Macroscopic, histological and toxicological aspects of early Gammarus pulex scavenging.

Two cases of scavenging postmortem freshwater shrimps (Gammarus pulex) are presented. We report the two first illustrated observations of cutaneous postmortem injuries inflicted by a G. pulex population, a small freshwater crustacean, on two non putrefied drowning victims, and we describe their particular histological features and their potential in forensic investigations.
