Gnatholepis gymnocara, the Nakedcheek sandgoby, is a small species of ray-finned fish in the subfamily Gobionellinae. [1] The Naked cheek sandgoby is found primarily in the Indian Ocean along the coast of Australia . [1]
The "naked cheeks," which serve as the namesake of this species, are one of the most diagnostic features of the Nakedcheek sandgoby. Scales are totally absent on the cheek and operculum, back to the predorsal midline, though there are a few typical cycloid scales on the base of the pectoral fin and on the breast. [2] While a small fold might be present on the end of the lower lip, there is no truly distinct flap on the lower lip, which is also common in other goby species. There are also no teeth with are distinctly larger than the rest of the dentition. [2]
Males of this species reach a maximum length of 3.7 cm in total length. [3] Their bodies are pale tan/dusky with a 6 darker dusky blotches, and a row of horizontal spots and streaks. [2] There is also an irregular dark, cross-shaped blotch on each cheek that extends downward from the eye. [2] There is a small brown spot at the base of the caudal fin that is approximately the width of the pupil. Males also have a small dark spot at the base of the first dorsal fin, while females lack this feature. [2]
The Nakedcheek sandgoby is found in the western Pacific Ocean, specifically Australia. [1] It can be found in shallow, nearshore marine environments between 0 and 1m in depth. [3] Specimens are typically collected from around 0.5m deep and, while most are found in marine waters, at least one has been collected from a brackish habitat. [1]
The red morwong, also known as the sea carp, is a species of marine ray finned fish traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found off southeast Australia and the North Island of New Zealand from shallow depths to at least 55 m, on rocky reef and coastal areas. Its length is between 30 and 60 cm.
The sand goby, also known as a polewig or pollybait, is a species of ray-finned fish native to marine and brackish European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres. This species can reach a length of 11 centimetres (4.3 in) TL. This species is sometimes kept in public aquariums. The sand goby is of a sandy colour, with darker markings on the sides and a creamy-white underside. In the breeding season the male fish has blue spot at the rear of the first dorsal fin, ringed with white. The fish has a slender body, and the head is about a quarter of the total length.
Platycephalus fuscus, the dusky flathead or black flathead, is a large predatory fish and the largest member of the family Platycephalidae. Dusky flathead are a largely estuarine species and are found in estuaries, estuarine lakes and coastal bays on the east coast of Australia, from Cairns in Queensland to the Gippsland Lakes in Victoria. They occur over sand, mud, gravel and seagrass and can inhabit estuarine waters up to the tidal limit.
The black goby is a species of ray-finned fish found in the Eastern Atlantic and Mediterranean Sea and Black Sea. It inhabits estuaries, lagoons, and inshore water over seagrass and algae. It feeds on a variety of invertebrates and sometimes small fish. This species can also be found in the aquarium trade.
The dwarf pygmy goby or Philippine goby is a tropical species of fish in the subfamily Gobionellinae from brackish water and mangrove areas in Southeast Asia. It is one of the smallest fish species in the world. Males reach maturity at a standard length of 0.9 cm (0.35 in) and can reach up to 1.1 cm (0.43 in) in standard length, while the females can grow up to 1.5 centimetres (0.59 in) in total length. Adults weigh around 4 milligrams (0.00015 oz). It is known as bia and tabios in the Philippines.
Butis butis, the crazy fish, duckbill sleeper, or upside-down sleeper, is a species of sleeper goby that are native to brackish and freshwater coastal habitats of the Indian Ocean and the western Pacific Ocean from the African coast to the islands of Fiji. They prefer well-vegetated waters and can frequently be found in mangrove swamps. They are small, drably-colored fish, reaching a maximum length of only 15 cm (5.9 in). They are predatory and are known for their behavior of swimming vertically – or even upside down – while hunting.
The camouflage grouper, also known as the blue-tailed cod, camouflage rockcod, small-toothed rockcod, smooth flowery rock-cod, snout-spot grouper or snout-spot rock-cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has a wide Indo-Pacific distribution where it is associated with reefs.
The coachwhip trevally, also known as the oblong trevally or oblique-banded trevally, is a species of inshore marine fish classified in the jack family Carangidae. The coachwhip trevally is distributed through the Indo-west Pacific region, ranging from South Africa in the west to Fiji and Japan in the east. It is a moderately large fish, growing to a known maximum length of 46 cm and can be distinguished from similar species by an array of detailed morphological features including dentition, fin ray counts and scale patterns. The coachwhip trevally inhabits coastal waters throughout its range, known to prefer estuarine waters in a number of localities. Nothing is known of its diet or reproductive biology, and is of little importance to fisheries, occasionally taken as bycatch in trawl and hook and line fisheries.
The barcheek trevally, also known as the barcheek kingfish, shortridge trevally or oblique-banded trevally, is a species of moderately large marine fish of the jack family Carangidae. The barcheek trevally is distributed throughout the tropical waters of the Indo-west Pacific region, ranging from South Africa in the west to Japan, Australia and a number of small central Pacific islands in the east. The species inhabits inshore and offshore waters, found along the slopes of lagoons and out to deeper reefs on the continental shelf, where it preys on small fish and benthic crustaceans. It is a moderately large fish, growing to a maximum recorded length of 50 cm, and can be distinguished from similar species by its somewhat protruding lower jaw and the dark banding on its operculum. It is of minor importance to fisheries throughout its range, taken by trawling, hook and line methods and various inshore fish netting methods.
The longfin grouper, also known as the longfin rockcod, bar-breasted rock-cod, Gilbert's rock-cod, honeycomb rockcod, spotted groper or wirenet cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Western Pacific Ocean.
The largetooth goby, also known as Wilbur's goby, is a species of ray-finned fish from the family Gobiidae which is native to the Indo-Pacific from the Seychelles to Micronesia. Its known range has been extended to the Red Sea as specimens were photographed at one site and collected at another site off Egypt. This species lives in sheltered marine waters at depths of from 0 to 20 metres preferring areas with sandy substrates. This species grows to a length of 6.5 centimetres (2.6 in) SL. This species is the only known member of its genus. This species is not obviously sexually dimorphic and it has a background colour of pale brown to greenish-brown and a pale ventral side. The body is marked with brown and white spots, pairs of larger brown spots create a mid-lateral row along its flanks and there is a dark spot on the caudal fin peduncle. It has a brown blotch on the cheek and a series of short brown bars along its back. The largetooth goby is a solitary fish which is found in coastal bays, lagoons and estuaries over fine sandy substrates close to the margins of reefs or silt beds in the vicinity of sheltered and often turbid coastal reefs. It is most frequently collected from shallow waters to 7 metres (23 ft), around coral reefs but off southern Japan, the largetooth goby occurs at the bottom of sandy bays. The specific name honours the American physician, Ray Lyman Wilbur (1875–1949) who was president of Stanford University from 1916–1943, as well as being the United States Secretary of the Interior from 1929–1933. Wilbur helped the author, Herre, get to Palau, the type locality of this species.
