The Wet-Dog Shake: How wet mammals dry themselves
The drying of wet fur is a critical to mammalian heat regulation. This fluid dynamics video demonstrates how hirsute animals rapidly oscillate their bodies to shed water droplets, nature's analogy to the spin cycle of a washing machine.
High-speed videography and fur-particle tracking is employed to determine the angular position of the animal's shoulder skin as a function of time. X-ray cinematography is used to track the motion of the skeleton. Particular attention is paid to rationalizing the relationship between animal size and oscillation frequency required to self-dry.

i dry myself like this too.is it weird?
ReplyDeleteSweet vid, man. The X Rayed rat is one of the coolest parts.
ReplyDeleteInteresting video. I love animals :)
ReplyDeleteawesome video :D
ReplyDeleteWe have all seen a dog doing it at least once in our lives and probably tried to replicate it as kids.
ReplyDeleteI definitely do it when I mob outta the shower, kinda gets water all over the bathroom though... haha
ReplyDeleteIt's kind of cool to just sit back and watch some of the things animals can do. Interesting article Dex, keep em comin.
ReplyDeleteInteresting video there.
ReplyDeleteI cant stand it when my dog gets out of the bathtub and does this. Water everywhere.
ReplyDeletenever realized they did it it so fast... 27 hz is quite a lot
ReplyDeleteToo much science. I only watched for the cute liddle animals.
ReplyDeletehaha oh wow man that was great.
ReplyDeleteI'd would never occur to me to study the frequency at which animals shake to dry themselves.
that's a cool video of that mouse
ReplyDeleteNow I know my dog doesn't just do this to annoy me
ReplyDeleteI'd like to be able to do that!
ReplyDeleteI heat my self up in similar ways.
ReplyDeletecool video, i just thought they wanted to be dry
ReplyDeletelove your blog!
ReplyDeleteI was not aware of such complexity to a simple fur drying.
ReplyDeletenice video , i learned a lot from your blog :)
ReplyDeleteThat's damn cool!
ReplyDeleteHah, cool video and explanation, wish an actual science class was this interesting. Very neat.
ReplyDeleteawesome cute video
ReplyDeleteI wonder what it would look like when humans could do this.
ReplyDeleteI do love some oscillation frequencies before bed
ReplyDeletegreat stuff!
ReplyDeletewow thats quite a bit of work on that vid. thanks for sharing
ReplyDeleteI wish I had a pet that did this but my cats just wipe themselves on my leg to get dry, its nice to read this sort of thing.
