Setting foot on Danco Island, it wasn't long until encountering this eggshell. A sad reminder of a once feeble life. Much of cruising through Antarctica revolves around landing on small islands in the Antarctic Peninsula, as was the case with this island.
I'm just going to assume this is a penguin eggshell. Probably the little guy never quite hatched and was instead sadly eaten by another bird. Such is the circle of life.
