Detailed filmed observation of a case of cannibalism by the common wall lizard, Podarcis muralis (Laurenti, 1768)
Observation filmée d’une séquence de cannibalisme chez le lézard des murailles, Podarcis muralis (Laurenti, 1768)
Résumé
We here report the observation of a complete sequence of cannibalism by an adult male on a juvenile of the lacertid Podarcis muralis in the field in Haute-Savoie, a French department. That observation was not based on stomach contents as is often the case but was a visual observation which took place during most of the process from active prey capture to full prey ingestion during a time lapse of about 5 minutes. We here describe that observation and discuss its relevance for cannibalism occurrence in that species. A five minutes movie was made. Citizen science allowed that observation to be made widely available, and its potential as a new tool in natural history is highlighted.
