Tentacles on snails are sensory organs. They use them to feel around their environment. Also, the largest pair (or only pair, on those species that only have two tentacles) have a light-sensitive patch on them (sometimes at the tip, sometimes at the base)... the "eyes" of the snail. There are also olfactory sense cells (sense of smell) on the tentacles.

Snails have a sense of smell and taste. It is their best developed sense. The lower tentacles that are on either side of the mouth, stretch out in front of the snail as it moves. These tentacles have smell and taste receptors at their tips.
Are water snails hermaphrodites?
No. All apple snails are single sex which means you need a male and a female to produce offspring. Often apple snails are mistaken for ramshorn snails which ARE hermaphrodites and can actually mate with themselves when there are no other snails present. The easy way to tell the difference (because it can be confusing) is by looking to see how many sets of tentacles are present. Apple Snails will have 2 pairs of tentacles one large set and one smaller set attached near it's mouth. (4 tentacles total). Ramshorn snails will only have one set of tentacles. (2 tentacles total) One other feature that apple snails have is a breathing siphon that sticks out just under the shell at the left side of the head. They have both a lung and gills which helps when things dry up a bit or oxygen levels in their habitat are very low. This siphon is hard to spot but doesn't exist on ramshorn snails, which only have gills.
How many tentacles does a snail have?
Most snails, like many mollusks, have a ribbon-like structure called a radula in their mouths. Radulae have numerous rows of teeth, the exact number of which may vary. Some carnivorous snails eat the soft flesh of other mollusks after using their radulae to bore through the shells of their prey.
For an aquarium snail what do they look like?
Aquarium snails are different from regular land snails. All aquatic snails have gills. Just like their land relatives, these snails also have radula(rasping tongue),tentacles, and hard shells. Aquatic snails do not have as developed eyes as land snails. Many aquatic snails have a door or an opcerium at the entrance of their shell. Some aquatic snails also grow to the size of a baseball.
Why do snails have heads?
The feelers, to find where they're going, and the eyes, to see where they're going, are on the head.
