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

How did life get multicellular? Five simple organisms could have the answer
Single-celled species that often stick together in colonies have researchers rethinking the origin of animals.
