Lysmata californica
(Stimpson, 1866)
red rock shrimp, lined shrimp
Lysmata californica is a caridean shrimp native to the East Pacific, commonly known as the red rock shrimp or lined shrimp. It inhabits shallow coastal of Southern California where it plays a role in benthic . The species has been studied for its behavioral responses to environmental stressors including ocean acidification and warming.

Habitat
Shallow coastal marine of Southern California. Seasonal and long-term changes in ocean pH and temperature are documented environmental factors in this .
Distribution
East Pacific; specifically recorded from coastal waters of Southern California. GBIF records also indicate presence in New Zealand, though this may represent introduction or misidentification.
Life Cycle
Molting is a critical life process; postmolt recovery periods have been studied under varying environmental conditions.
Behavior
Postmolt including feeding, cleaning behavior, and startle responses have been assessed in research contexts. These behaviors may be altered under ocean acidification and warming conditions.
Ecological Role
Described as a key in Southern California's shallow coastal , suggesting functional importance in local benthic .

Taxonomic Note
placement has varied between sources: Lysmatidae (GBIF, iNaturalist, Catalogue of Life) and Hippolytidae (NCBI, original Wikipedia description). This reflects ongoing taxonomic revision in caridean shrimp .
Research Context
A 2025 conference abstract (later withdrawn) investigated postmolt behavioral responses to combined pH (8.1 and 7.7) and temperature (12°C and 15°C) conditions over 50-day exposure periods. The withdrawal of this abstract limits confirmation of specific findings.
