Do snails pee?

While water snails excrete a very much diluted primary urine, terrestrial pulmonate snails have developed the ability to resorb most of the water. In terrestrial snails, excretion takes place in a kidney, whose interior surface has been increased by many interior walls called septae.

How can you tell how old a snail is?

While the baby grows and develops it stays in a nest near its parents for about 3 months before it is ready to go off into the world on its own.

Do snails clone?

During a process called parthenogenesis, cell division allows the unfertilized female gamete to develop without auto- or sexual fertilization. This results in a clone, or an exact replica, of the parent snail.
