I took a longer video beforehand where it actively tried to intercept the ants, and even lunged at one point, but it kinda chickened out for 15 minutes after that, as in the video above

Addendum: now updated to include Palaeocentroscymnus bavaricus, described today by Feichtinger et al. (link.springer.com/article/10.1...), extending the previously Cenozoic genus into the Maastrichtian
Probably will be discussing this taxon a little more in a future blogpost...
