Photo: The strange yet adorable Umbrella Shell

1467 of 1608

This unusual mollusc has a shell that only partly covers it, acting more like a hat than any sort of armor. The photographer notes: "It's a mollusc with a small shell on top that doesn't offer much protection - just a home of a bit of algae. The body of the animal is warty and it has two tiny 'eyes' that you can see in this photo."
