INVERTEBRATE OF THE YEAR CONTEST! I love the immortal jelly pick. In my book about Spineless Superpowers (The Oceans Menagerie @vikingbooks.bsky.social and on Amazon), I chose Jellyfish Bioluminescence; Green fluorescent Protein won the 2008 Nobel prize for its immense value as a live cell tracker.

Scientists monitor the loss of vital eelgrass plants in Salish Sea
The marine vegetation helps mitigate climate change impacts and serves as vital habitat. But a study finds the species is at risk in the San Juans.

Here is the story in our words of the experiments Melanie and Alyssa @rhizalyssa.bsky.social and Grace ran to discover the Vibrio bacterium causing sea star wasting. And Amy Chan's work to get it in culture, so we essentially fulfilled Koch's postulates... theconversation.com/the-bacteria...
