Rhynchocinetes durbanensis, commonly known as the hingebeak prawn, is a species of shrimp (family Rhynchocinetidae) found in the Indo-Pacific. Up to 4 cm (1.6 in) in length, the shrimp has large black eyes, and features red and white lines on a translucent body. It has many white ocelli (spots) as well as a Y-shaped white mark on the upper front part of its carapace. It is strongly sexually dimorphic, and dominant males have larger first pair of chelipeds.[1] The shrimp is found in hollows and crevices from 5 to 35 metres (16 to 115 ft) deep, where it forms groups consisting of dozens of individuals.[2] One study determined that the ovigerous females carry from 267 to 1764 eggs, and the eggs take 9 days to hatch after spawning at a temperature of 29.2 °C (84.6 °F), or 18 days when the temperature is under 22.0 °C (71.6 °F).[3] R. durbanensis has been frequently confused with R. uritai,[4] and also closely resembles R. brucei.[2] R. durbanensis was first described scientifically by Isabella Gordon in 1936.[5][6]
