus)
  11. Large Forest Gecko (Gekko smithii)
  12. Brooke's House Gecko (Hemidactylus brookii)
  13. Common House Gecko (Hemidactylus frenatus)
  14. Indo-Pacific Gecko (Hemidactylus garnotii)
  15. Dwarf Gecko (Hemiphyllodactylus typus)
  16. Mourning Gecko (Lepidodactylus lugubris)
  17. Brown's Flap-legged Gecko (Luperosaurus browni)
  18. Horsfield's Flying Gecko (Ptychozoon horsfieldii)

Sometimes foreign geckos followed shipments into Singapore. Here are two that might have done so.

Used to be grouped with Kendall's Rock Gecko, the Peninsular Rock Gecko (Cnemaspis peninsularis) is now treated as a separate species2.

The Flat-tailed Gecko (Cosymbotes platyurus) is another urban gecko. It can be told apart by the flat edges of the tail.

The Singapore Bent-toed Gecko (Cyrtodactylus majulah) has previously been mistaken as Marbled Bent-toed Gecko (Cyrtodactylus quadrivirgatus)3. It has black spots on its back. In some, the black spots merged to form alternative black and pale bands on the back.

The Four-clawed Gecko (Gehyra mutilata) is another urban gecko. It does not have the spiny tail of the above species and only four of the five toes on each hind foot have claws.
