Bamboo Shrimp

Introduction: Bamboo shrimp are freshwater decapod crustaceans known for their specialised fan-like appendages, which they use to filter suspended food particles from flowing water.

Key pointers

  • Scientific name: Atyopsis moluccensis is a commonly recognised bamboo shrimp species.

  • Biological group: Arthropoda, class Malacostraca, order Decapoda.

  • Feeding adaptation: Uses modified fan-like setae on its front appendages to capture microscopic food particles from the water.

  • Habitat: Freshwater streams and rivers, particularly environments with suitable water flow.

  • Ecological role: Participates in aquatic food webs and processes suspended organic particles.

  • Adaptation: Fan feeding is an example of specialised filter-feeding behaviour.

  • Biodiversity relevance: Freshwater species may be affected by pollution, altered stream flow and habitat degradation.

UPSC focus: Bamboo shrimp are animals, not plants. Their filter-feeding adaptation distinguishes them from many shrimp that primarily forage on the substrate.
