Movie 3.

Time-lapse thermal video (frame rate 1 Hz, playback rate 10 Hz) of a star-nosed mole grooming its nose. The star is not splayed open during grooming, and part-way through the video (Timestamp 08:11:48.5, UTC +0), a sudden rise in nasal ray temperature is evident. Since the front limbs are also warm during this video, it is not clear if heat is being transferred from the limbs or if this arises from vasodilation of the nasal rays.
