list of baby snails look at the shell the protoconch at the moment the shell is still very
thin that's because the snail hasn't eaten lots of food with calcium in it yet to make the shell hard
and can you see the slippery mucus underneath the baby snail's body when something's slippery we say
that it has less friction a bit like this if i rub my hands together friction stops them from moving
too quickly but if i add some hand lotion look the slippery lotion makes it much easier to move them
back and forward just like the snail's foot and the slippery mucus help the snail to move forward
but to understand how the foot and the mucus work together i think we should use one of my special
cameras chris has put a garden snail on a clear sheet and i've attached
this to my special camera it's called a probe lens
and it's going to help us see underneath the snail's foot in more detail okay chris
wow that is all of the mucus and i can see it there
it makes the surface slippery so it's easier for the snail to glide along this is incredible
but a snail needs more than mucus to move can you see the snail's body ripples as it moves forward
those ripples are the snail's muscles working to help it move
the snail is squeezing and relaxing its muscles over and over wow watch more on bbc iplayer
