32 ONYCHOTEUTHIDA. 
These animals are solitary in habit, frequenting the open sea, 
and especially banks of gulf-weed. Some of the species have an 
immense geographical distribution; as O. Banksii, from the 
Arctic Ocean to the Cape of Good Hope and Indian Ocean. The 
peculiar arrangement of suckers, forming a circle at the base of 
each tentacular club, enabling the animal to use the two clubs in 
conjunction when necessary , give an immense increase of power. 
They suggested the obstetric forceps of Professor Simpson.
