A Team Of Researchers Including Scientists From The University Of Oxford Have Made An Astonishing Discovery

its pride month pillowspace. you know what that means.

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

@confidently-regretful

(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

Snails in the genus Julia have a bivalved shell, like a clam!

Even though they have a clam like shell, with 2 sections, they are in fact snails (class Gastropoda). They are marine snails, found throughout the Ino-Pacific. There are 6 species which are various shades of green. Julia are tiny, only reaching a length of up to 6 mm long. They feed on algae, and incorporate the chloroplasts from the algae into their bodies. Some of the chloroplasts remain photosynthetic, and the snails are able to feed on the products of this photosynthesis. This process is called kleptoplasty.

Wild Elephants Invent Names For One Another in Surprise Sign of Abstract Thinking

Elephants call out to each other using individual names that they invent for their fellow pachyderms, a study said on Monday.

Elephants call out to each other using individual names that they invent for their fellow pachyderms, a study said on Monday. While dolphins and parrots have been observed addressing each other by mimicking the sound of others from their species, elephants are the first non-human animals known to use names that do not involve imitation, the researchers suggested. For the new study, a team of international researchers used an artificial intelligence algorithm to analyse the calls of two wild herds of African savannah elephants in Kenya. The research "not only shows that elephants use specific vocalisations for each individual, but that they recognise and react to a call addressed to them while ignoring those addressed to others," lead study author Michael Pardo said. "This indicates that elephants can determine whether a call was intended for them just by hearing the call, even when out of its original context," the behavioural ecologist at Colorado State University said in a statement.

Uncharismatic Fact of the Day

It's not every day you see a fish walking on land! However, when the streams and ponds of the airbreathing catfish dry up, this species will readily wriggle across the jungle floor in search of a new home. Thanks to a special organ called a labyrinth organ, they are able to breathe air and can remain outside of water for several hours provided they stay moist.
