And now, as they say, for something completely different. A few weeks ago there was a news item about some slow motion film made which showed how dogs drink. It showed how a dog curves the tongue backwards to scoop up the liquid. The speed at which this happens draws up a column of liquid and by quickly closing the mouth a quantity is trapped in the mouth.
I wondered if I could film this myself with Bobby just using the TZ7 and slowing the playback down enough to see what was going on. The result is shown below. The first part of the video runs at 1/10 speed and it does a reasonable job of showing the drinking action.
Some of the original film, shown on the Discovery channel, can be found here on YouTube.
Have a great weekend observing the wildlife, and domestic life, around you.
That's a very clever piece of video. Congratulations to Bobby for staying so nice and still while you photographed him.
ReplyDeleteA great bit of video. Wasn't he thirsty enough for water?
ReplyDeleteAmazing John! Even at that speed the recoil of the tongue is still at lightening speed. It is like the curled tongue creates some sort of vacuum which sucks up a column of liquid. Thanks to Bobby for demonstrating the technique too!
ReplyDeleteThank you Mick. He was too hot and tired to rush about.
ReplyDeleteAdrian: Thanks. He occasionally gets some cool milk after a hot walk and iy showed up better than water.
ReplyDeleteBobby say you are welcome Matron. As the curled tongue tends to splash backwards now I know why he, and previous dogs, always licked their front legs after drinking.
