The Southern Hinge-back Shrimp, scientifically known as Rhynchocinetes australis, is a fascinating crustacean found in the coastal waters of the Southern Hemisphere.
Description and Characteristics
The Southern Hinge-back Shrimp boasts a distinctive appearance, with a flattened, somewhat triangular carapace, often featuring a reddish-brown coloration. It is also characterized by the presence of a prominent rostrum, a forward-projecting beak-like structure, and a pair of long, slender antennae. This shrimp can grow up to a maximum size of approximately 10 cm.
Habitat and Occurrence
This species is a common inhabitant of various marine environments. Rhynchocinetes australis can be found in algae zones, coral reefs, seagrass meadows, and eelgrass meadows. This wide-ranging habitat preference is attributed to its ability to thrive in the subtidal, sublittoral, infralittoral, and deep zones of the oceans from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. Therefore, the Southern Hinge-back Shrimp is considered a neritic species, as it occurs in the coastal zone of the ocean.
Taxonomy
The Southern Hinge-back Shrimp, Rhynchocinetes australis, belongs to the Class: Malacostraca, Order: Decapoda, and Family: Rhynchocinetidae. This classification places it within the group of crustaceans that includes lobsters, crabs, and other shrimp-like species.
Feeding
The Southern Hinge-back Shrimp is a carnivore, primarily feeding on a diet of smaller invertebrates and detritus. This adaptable feeding strategy enables it to thrive in a variety of habitats and utilize a range of food sources.
