Found these by the thousands on the beach at Cape Kiwanda. Anyone know what they are and why they end up on the beach?

The big ones are blue and the small are clear.

Velella is a cosmopolitan genus of free-floating hydrozoans that live on the surface of the open ocean. There is only one known species, Velella velella, in the genus. Velella velella is commonly known by the names sea raft, by-the-wind sailor, purple sail, little sail, or simply Velella.

Awesome! Thanks!
