Three things to know

  • Large males can have blue claws.
  • Adults are omnivores.
  • Larvae require brackish water.

Habitat and range

Giant river prawns inhabit tropical freshwater connected to brackish estuaries. The FAO source uses a historical species treatment and also describes farmed populations beyond the original range.

Appearance and adaptations

A long rostrum projects from the head, and large males may develop exceptionally elongated blue claws. Long antennae and stalked eyes explore the surroundings.

Diet and behaviour

Adults eat both plant and animal material. Females release larvae in brackish water, while later stages move towards a bottom-dwelling freshwater life.
