BBC NEWS | Science/Nature | Sinister secret of snail's escape
article writes:
Snails with left-handed shells can have a big advantage in life - predators may find it impossible to eat them...They found the crab is unable to open left-handed shells because it only has a tool for peeling them on its right claw; so it discards them.
I'm unaware of how many major predators these snails have, but it would be interesting if we saw a marked drop off in RHS (Right Hand Snail) numbers
was hoping for "in the news" but couldn't find that forum :.
