Flamingo Tongue Snail The flamingo tongue snail's bright, giraffe-like pattern often tricks amateur shell collectors into thinking they've found a colorful shell. In fact, the shell is really white; it's the snail itself that has the striking design. The snail spreads its mantle tissue over the shell, giving it the funky look. When threatened, it recedes into the shell. The flamingo lives on Caribbean and Atlantic coral reefs at a maximum depth of 100 feet.
