Shot of sand on a beach with some rocks in the distance and a closeup of a jeelyfish called Vellella Vellella on Calvert Island

Vellella vellella

Have you seen these jellyfish washing up on BC beaches this summer? We saw this one on Calvert Island. They’re called By-the-wind-sailor, sea raft, purple sail, or little sail – or by their scientific name Velella velella. They eat plankton and are eaten by nudibranchs. It looks like just one individual but it’s actually a whole colony of all-male OR all-female polyps! Some polyps are in charge of reproduction while others are for protection.
