What are the blue blobs on the beach in Florida?

Each blob is really multiple individuals. These are marine hydrozoans, a group of animals closely related to jellyfishes. Interestingly, what might look like a single animal is actually a colony of multiple individuals working together. This is similar to the Portuguese man o' war, which is also a colonial hydrozoan.
