Hi!
We are investigating the ability to use belly pattern of Great crested newts (Triturus cristatus) at larval stage for picture-matching in capture-recapture studies. Do you have 10 minutes for finding the 20 matches?

Background
Capture-recapture is the reference method for population estimate of newts, but its only based on reproductive adults (at least 2-3 years old). Using an underwater camera trap NewtCAM we are collecting belly images of newt larvae with a pattern, but it is unknown if it is unique and stable enough for picture-matching. Validating this would mean having the possibility to automate estimates of the reproduction success.
Instructions
The survey is in French but basically you need to find the match between the picture on the left and one of the 5 pictures on the right.
Select "Aucune correspondance" if you believe there is no match.
You have the possibility to see your results at the end.
Enjoy and do not hesitate to share the survey!

That looks great Xavier.
I´ll do my quiz!
Would be great to compare this later with the
Danube crested newt (Triturus dobrogicus) ;-)
