Gobiiformes is an order of ray-finned fish that includes the gobies. It is a highly diverse group, comprising over 2,000 species, making it one of the largest orders of fish. Gobies are typically small, benthic fish characterized by their fused pelvic fins, which form a suction cup-like disc used to adhere to substrates. They exhibit a wide range of adaptations to various aquatic environments, from freshwater streams to coral reefs and deep-sea habitats.

- Highly variable, ranging from drab browns and greys for camouflage to vibrant patterns and colors for display. Many species exhibit cryptic coloration to blend with their environment.

- Typically two dorsal fins; the first spiny, the second soft-rayed. In some species, they are continuous or very close together.
- Sirip ekor
- Rounded, truncate, or slightly emarginate caudal fin.
- Sirip dada
- Large and fan-like, often used for sculling and maneuvering.

- Pelvic fins are typically fused into a single, disc-like structure, located anterior to the pectoral fins, used for adhesion to substrates.
Tips Identifikasi
Pelvic Fins
Look for the fused pelvic fins forming a suction cup on the underside of the body, a key diagnostic feature for most Gobiiformes.
Dorsal Fins
Observe the presence of two distinct dorsal fins, though they may be very close or appear continuous in some species.
Body Shape and Size
Most gobies are small, elongated, and benthic. Size can range from less than 1 cm to over 50 cm, but the majority are under 10 cm.
Habitat
Their specific habitat (e.g., coral reef crevice, sandy burrow, freshwater stream) can help narrow down species identification.
Habitat
- Jenis air
- brackish
- Kedalaman
- From intertidal zones to abyssal depths (0-8,000 meters), highly species-dependent.
- Lingkungan
- Extremely diverse, including coral reefs, rocky shores, sandy bottoms, muddy estuaries, mangrove swamps, freshwater rivers, lakes, and even subterranean caves. Many are benthic, living on or in the substrate.
- Sebaran geografis
- Cosmopolitan, found in tropical, subtropical, and temperate waters worldwide, both marine and freshwater.

Fakta kunci
Symbiotic Relationshipsbehavior
Many goby species form fascinating symbiotic relationships, such as the 'shrimp goby' (Amblyeleotris spp.) which shares a burrow with a pistol shrimp (Alpheus spp.). The shrimp digs and maintains the burrow, while the goby acts as a lookout, warning the nearly blind shrimp of danger.
Smallest Vertebraterecord
The smallest known vertebrate in the world is a goby, Paedocypris progenetica, which measures only 7.9 mm (0.31 inches) at maturity. Another contender, Schindleria brevipinguis, is also a goby, reaching about 8 mm.
Mudskippersamazing
Mudskippers (family Oxudercidae, within Gobiiformes) are amphibious gobies that can spend significant time out of water, using their pectoral fins to 'walk' on land and breathing through their skin and mouth lining.
Adhesive Pelvic Finsevolution
The fused pelvic fins of gobies act as a powerful suction cup, allowing them to cling to rocks and other substrates in strong currents, a crucial adaptation for their benthic lifestyle.
Sex Changebehavior
Some goby species are protogynous hermaphrodites, meaning they are born female and can later change sex to male, often in response to social cues or the absence of a dominant male.
Informasi keamanan
Aman- Tingkat keamanan: safe
- Berbisa: Tidak
- Kelayakan konsumsi: edible
- Catatan penanganan: Most gobies are harmless. Handle with care to avoid stress to the fish. Some larger species may nip if threatened, but their bites are not dangerous to humans. Certain species, like some mudskippers, can be quite active and jump, so secure handling is advised.
Spesies serupa
Blennies
Blenniidae
Blennies typically have a single, long dorsal fin and separate pelvic fins that are often small and jugular (located under the throat). They lack the fused pelvic disc of gobies.
Dragonets
Callionymidae
Dragonets also have two dorsal fins and are benthic, but their pelvic fins are separate and thoracic, not fused into a disc. They often have a more flattened head and body.
Sleepers
Eleotridae
Sleepers are closely related to gobies but lack the fused pelvic fins. Their pelvic fins are separate, though often close together. They share a similar body plan and benthic lifestyle.
