Hancock's organ
Hancock's organ is a lateral concealed sensory organ of gastropods,[1] a chemo-sensory sense organ found in some sea snails.[2] This organ is found in most of the shelled opisthobranchs.[2]
A great majority of the bubble shells and sea slugs of the orders Acteonoidea and Cephalaspidea have Hancock’s organs.
