Caridina mariae, commonly known as the tiger shrimp, is a variety of freshwater shrimp from Southeast Asia (neighboring counties of Yingde and Conghua, Guangdong Province, Southern China and Hong Kong SAR[1]) that are popular in hobby aquariums.

The natural coloration of the shrimp isa semitransparent body, with dark brown to black blotches on the carapace, and dark brown to black "tiger" stripes along the posterior part of the carapace and along the first six abdominal segments.

[2] At full size, these shrimp reach about 1–1.5 in (25–38 mm) in length, with females of the species being larger than the males, and having a curved underbelly.

Their larval stage is well-developed and resembles the adult with functional walking pereiopods and swimming pleopods.
