Euglandina rosea (Férussac, 1821) Mating In Situ And ?Cannibalism?
    In the roadside swale on the west side of US-1 about 3.3 miles northwest of International Golf Parkway, St. Johns County, Florida 3/3/2021. It appears that this mating aggregation began as a threesome but during the course of the event one or more of the larger specimens killed and devoured the smaller specimen (cannibalism). The nail polish mark on the spire is part of an experiment being conducted to ascertain the size of the Euglandina population as well as their movements within the study area.
