It swims facing backward by open­ ing and closing its two-piece shell. It is surprisingly fast.

Silver

Grains of sand trapped in its shells mix with its body fluids to form beautiful pearls.

Crystal

Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.
