Common name: Twin Snapping Shrimp

General information

The Twin Snapping Shrimp, Alpheus soror, is a fascinating marine invertebrate known for its symbiotic relationships and unique snapping behavior. This species is characterized by its robust claws, one of which is typically larger and capable of producing a loud snapping sound. This sound is used for communication, defense, and hunting. The shrimp's body is usually translucent with a pattern of spots and stripes that can vary in color.

Care

In the aquarium, Twin Snapping Shrimp require a sandy substrate to construct burrows. They are generally hardy and can adapt to a range of conditions but prefer stable environments with plenty of hiding places. These shrimps are omnivorous and will accept a variety of foods, including frozen and pellet diets, but they particularly enjoy live or frozen meaty foods.

Reproduction

Twin Snapping Shrimp are known to form monogamous pairs, and the female carries the eggs until they hatch. The larvae go through several planktonic stages before settling and developing into juveniles. Breeding them in captivity can be challenging due to the need for specific larval rearing conditions.

Symbiosis

Alpheus soror often engages in a mutualistic relationship with goby fish, particularly species within the genus @species:amblyeleotris and @species:cryptocentrus. The shrimp maintains and shares a burrow with the goby, which stands guard while the shrimp is busy digging. This partnership provides the shrimp with protection, while the goby benefits from a safe home.

Habitat

This species is typically found in shallow tropical and subtropical marine environments, often associated with coral reefs and seagrass beds. They are distributed across the Indo-Pacific region, where they play a role in the ecosystem by turning over the substrate and influencing sediment composition.
