Redigobius leveri (Fowler)

Lever’s Goby (Redigobius leveri)

Lever’s Goby is endemic to the Fiji Islands.

This tiny freshwater goby, which may reach a body length of only about 4 cm, lives in several creeks and rivers in the lowlands of Fiji’s larger islands, but seems, however, not to occur on the island of Vanua Levu.

The fish stays mainly near the bottom of the water and feeds on smaller invertebrates.

Hippichthys cyanospilos (Bleeker)

Blue-spotted Pipefish (Hippichthys cyanospilos)

The Blue-spotted Pipefish is indigenous to the tropical Indo-Pacific, and occurs in the east up to the Fiji Islands, where adult individuals can be found in coastal rivers, and estuaries as well as in mangroves.

This about 16 cm long species is quite variable colored, and can be pale yellow to nearly black in color.

As in all relatives of the seahorses, also in this species the eggs are carried and brood by the males in a brood pouch.

Awaous ocellaris Broussonet

Eyespot Goby (Awaous ocellaris)

The Eyespot Goby is an about 13 cm long freshwater goby that is indigenous to many mangrove areas, estuaries, and rivers from India to Polynesia.

The fish feed on green algae, small crabs, freshwater shrimps, and other invertebrates.

Like all Polynesian freshwater gobies, also the Eyspot Goby has an amphidromous life cycle, which means, that the spawning takes place in the freshwater, but the embryos are washed out into the ocean, where they remain for a planktonic phase before they return into freshwater to grow and to start the life cycle again.

The Samoan name of the species is mano’o ia pala.

Smilosicyopus bitaeniatus (Maugé, Marquet & Laboute)

Two-banded Goby (Smilosicyopus bitaeniatus)

The Two-banded Goby was described in the year 1992 from specimens that had been collected in a river named Vaioa on the island of Hiva Oa.

This only about 3,5 cm long species is endemic to the Marquesas, where it can be found in fast flowing, clear streams.

Lentipes kaaea Watson, Keith & Marquet

Red-nosed Goby (Lentipes kaaea)

The Red-nosed Goby, which is closely related to the Red-banded Goby (Lentipes rubrofasciatus Maugé, Marquet & Laboute), was described in the year 2002.

The Red-nosed Goby occurs in swift, clear streams with rocky bottom.

The tiny males are only about 3 cm long, their front body is glimmering greenish to dark blue, the forehead is bright red to purplish red in color, the second dorsal fin and the body area below are likewise bright red in color. The females, which are about 4,5 cm long, are light brown in color and show some darker brown marbling.

The species was originally known only from New Caledonia and from Vanuatu, but was later found to occur as well on the Fiji Islands and on Wallis and Futuna. [1][2]

Stenogobius genivittatus (Valenciennes)

Chinstripe Goby (Stenogobius genivittatus)

The Chinstripe Goby is an endemic species of the Society Islands, where it occurs on the islands of Mo’orea and Tahiti.

The species lives in freshwater in streams and estuaries, and wanders well upstream, however, it is not able to overcome natural barriers like waterfalls and, therefore, is restricted to the lower reaches of the streams near the sea.

The Chinstripe Goby feeds on insects, crustaceans and smaller fishes. [1]

Giuris margaritacea (Valenciennes)

Snakehead Gudgeon (Giuris margaritacea)

The Snakehead Gudgeon is the only species of its genus, it is widely distributed over large parts of Asia as far away as Australia and beyond, and inhabits flowing and stagnant freshwater bodies with dense plant growth.

The fish reaches a length of about 23 cm.

The Snakehead Gudgeon feeds on various smaller animals but also on algae.

The species, like almost all of the Polynesian goby- and sleeper goby species, has a pelagic marine larval stage, that means the larvae live among the marine plankton for several months, and then return back into their birth rivers.

~~~

The Hoofprint Goby (Lairdina hopletupus Fowler) from the Sigatoka river on the island of Viti Levu, described in 1953 as a distinct species, is now regarded as a synonym.
