Very little is known about the habits and behavior of species of Grimpoteuthis. These photographs taken off Hawaii show an unknown species of Grimpoteuthis sitting on the ocean floor (right) and swimming with its fins just above the ocean floor (left). Some species, perhaps that in the title photograph, are very delicate and unlike the species seen on the right, may be entire benthopelagic.
