The Portuguese caravel (Physalia physalis) is the only organism in a heteromorphic colony, in the group of cnidarians. They live in tropical oceans, with blue or pink and purple colors. In contact with the skin, they can cause burns of up to third degree. Despite their appearance, they are not jellyfish.

Velella are stranded by the thousands at Pacific Beach, Washington in early spring. The Velella are washed into shore on warm spring tides. Their deep blue color is bleached away by the sun as they slowly decompose. Velella are a relative of the Portuguese man o’ war and are actually a community of organisms that function as one. They are also known as sea raft, by-the-wind sailors, purple sail, or little sail.
A jellyfish (Pelagia noctiluca) is in shallow water because it has been washed ashore lifeless. It has purple edges and is transparent. Jellyfish are dangerous. They can brush against you with their body or tentacles, causing itching, irritation, and stinging.
