## Snakeskin Wrasse
### Taxonomy and Nomenclature
The snakeskin wrasse is scientifically classified as *Eupetrichthys angustipes*. It belongs to the family Labridae, which encompasses a diverse group of wrasses known for their bright colors and complex behaviors. The genus *Eupetrichthys* is monotypic, containing only this single species. The species was first described in 1885 by the ichthyologist Albert Günther.
The common name „snakeskin wrasse” derives from the fish’s distinctive body pattern, which resembles the mottled, scaled appearance of snakeskin. This pattern provides effective camouflage against the rocky and seaweed-covered substrates it inhabits.
### Description
The snakeskin wrasse is a relatively small fish, typically reaching lengths of up to 15 centimeters (approximately 6 inches). Its body is elongated and laterally compressed, facilitating maneuverability within its benthic environment. The coloration is variable but generally consists of a pale base color overlaid with irregular dark blotches and reticulations that mimic the appearance of snakeskin.
The head is relatively small with a pointed snout and a terminal mouth equipped with small, sharp teeth adapted for grasping small invertebrates. The dorsal fin is continuous, with spiny and soft-rayed portions, while the anal fin is shorter but similarly structured. The pectoral fins are rounded and used for precise movements along the substrate.
### Distribution and Habitat
The snakeskin wrasse is endemic to the temperate coastal waters of southern Australia, including regions off South Australia, Victoria, and Tasmania. It inhabits shallow rocky reefs, seagrass beds, and areas with abundant macroalgae, typically at depths ranging from 5 to 30 meters.
This species favors habitats with complex structures that provide shelter and feeding opportunities. The mottled coloration allows it to blend seamlessly with the rocky and algal environment, aiding in both predator avoidance and ambush predation.
### Behavior and Ecology
#### Feeding
The snakeskin wrasse is a carnivorous species that primarily feeds on small benthic invertebrates. Its diet includes crustaceans such as amphipods and small crabs, mollusks, polychaete worms, and occasionally small fish. It employs a foraging strategy that involves searching among rocks and algae, using its sharp teeth to extract prey from crevices.
#### Reproduction
Like many wrasses, the snakeskin wrasse exhibits complex reproductive behaviors, including protogynous hermaphroditism, where individuals may change sex from female to male during their lifespan. Spawning typically occurs in the warmer months, with males establishing territories and courting females through displays of color and movement.
Eggs are demersal and adhesive, laid on substrates within the male’s territory. After hatching, larvae are planktonic, drifting with currents before settling to the benthic habitat as juveniles.
#### Social Structure
Snakeskin wrasses are generally solitary or found in small groups. Males may be territorial during the breeding season, defending areas that provide optimal conditions for spawning and feeding. Outside of breeding periods, individuals are less aggressive and more cryptic.
### Conservation Status
Currently, the snakeskin wrasse is not listed as threatened or endangered. Its populations appear stable within its natural range, and it benefits from the relative protection of temperate reef habitats. However, like many coastal species, it could be susceptible to habitat degradation caused by pollution, coastal development, and climate change.
### Importance to Humans
The snakeskin wrasse is not a target species for commercial fisheries due to its small size and cryptic nature. It may occasionally be collected for the aquarium trade, although it is not widely popular compared to more colorful tropical wrasses. Its role in the ecosystem as a predator of small invertebrates contributes to the health and balance of benthic communities.
### Research and Study
Scientific interest in the snakeskin wrasse has focused on its ecological role within temperate reef systems and its reproductive biology. Studies of its camouflage and behavior contribute to broader understanding of predator-prey interactions and adaptation in marine fishes.

## Summary
The snakeskin wrasse (*Eupetrichthys angustipes*) is a small, benthic fish native to southern Australian coastal waters. Recognizable by its snakeskin-like pattern, it inhabits rocky reefs and seagrass beds where it preys on small invertebrates. Exhibiting complex reproductive behaviors and a cryptic lifestyle, it plays a vital role in temperate marine ecosystems.
