I love reading about the different species of snails. I was fascinated to know that there are 3000 different speicies of snails and that they live up to 5-15 years long. I did not know that!!!
Nice site lots of articles and info good work. PS I didn’t know they had hands
They don’t have hands. They do have a foot. It is a way of explaining which way their shell opens and that has evolved over many millions of years. Yes, it’s fascinating.
Didn’t know they were rightys 🙂
I now know that snails don’t have brains, but they have groups of neurons.
Did you know that a Nobel Prize scientist, Eric Kandel, an American neuropsychiatrist who studied how memory works and how memory is stored in neurons, used a Mollusc similar to a snail, a sea slug [we call them sea hares] Aplysia californica, to study how neurons worked. He used it because he decided that this was the simplest group of animals known to be capable of learning.
It’s very interesting I was not aware snails had hands. I’d like to know what they use them for.
It was very interesting to find snails don’t have a brain but instead a ganglia.
