It isn’t World Jellyfish Day, but any day is a good day to share images of jellies!
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.

I for one will be extremely happy to peruse an illustrated guide to microscopic organisms documented through expansion microscopy. www.sciencedaily.com/releases/202...

I suppose it is natural to have the comparison point by “human” in discussing the earliest divergence with metazoans. Consider the source! That aside, another marker post in the Porifera-or-Ctenophora first (divergence) is fun to see. www.science.org/doi/10.1126/...

Record your sightings! ⭐📋

Citizen science is a huge part of marine conservation and one of the most fun ways of helping our seabeds. Whether you’re out snorkelling or rock pooling, you can record your findings by submitting them to the iNaturalist app.

This is the best write up of the recent observation of a species of stalked medusa that hadn’t been seen in 50 years. www.britishwildlife.com/lost-and-fou... Some of the press is reporting this with the narrative “rediscovery of an extinct species”, which is not the case. It is positive news though.

Sponges are called ecosystem engineers because they provide habitat for MANY types of OTHER animals! Including these "creeping" or bottom comb jellies-note the two white strings coming off them? feeding tentacles! #spongeThursday #Okeanos 2015 Bank 9 North

Last weekend I got to see NZ velvet worms in their native forest habitat. These animals are so bizarre, taxonomists gave them their very own Phylum, next to tardigrades - that's insane!

This Ooperipatellus sp. is an egg-laying genus, but there's another here that gives live birth!

Mind. Blown. 🧪

I’m so excited to have finally found one of these copepods! This is from the family Corycaeidae - I’ll be IDing it to genus (hopefully) later on, but I wanted to share it straight away because I’m so thrilled! LOOK AT THE EYES!! Aren’t they super cool?! 🦑

I got up close with a Portuguese man-o-war and my god these animals are shockingly beautiful.

Excited to share our study on sailing siphonophores, AKA bluebottles or man-o'-war! 🌊 we received hundreds of samples from scientists around the world, part of a huge effort to sequence genomes and test for multiple species 🧬 out today in @currentbiology.bsky.social doi.org/10.1016/j.cu... 🦑🧪📌
