Description edit
The size of the shell of an adult varies between 55 mm and 120 mm. The snail's salivary glands contains the toxin tetramine (tetramethylammonium ion).[2] The male shell tends to be smaller and more slender than the female shell. The interior of the peristome in male specimens is characterised by a reddish orange colour, while in female specimens it is whitish or yellowish.[3]
Distribution edit
This species is found in the Pacific Ocean off the coasts of Japan.
