They were washed up on the beach amongst the seaweed, felt like thick plastic, bendable, the underside being very sticky and the blue colour was coming off onto my hands. They were all different sizes, some very small, the largest was about 4cm long.

What is it made of? The tentacles are on the underside to catch small prey like plankton and I know there are right and left "handed" sails. They are found after westerlies late summer and autumn, they are annual. I would think the hard part is made of cartilage and possibly not plastic!

Velella

Velella is a hydroid but an unusual one as most are sessile (attached to a substrate) and branched like a plant. I think the solid parts are made of chitin (as in arthropod exoskeletons and fungal cell walls) which forms the float and sail,
