Damn you guys got some really beautiful s. ciliaris in Europe I have noticed.....I like that yellow mouth, why is it that the strophurus have either dark blue mouths or a bright yellow like this one? Pink is the usual mouth lining color on most geckos, but these are very unusual+interesting....

Why,I'm not sure but an hypothesis could be that the association of the mouth color with the spraying of their fluid could help to deter predators.
This might be effective mostly on diurnal predators but also this presume that their predators can detect this coloration. Most Strophurus have blue-dark blue inner mouth color, others yellow and S.elderi has the typical pink color.

Would this mean that the eurodactylodae which can squirt the same liquid has a similar mouth lining color, or another warning color type of defense adaptation?

I just think the inside color of the mouth is another attribute, but not linked directly with the spraying ability(the inside color of S.elderi is in no way impressive for exemple).
Now I don't really know the behavior of Eurydactylodes sp,in particular if they wide open their mouth when in front of a potential predator,nor if they exhibit any other particularity of that kind.

Very nice picture.
:shock: I don't expect that the yellow/orange is so bright !!

Fred & Oli : it seems that inner mouth coloration come from the behaviour's evolution of this genus. Due to the durnial activity of them, mouth coloration appears first with dark blue and evolved in some species in yellow. Like Fred said it's a benefit to affraid diurnal predators. This hypothesis was developped by J. MELVILLE, J.A. SCHULTE, A. LARSON.
The connection between coloration and diurnal behaviour is done by the ancestral evolution of a dark mouth coloration which can't affect seriously nocturnal predators.
This kind of attribute appears in some other species of the diplodactylinae (Saltuarius cornutus which is arboreal too).

Does they have the same (kind of) predators ?

Some interesting precisions can be found in the article, which was online a few months before, "A molecular study of phylogenetic relationships evolution of antipredator strategies in Australia Diplodactylus geckos, subgenus Strophurus"

Kei_on : I think so. S.c.ciliaris have dark blue mouth and S.c.aberrans have yellow mouth. To my mind, there are only S.c.abberans and S.taeniatus which express yellow mouth color.
