The Filament-finned Prawn-goby, scientifically known as Stonogobiops nematodes, is a fascinating and relatively small fish species belonging to the Goby family (Gobiidae). This species is characterized by its distinctive filamentous fins and its intriguing symbiotic relationship with certain shrimp species, making it a captivating subject for marine enthusiasts and researchers alike.
Description & Characteristics
Stonogobiops nematodes typically reaches a maximum size of 6.0 cm, showcasing a relatively compact physique. Its body is elongated, with a slightly compressed shape, and its head is adorned with a distinct pointed snout. The most striking characteristic of this fish is its filamentous fins, particularly its dorsal and pectoral fins, which are elongated and stream-like, adding to its graceful appearance. The coloration of Stonogobiops nematodes varies depending on its environment, but it commonly displays shades of brown, gray, or tan with subtle patterns that aid in camouflage.
Habitat and Occurrence
Stonogobiops nematodes, the Filament-finned Prawn-goby, thrives in a diverse range of marine habitats, demonstrating a remarkable adaptability. Found in the subtidal, sublittoral, and infralittoral zones of the ocean, it is particularly prevalent in the neritic zone, the area extending from the lower limit of the intertidal zone to the shelf edge at approximately 200 m water depth. This species prefers sandy sea floors, where it can burrow and seek shelter amongst the sediment, making it a familiar sight in shallow coastal regions and even extending to deeper depths.
Taxonomy
Stonogobiops nematodes belongs to the Class: Teleostei, Order: Gobiiformes, and Family: Gobiidae. This classification positions it within a large and diverse order of fish, known for their unique adaptations and behaviors, including burrowing habits, symbiotic relationships, and a wide range of coloration patterns.
Feeding
The Filament-finned Prawn-goby’s dietary preferences are varied, encompassing a diverse array of small invertebrates. It is an opportunistic feeder, commonly consuming brine shrimp nauplii, brine shrimps, copepods, cyclops, daphnia salina, dustfood, flakes, frozen food (small varieties), mosquito larvae, pellets, and zooplankton. This varied diet reflects its adaptability to different environments and the availability of food sources in its habitat.
