Odorrana supranarina is a species of

Rana narina complex.[2] Common name greater tip-nosed frog has been coined for it.[1][3]

Description

Adult males measure 59–77 mm (2.3–3.0 in) and adult females 81–103 mm (3.2–4.1 in) in snout–vent length. The body is stout with triangular head; the snout is pointed. The

dorsum is smooth. Dorsal ground colour varies from light brown to greenish brown; there are no distinct markings. There are dark markings below the canthus, around the tympanum, and along the dorsolateral fold. The limbs have dark crossbars. Males have paired subgular vocal sacs.[2]

Tadpoles are rather slender and have long, muscular tail. A newly metamorphosed individual measures about 13 mm (0.5 in) in snout–vent length.[2]

On both Ishigaki and Iriomote, Odorrana supranarina is

sympatric with Odorrana utsunomiyaorum, a "dwarf" species in relative terms. As O. supranarina is a "giant" species, it appears that the body sizes of these two species have diverged, perhaps in response to competition.[2]

Habitat and conservation

Odorrana supranarina inhabits broad-leaved evergreen forests along mountain streams. However, it can also be found in coastal areas,[1][2] in riverside forests just outside the mangrove.[2] Breeding takes place in October–March in shallow streams and in pools. The eggs are attached to stones or dead leaves under the water.[2]

The species has a small and fragmented range.

Habitat loss and degradation caused by logging and human settlement are threats to it, particularly on Ishigaki. Iriomote is a national park, but improved protection of its forest habitats is still needed.[1]
