|Big male, showing off his snail cracking tool.|
|Asian mud snails, up on the glass where the crabs can't get them.|
These two snails are survivors, and bear their scars proudly. The lower one has had the worst of it; extensive damage near the lip, where the crabs prefer to start work, and a large patch taken out of the upper spiral. Lucky for her that their shells are so thick. Or rather, it's an arms race; if your enemies have humongous shell-cracking pincers, you'd better wear heavy armour and keep it repaired. Climbing walls helps, too.
The snail on the right has patched the big gap in her shell; only the scars remain.
|Lips, patched and freshly broken.|
The snails won this round.
