“Indo-Pacific gecko”的意思、由来-开放百科全书

The Indo-Pacific gecko (Hemidactylus garnotii) also known as Garnot's house gecko, the fox gecko, or the Assam greyish brown gecko, is a species of gecko found in India, the Philippines, Southeast Asia, Australia, and throughout Polynesia. Adults are about {{convert|4|to|5|in|cm|abbr=on}} in total length (including tail). They are seen as dark gray or brown with light markings in daylight and a pale, translucent colour at night. The belly is orange or yellow. The head has a long, narrow snout, hence the name fox gecko. The flattened tail has a row of spiny scales on the lateral edges. The species is parthenogenic – all individuals are female and lay eggs that hatch without requiring male fertilisation.^[2]

In Hawaii, the species is thought to be a long-term resident. Formerly considered a house gecko, it has been displaced to natural habitats by the more recently arrived common house gecko.^[2] In Florida and Georgia it has become established as an invasive species of concern.^[3]^[4]

Etymology

The specific name, garnotii, is in honor of French naturalist Prosper Garnot.^[5]

Tail depressed, flat beneath, with sharp denticulated lateral edge; the scales on the upper surface very small, equal; those on the lower surface larger, imbricate, with a median series of large, transversely dilated plates.^[7]
