When I was in Thailand, I wrote about the day I found a bunch of clams on the beach. Then I posted some videos of them burrowing into the sand. Here now are videos of the two that I took back to the hostel, climbing around, burrowing, and otherwise doing amusing things. I’m not the only one to find this fascinating, am I?

(Yeah, I know, it’s slow going. But check out how the sea snail flips itself over and burrows away, whereas the clam goes in tip first and squeezes its shell.)

It just glides so smoothly. But out of water, it finds it’s no match for gravity:

Part claw, part… lotus? You decide:

Based on the previous video, now can you find the part of the clam that is sticking out?

And then the grand finale! The clam is so happy it burrows a little, then thrusts itself out of the sand. Meanwhile, the sea snail decides to come out to play too.
