Here is a juvenile Chrysaora colorata, one of my favourite species of scyphomedusa, native to the Californian coast.

Happy #worldjellyfishday, everyone 🪼🪼🪼!
Jellyfish (and their blooms) are a fundamental part of marine ecosystems, significantly contributing to carbon transport and storage. An ocean without jellyfish would not be a healthy ocean.

A new paper just dropped a little while ago describing a new family for a common species of benthic ctenophore (comb jellies), Coeloplana meteoris, now known as Benthoplana meteoris. www.jse.ac.cn/EN/10.1111/j...

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

🌊 Happy World Ocean Day! 🌊
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.

Corymorpha nutans, it is also the first jelly that appears with the stomach full. They bud from a polyp like the one in this video from @alexandrejan.bsky.social. Crazy hydrozoans!
