While diving Secret Bay I noticed a tiny ball that was bobbing furiously up and down from the sand. Its shape was too perfect a sphere to be a piece of coral so I swam nearer. Upon closer inspection, I discovered it to be an inflated puffer fish that was half buried in the sand. This behavior definitely isn’t normal for puffer fish as they only inflate and swim away when they’re threatened. Frankly it looked like it was taking a crap!
I then noticed it trying to push itself out of the substrate, with extreme difficulty! Something was holding it down. Then it dawned on me: it was fighting for its life! Something was dragging it down into the sand for dinner!
Can you guess what we did?
