I've moved this snail (egg) from the Arthropod category to the Other category for you. Snails and slugs are Mollusks. Arthropods have an exoskelaton and jointed limbs in at least one phase of their life. Think dragonfly, bee, crab, and ant.

Where do you work Misha?

We find them often at work and I've preserved many of them for use in educational programs. When you find them washed up on shore, if there are not holes in the small discs you often CAN see tiny little baby whelks inside. That one you found is HUGE!

Also - LOVE the description of "mermaid's necklace." As a mermaid, I approve!

How cool is that!

I read that it generally attached to the ocean floor and each section contains many tiny whelks...I'm so sorry that I did not look within. During storms the egg case is uprooted and floats to shore.

This is so beautiful and interesting. Is it empty, or are there whelk eggs in it?
