G'day,

Walking on a beach in northern Tasmania (Weymouth) at very low tide I came across this pattern in the sand.

What made those squiggles?

I tried to find the critter responsible but no success. Not enough time, unfortunately.

it's going to be very difficult to say much with just the tracks. one obvious question is how big they are - there is no scale in the short.
