Do snails have feelings?
In summary, snails might have the biochemical potential to feel love, but they might not have a socially-mediated evolutionary reason to feel love. They engage in reproductive behaviors, but we don't know whether they feel love or pleasure during reproduction.
Snails may have opioid responses and mussels release morphine when confronted with noxious stimuli. Both reactions suggest that these animals do, in fact, feel pain. While mollusks don't have brains per se, they do exhibit some nervous system centralization. They have several pairs of ganglia connected to a nerve cord.
“We tested memory ability in individual pond snails across a range of tasks including memory of what is good or bad to eat, and predator avoidance. This revealed that individuals who are good at one type of memory are generally very poor at other types of memory.” The study is published this week in Scientific Reports.
When snails sense danger around them, they hide into the shell. The head, at one end of the body, has one to two pairs of tentacles (retractable and provided with tactile receptors), which have the eyes at the tips. The lower pair works as olfactory organs to smell.
Do snails recognize humans? Snails have very bad eyesight so they won't recognize you by sight. But, their sense of smell is quite good and they will begin to recognize how you smell.
A: Yes, snails can see. For most North American land snails, the eyes are located at the ends of the two upper (longer) tentacles. In a few species, the eyes are located at the bases of these tentacles. The snails' eyes are fairly advanced, with lenses that can focus, similar to the lenses in our eyes.
We all know that frightening experiences give us powerful memories. Now, researchers at the University of Calgary have demonstrated that an invertebrate is also capable of learning from fear. They published their findings in The Journal of Experimental Biology earlier this month.
(2.) No. We can also imagine, I think, that the answer is no, snails entirely lack sensory experiences of any sort -- and thus, presumably, any consciousness at all, on the assumption that if snails are conscious they have at least sensory consciousness.
“Slugs and snails are extremely dependent on a high water content in their bodies. They constantly need water to replenish any the lose. “We don't know how much pain they feel when in contact with salt, but a slug or snail caught in granules will try to wiggle away while exuding a lot of mucus to clean their skin.”
They, just like other animals (including humans), remember things about different aspects of their environment. They remember smells that are associated with good things to eat, for instance, as well as negative experiences which may be associated with the risk of being eaten themselves.
Do snails poop on their head?
Snails have a foot for a body. With such an unusual physique and a need to get rid of waste after eating food, how do snails poop? Snails poop from their anus, which sits inside their shell towards the front of their body (on the same side as their head).
The cerebral ganglia of the snail form a primitive brain which is divided into four sections. This structure is very much simpler than the brains of mammals, reptiles and birds, but nonetheless, snails are capable of associative learning.
Answer: The snail which had been the fastest creature, had become, due to his own selfishness, the slowest.
Snails consist of blood to 20 to 50 %, the sea hare's (Aplysia) body weight is about 75 % blood. Most snails' blood pigment is haemocyanin. Contrary to haemoglobin, used by vertebrates, haemocyanin works on a complex with copper as oxygen binding atom.
“You and a super intelligent snail both get 1 million dollars, and you both become immortal, however you die if the snail touches you. It always knows where you are and slowly crawls toward you.

"It's one of those things that drives you to avoid those [painful] things in the future," he said. But animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers.
(2.) No. We can also imagine, I think, that the answer is no, snails entirely lack sensory experiences of any sort -- and thus, presumably, any consciousness at all, on the assumption that if snails are conscious they have at least sensory consciousness.
Yes, slugs can feel pain, but probably not in the same way that humans do. While slugs (Limax maximus) have a nervous system they lack some key components to feel pain as we do. The evidence is clear that slugs react to outside stressors, like salt, heat, electricity, even human touch.
Let's just take things slowly: Snails appear to be kissing as they cross one another's paths on a log. It was never likely to be a whirlwind romance, but the courtship between these two looks like it's moving at a snail's pace.

Wash your hands thoroughly, and practice good hygiene. Don't handle snails. Make sure snails, crustaceans, and frogs are thoroughly cooked before eating them.
