#salps — Public Fediverse posts

The development of #salps differs from that of #ascidians in the presence of maternal cells called calymmocytes. This study of #embryogenesis in 2 salp species identifies distinct cleavage patterns & blastomere positioning, informing the study of their #evolution @PLOSBiology https://plos.io/4bscc6j

#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.

Salps are gelatinous animals that live in the open ocean, but are closely related to the "sea squirts" (tunicates) seen in tidepools. Colonial salps often form long chains, with new animals budding off from others in the chain. These chains can reach lengths of up to 15 meters (nearly 50 feet) and are one of the fastest-growing animals on the planet. ⁠

Tiny ocean migrants play a massive role in #SouthernOcean #carbonStorage

A groundbreaking study has revealed that small but mighty #zooplankton—including #copepods, #krill, and #salps—are key players in the Southern #Ocean’s ability to absorb and store #carbon.

"Deep inside the icebreaker RSV #Nuyina off the coast of East #Antarctica, as 9-metre swells and 50-knot gales rage outside, the #plankton team is busy collecting tiny creatures with the wet well: a unique sampling space below the waterline, connected to the ocean by large inlets... the wet well enables particularly fragile #animals, like #salps and #jellyfish, to be captured alive and in good condition."

Underwater starfield: A swimmer’s encounter with creatures of the open ocean https://www.whoi.edu/oceanus/feature/underwater-starfield-salps

"below me, I see something else: a host of gleaming creatures, catching the daylight, shining in relief against the black bottom. These long, translucent chains look like #ocean peapods, flecked with orange. There are more than I can count, and they are layered along the bottom in every direction... We are swimming through a bloom of #salps"

"A huge fraction of global flows of #carbon and other nutrients pass through marine #microbes. Little is known about their causes of death, however. This information determines where those nutrients will go."

"A new study led by researchers at the British Antarctic Survey (BAS) discovered #microplastics in krill (#Euphausia superba), a small shrimp-like crustacean, and salps (#Salpa thompsoni), a gelatinous #marine #invertebrate"

The results are published in the journal Royal Society Open Science

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.
