Amazingly, certain research has stated that hermit crabs are ready deleting alive gastropods from their shells (e.grams., Brightwell, 1951, Brightwell, 1953, Randall, 1964, Rutherford, 1977).

Rotjan). The goal of today’s studies would be to explore behavioral experiments from the lab and field, where crabs was basically paired with gastropods in various points, to resolve a fundamental concern regarding the wider ecology of your hermit clade: exactly how constrained is hermit crabs within their power to obtain the shells which might be very important to their endurance and you may reproduction?
