Predation On Euglandina rosea (Férussac, 1821)

    Being a large carnivorous species at the top of the snail food chain, Euglandina rosea has nothing to fear from any other terrestrial species. However, in areas with a substantial Euglandina population it is not unprecedented to discover the species practicing cannibalism. This usually involves a large specimen devouring a much smaller snail. Cannibalism is much more easily observed when two dissimilar sized Euglandina specimens are kept in captivity in a single terrarium. In the field, unless witnessed, this cannibalism would go undetected as the only evidence that anything was amiss would be the presence of an empty shell. However, in the case of predation on Euglandina by presumably a terrestrial warm blooded mammal such as a rat, evidence of the event is occasionally found such as is illustrated below.  In many cases though (see page two) the evidence of predation is not nearly as clear cut.
