Multigenerational immune priming in an invertebrate parthenogenetic Artemia to a pathogenic Vibrio campbellii

• Invertebrates rely on the innate immune system to fight against pathogens.
• The adaptivity or memory of immune responses is the hallmark of only vertebrates.
• Invertebrate is assumed to have immune memory similar in kind to that in vertebrate.
• We provided evidences of memory-like phenomenon in the invertebrate Artemia.
