Description & Characteristics
Alpheus paracrinitus is a relatively small snapping shrimp, typically reaching a maximum size of approximately 20 mm.
Habitat and Occurrence
Alpheus paracrinitus is a marine species commonly found in the Indo-Pacific region. These shrimps are typically found in intertidal and shallow-water habitats, often inhabiting areas with soft sediments such as sand or mud. They can be found in the neritic zone, which is the coastal zone extending from the shoreline to the edge of the continental shelf.
Taxonomy
Alpheus paracrinitus belongs to the class Malacostraca, which comprises a diverse group of crustaceans including lobsters, crabs, and shrimp. Within this class, Alpheus paracrinitus is further classified under the order Decapoda, a group characterized by ten walking legs. The family Alpheidae, to which Alpheus paracrinitus belongs, is known for its members’ distinctive snapping claws.
Feeding
Alpheus paracrinitus is an opportunistic carnivore. Its diet primarily consists of small invertebrates such as worms, crustaceans, and mollusks. The shrimp’s powerful snapping claw is essential for hunting and capturing prey. The loud snapping sound produced by the claw can stun or even kill small animals, making it an effective hunting strategy.
