I collected this skeleton shrimp from some algae and have not been able to match it to typical mediterranean endemic and invasive species. Have considered: Caprella acanthifera, C. dilatata, C. equilibra., C. septentrionalis, C. scaura, and Paracaprella pusilla. Would love some expert opinions! He is now living in my self-sustaining jarrarium. I have more images, so just let me know if there's a specific area I could focus on.
