Cephalopod Mantle Armature
Richard E. Young, Michael Vecchione, and Katharina M. Mangold (1922-2003)
Cephalopoda Glossary
The skin of the mantle sometimes contains large scale-like structures called cushions, tubercules or warts depending on their shape and structure. The function of these structures is uncertain but a protective role seems likely. A hydrodynamic role is also possible in some species such as Pholidoteuthis boschmai (see Roper and Lu, 1990). In addition many other species possess very small tubercules in the skin that are only visible under the microscope. However, sometimes even the large structures are easily overly looked due to their transparency (Fig. A) and their tightly packed arrangement (Fig. B).
