They actually saw the crab enter the hole, so we decided it was time to utilize the "Fripp Island Ghost Crab Trap" again.
As we were removing the cage, at the upper right corner about 9 inches below the surface of the sand, 4 hatchlings fell through the wall of the cage!
Were they caught in the ghost crab tunnel? No way to know for sure, but now that they were out, we needed to release them as soon as possible.
