|---|---|
| Snails can sleep for up to three years | Snails are known for their ability to enter a state of torpor, where they can slow down their metabolism and remain inactive for extended periods of time. Some snails have been known to sleep for up to three years at a time. |
| Snails have the largest ratio of brain size to body size of any invertebrate | While snails are not known for their intelligence, they do have a relatively large brain compared to the size of their body. This is the largest ratio of brain size to body size of any invertebrate, which suggests that snails may be capable of more complex behaviors than is commonly believed. |
| Some snails are hermaphrodites | While most snails are either male or female, some species of snails are hermaphrodites, meaning that they have both male and female reproductive organs. This allows them to mate with any other individual of the same species, regardless of its gender. |
| Snails can regenerate lost body parts | Snails have the ability to regenerate lost body parts, such as their tentacles or even parts of their internal organs. This ability allows them to recover from injuries that would be fatal to other animals. |
