Crazy crayfish hangs on a glass thermometer
It’s a video of a young Mexican Orange Dwarf crayfish (Cambarellus Patzcuarensis var. orange ) handing on a glass thermometer.
The most unexpected thing that it was able to hold itself there for quite a long time. Take into account that crayfish has no suckers and glass thermometer tube is smooth.
Anyway, it was able to balance like that for at least several minutes.
