The Storthynx Dwarfgoby, scientifically known as Eviota storthynx, is a small and fascinating fish species belonging to the goby family. This diminutive fish is characterized by its compact size and striking coloration, making it a captivating subject for marine enthusiasts and researchers alike.
Description & Characteristics
The Storthynx Dwarfgoby (Eviota storthynx) is a remarkably small fish, reaching a maximum size of only 2.5 cm. Its body is typically slender and elongated, with a slightly compressed profile. The dorsal fin is composed of two distinct parts, the first being a small, spiny fin followed by a longer, soft-rayed fin. The anal fin is also elongate and situated behind the dorsal fin. The caudal fin is rounded and provides propulsion for this agile fish. The overall coloration of the Storthynx Dwarfgoby can vary depending on its habitat and individual variations, but it usually features a combination of bright orange, yellow, and brown hues.
Habitat and Occurrence
The Storthynx Dwarfgoby (Eviota storthynx) is a predominantly reef-associated species, residing in the warm waters of the Indo-Pacific region. Its distribution extends across a vast geographical range, encompassing the coral reefs of the tropical Western Pacific Ocean. This species is commonly found in shallow, coastal waters, typically residing at depths ranging from the intertidal zone to around 20 meters.
Taxonomy
The Storthynx Dwarfgoby (Eviota storthynx) belongs to a diverse family of fish known as the Gobiidae. This family is part of the larger Order Gobiiformes, which encompasses a wide array of goby species. The Gobiiformes, in turn, are classified within the Class Teleostei, a vast group of ray-finned fishes that represents the majority of fish species found in the world’s oceans and freshwater bodies.
Feeding
The Storthynx Dwarfgoby (Eviota storthynx) is a small, opportunistic feeder, primarily consuming small invertebrates and zooplankton. Its diet consists of a variety of organisms, including brine shrimp nauplii, brine shrimps, and other minute creatures found within its reef habitat. This feeding strategy is characteristic of many goby species, highlighting their role as essential components in the complex food web of the marine environment.
