I can't conceive of what biological necessity or selection pressures would cause a line of skinks to develop blue tongues. Fascinating.

Credit for skink, blue Harlequin shrimp, the blue-spotted Leopard moth, and the molting ?gecko.

    Giraffe's have blue tongues as do the Australian blue tongue lizard

    Interesting. Some blue colors could be due to venous blood, but others must be active pigments.

    I know little about geckos, but I'd be willing to bet that blue tongues are due to sexual pressure, like peacock's tails and frigate bird chest balloons.
