Male octopuses have a specialized arm (the hectocotylus) which transfers sperm to a female, whereas squid mate in large groups. In the skin, there are pigment cells (chromatophores) which can be guided This shell is large enough for the snail to completely retract into for defense. the retina point into the inner space of the eyeball, towards the incident [citation needed], Snails and slug species that are not normally eaten in certain areas have occasionally been used as famine food in historical times.
