Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

To celebrate the beauty and wonder of the Ocean, here is a close-up series of the jellyfish Cyanea lamarckii 🪼
These images were exhibited at the @universitetsmuseet.bsky.social inviting us to appreciate the ocean’s wonders up close.
