Source-derived summary

The grass goby (Gobius ophiocephalus) is a species of goby native to the Mediterranean Sea, the Sea of Azov, and the Black Sea. It is sometimes classified as the only member of the monotypic genus Zosterisessor.

Characteristics

Grass gobies can grow up to 29.9 cm (11.8 in) long. The head crown, nape, throat, belly, and bases of the pectoral fins are covered by cycloid scales and the gill covers are naked. The abdominal sucker has no blades and does not reach the anus. The mandibulae are protrusive, and the skin soft, with mucus. Their coloration is green-brown, patterned with merging brown spots. The cheeks have round light spots. The dorsal, caudal, and pectoral fins have longitudinal brown stripes on a light background; the anal and abdominal suckers are dark.

Range

Widespread in coastal waters of all seas of the Mediterranean basin, they are especially numerous in the northern Adriatic Sea, Venetian Lagoon, and Sète Lagoon (France) and in the Black Sea near all coasts, especially in lagoons and estuaries of the north-west, Varna and Burgas Bays, Sea of Azov, and Sivash.

Editorial summary

The public source identifies “Grass goby” as species of fish. This brief keeps that definition visible, then builds a research path around Grass, goby and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 181-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Grass, goby and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Grass goby”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 29, 2025. The linked authority identifier is Q745561. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
