Brown Tree Frog (Polypedates megacephalus), a common amphibian species in Hong Kong.

There are 24 species of amphibians in Hong Kong, with one species thought to be locally extinct.[1] There is one amphibian species, Liuixalus romeri, endemic to Hong Kong.[2] Amphibian fauna of Hong Kong fauna does not include any caecilians.

The most common amphibians one is likely to encounter are the Asian Common Toad, Brown Tree Frog and Asiatic Painted Frog.

List of amphibians

Order Caudata

Family Salamandridae (Salamanders)

Subfamily Pleurodelinae (Newts)
Hong Kong Newt (Paramesotriton hongkongensis), the only tailed amphibian species in Hong Kong

Order Anura (Frogs and Toads)

Family Bufonidae (Toads)

Adult Brown Wood Frog (Hylarana guentheri) in Sai Kung East Country Park, Hong Kong

Family Rhacophoridae (Gliding Frogs)

Romer's Tree Frog (Chirixalus romeri), endemic species in Hong Kong
  • Romer's Tree Frog (Liuixalus romeri) - Endemic to Hong Kong.
    • This species was considered as Philautus romeri. A study is done to review 177 nominal species in the genus Philautus replaced Romer's Tree Frog from genus Philautus to Chirixalus since species in genus Philautus do not have a free-living tadpoles stage. (Banks et al., 2008; Bossuyt & Dubois, 2001)
  • Brown Tree Frog (Polypedates megacephalus)

Family Microhylidae (Narrow-mouthed Frogs)

Threats of Hong Kong amphibians

Despite the semi-terrestrial mode of life, amphibians are closely associated with water because of breeding. Rapid development in Hong Kong has resulted in the loss of many low-lying wetlands which were once important amphibian habitats; this has led to a severe decline in the populations of certain lowland species, such as the Rough-skinned Floating Frog (Occidozyga lima), which inhabited the once-abundant, but no longer existing paddy fields in Tung Chung and is now thought to be locally extinct.

Pollution of water bodies and acid rain also affect an individual's survival. In general, the diversity of amphibians decreases as the pollution level in a water body increases. Only some hardier pollution-tolerant species, such as Günther's Frog and Asian Common Toad, can thrive in polluted habitats.

Some exotic/market amphibian species are occasionally seen in the countryside, such as the American Bullfrog. Some are deliberately released during Buddhist ceremonies. These released animals can adversely affect the local ecosystem and native fauna, as they may prey on, compete with, or spread disease to the native amphibian fauna.[6]
