What group is a snail in?
Mollusca, and then in class Gastropoda ('belly feet', after the muscular foot they crawl on).
I don't think in any way they are, my list below shows their differences. A cheetah is way more faster than a snail. A snail is in the animal group called Mollusks and the cheetah is in the Cat family. A snail carries its home and a cheetah finds one. Cheetahs have beautiful patterns and snails don't. This list can go on and on, hope I helped.
The two tentacles that stick out are the eyes of the snail. The two lower and smaller tentacles on the sides of a snail are their feelers. Don't touch their tentacles and make the snail feel safe and secure in their habitat. Don't handle your snail/snails roughly and be sure that the things you do to the snail or to the habitat will be safe to the snail.
