According to a Facebook post from the Point Reyes National Seashore, Velella velella are flat, oval-shaped hydroid polyps and are cousins of jellyfish.
They live in the open ocean but are often seen washed up on beaches, including the Point Reyes National Seashore, during the spring and early summer months when strong winds push them ashore.

FOX 11 reports that while they pose little threat to humans, it’s advised to be careful when touching your face or rubbing your eyes if you pick one up because they can cause a slight irritation to your skin.
