#tunicates — Public Fediverse posts

#Tunicates are the closest living relatives of vertebrates. Yasunori Sasakura explores a @PLOSBiology study that reveals the unique embryogenesis of Thaliacea (2 spp of #salps), tunicates that regained mobility from their sessile ancestor.

Pan-#Arctic distribution modeling reveals #ClimateChange driven poleward shifts of major gelatinous #zooplankton species https://aslopubs.onlinelibrary.wiley.com/doi/full/10.1002/lno.12568

"jellyfish and other gelatinous zooplankton could be some of the few organism groups to benefit from #climate change... the transparent #cnidarians, #ctenophores and pelagic #tunicates thrive on rising water temperatures, nutrient contamination and #overfishing."

Bizarre ancient #sea creature brings evolution mystery to the surface
A new #tunicate #fossil, a close relative of vertebrates, is half a billion years old. There is now strong evidence that #tunicates are the closest relatives to #vertebrates, but a mystery still surrounds them. How did they evolve, and what did they evolve from? A 500 million-year-old fossil is now telling us more about the #evolution of these peculiar life forms. https://arstechnica.com/science/2023/07/bizarre-ancient-sea-creature-brings-evolution-mystery-to-the-surface/

Discovery of 500-million-year-old #fossil reveals astonishing secrets of tunicate origins https://phys.org/news/2023-07-discovery-million-year-old-fossil-reveals-astonishing.html

"Ancestral #tunicates lived as stationary, filter-feeding adults and likely underwent #metamorphosis from a tadpole-like larva."

Populations of these gelatinous #zooplankton are episodic, patchy. Sometimes they bloom and form huge aggregations. Their feces, daily migrations, and sinking carcasses sequester carbon into the #DeepSea. This is especially prominent in retentive or low-export #FoodWebs.

I adore this image so much. I think it looks like a painting! Sea squirts from a marina in Suffolk. 2022 was the year I first went dock fouling. 😍

I can’t wait to go dock fouling again. This colonial sea squirt Botrylloides diegensis was pretty special.
