Unlike the eye stalk, the short snail's tentacles almost always point to the ground. They are mainly used to orient the sense of smell. The sensory cells on the surface of the tentacles give the snail a picture of its environmental odor and also help in the search for food.
Do snails have four limbs?
Snails do not have legs, but instead have one very large and flat foot. Snails secrete a layer of mucus and use it to glide. The snail's foot is not really a foot in the traditional sense, but a muscular organ that extends beneath the snail's body.
Do snails poop by mouth?
They don't poop by mouth. They poop from the middle of the body and it all comes out. One of these is a long, black, slimy sludge.
How many tentacles do snails have?
Most terrestrial snails have one or two pairs of tentacles on their heads.
Do snails have four hearts?
Snails usually have two ventricles, one atriosphere and one ventricle. Few groups have two atriums, and the heart is a three-chamber atrium. There is a valve between the atrium and the ventricle to prevent blood from flowing back. The snail cycle is basically open.
