Diagnostic Description

provided by CoralReefFish

Diagnosis: Modal fin-ray counts of D-VI,14 and A-15 indicate Gobionellus oceanicus. This genus typically has one more anal-fin ray than second-dorsal-fin rays (sometimes equal). A number of other species have spent some time in this genus, but Pezold 2004 recognizes only one Caribbean species. (U) G9

Comprehensive Description

provided by CoralReefFish

Description: Body thin, very long, and narrow with a small eye and a pointed snout with a terminal large mouth. Pectoral and pelvic fins long relative to the head (but short compared to the long body), extending more than halfway to the vent. Dorsal and anal-fin bases very long, caudal peduncle short, . Lightly marked along the lower body: melanophores usually in streaks at the isthmus (often missing) and at the pelvic-fin insertion, internally at the dorsal surface of the swim bladder and around the gut near the vent, and in a row along the anal-fin base, often variably present and variably paired (can occur on either side unpaired). In many individuals the surface melanophores are indistinct or some are missing. Series of transitional larvae show development of the eye from a markedly narrowed vertical oval with a flattened base, the pupil off-center dorsally, and a pronounced slant backwards to large and round. The head profile develops from a thin pointed head to a blunt snout with an almost sub-terminal mouth. Transitional larvae first develop patches of tiny iridophores on the top of the head and in a stripe behind the eye and then a scattering of large discrete melanophores on the head. Body markings include a lateral row of melanophores on each side of the gut strip along the abdomen. Melanophores develop in patches spaced out along the base of the dorsal fin, on the caudal peduncle, and at the base of the central caudal-fin rays.

Diagnostic Description

provided by Fishbase
This species differs from its congeners by the following characters: mouth terminal and oblique; most distinct pigmentation, a large blotch on trunk located anterodorsally beneath pectoral fin; opercle with a triangular patch; pectoral-fin base with a blotch; second dorsal-fin 14 elements, anal fin with 15 elements; dorsal fins separate; adults with small ctenoid scales covering trunk and nape, 57-89 scales in a lateral series; upper jaw with several rows of teeth; first gill arch with 8 thin rakers on ceratobranchial, 1at the angle, and 6 or 7 on epibranchial (Ref. 55435).

Migration

provided by Fishbase
Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Biology

provided by Fishbase
Adults are found on shallow mud or mud-sand bottoms in turbid and generally brackish water near estuaries (Ref. 13628). Also encountered in weedy backwaters (Ref. 7251) and hyper-saline waters (Ref. 13628) with salinity ranging from 0.15 to 37.2 ppt (Ref. 97140).

Gobionellus oceanicus

provided by wikipedia EN

The highfin goby (Gobionellus oceanicus) is a species of fish belonging to the family Gobiidae.

Description

The highfin goby has a very long, thin body with a rounded snout. The species has a number of lightly marked lateral streaks along its body, called melanophores, which are variably present and variably paired on both sides of the body. Usually, the markings are indistinct and missing certain stripes.

Distribution and habitat

The highfin goby ranges north from Virginia, and rarely New Jersey, to southern Brazil. The species can be found in both freshwater and brackish water ranging in temperature from 11 °C - 29 °C
