Orchid plants nurture their seedlings via shared underground fungal network, study shows

The Common Spotted Orchid (Dactylorhiza fuchsii) is found all over the U.K. These orchids produce tiny seeds that can be carried anywhere by the wind, yet they often appear in clumps with small seedlings growing near mature plants. This phenomenon has puzzled ecologists since Darwin's time, with the exact reason remaining a mystery. A new study, led by researchers from the University of Sheffield in collaboration with The University of Manchester, provides the first evidence that early stage orchid seedlings germinate and thrive near to adult plants due to a kind of parental nurture using underground fungal networks. Scientists investigated the idea that fungal networks, known as mycorrhizal networks, act as a direct pathway for established orchid plants to share recently produced sugars with developing seedlings.

(Sorry to be that guy but) the leaf sheep is not actually a nudibranch, but instead part of the closely related order sacoglossa. Nudibranches are carnivorous while sacoglossa are herbivorous and feed by sucking the sap out of microscopic algae. Many sacoglossa perform a process called kleptoplasty, where they reuse chloroplasts from the algal sap they feed on and implement them into their cells. Some notable examples are the bivalve snails in the family juliidae, the eastern emerald elysia (elysia chlorotica) and obviously the sea sheep. Another slug from the order elysia (elysia rufescens) reuses defensive molecules called kahalalides as well as chloroplasts. Most sacoglossans survive primarily through heterotrophic means (ingesting and digesting) and photosynthesise when food is scarce or unavailable as a last resort. Though research has shown leaf sheep can survive long periods of time with little to no food of heterotrophic or homotrophic (photosynthetic) origin. They store their chloroplasts in cerata, which are structures often found on nudibranches and regularly used for gas exchange or- in blue glaucus’ case- for attack and defence. They also have rhinophores protruding from their face, structures also commonly found on nudibranches, which are chemosensory organs (essentially face tongues) that appear ear like on nudibranches and sacoglossans alike.

To conclude: while leaf sheep are very similar to nudibranches, they belong to the sacoglossan family (which is good because sacoglossans are just as cool) and luckily are not the only animals to photosynthesise.

(I’m researching them for a highschool project and am so obsessed haha)

So not technically a fish but I absolutely love these lil fellas

They’re Nudibranch sea slugs and they all look so pretty!!!!!

Some notable exception are the Sea Bunny (left) which is just the most adorable thing I’ve ever seen

And the Leaf Sheep (right), which is the only animal known to be capable of photosynthesis!

i am SUCH a nudibranch fan oh my god. actual underwater fae creatures. beloved little freak animals. i want to eat them like cereal

its pride month pillowspace. you know what that means.

huh? what? do you want me to post like, gay sea slugs? what?

Researchers uncover 500 million-year-old mollusk ancestor

A team of researchers including scientists from the University of Oxford have made an astonishing discovery of a new species of mollusk that

A team of researchers including scientists from the University of Oxford have made an astonishing discovery of a new species of mollusk that lived 500 million years ago. The new fossil, called Shishania aculeata, reveals that the most primitive mollusks were flat, shell-less slugs covered in a protective spiny armor. The findings have been published in the journal Science. The new species was found in exceptionally well-preserved fossils from eastern Yunnan Province in southern China dating from a geological period called the early Cambrian, approximately 514 million years ago. The specimens of Shishania are all only a few centimeters long and are covered in small spikey cones (sclerites) made of chitin, a material also found in the shells of modern crabs, insects, and some mushrooms.

This lie was pushed by the White House as well as every major Western news source...

who still haven't recanted it with anywhere near the energy they spread it with.

This lie is still being used to justify the extermination of the Palestinian people

There must be a ferocious reckoning for this.
