Hypobranchial gland

The hypobranchial gland is a glandular structure which is part of the anatomy of many mollusks, including several different families of gastropods, and also many protobranch bivalves.[1] This gland produces mucus as well as biologically active compounds. The cephalopod ink sac is a modified hypobranchial gland.[2]
