Conservation good news: Giant anteaters are returning to south Brazil thanks to rewilding efforts

— Recent giant anteater sightings in Rio Grande do Sul state indicate the species has returned to southern Brazil, where it had been considered extinct for more than a century.

— Experts concluded that the giant anteater ventured across the border from the Iberá Park in northeastern Argentina where a rewilding project has released around 110 individuals back into the habitat.

— The sightings emphasize the importance of rewilding projects, both to restore animal populations in specific regions and help ecosystems farther afield.

— Organizations across Brazil are working to protect and maintain current giant anteater populations, including rallying for safer highways to prevent wildlife-vehicle collisions that cause local extinctions.

Playing back hours of footage from a camera trap set in Espinilho State Park in the south of Brazil in August 2023, Fábio Mazim and his team banked on possible sightings of the maned wolf or the Pantanal deer and had their fingers crossed for a glimpse of a Pampas cat (Leopardus pajeros), one of the most threatened felines in the world.

What they didn’t expect to see was an animal long presumed extinct in the region. To their surprise, the unmistakable long snout and bushy tail of a giant anteater ambled into shot.

"We shouted and cried when we saw it,” the ecologist from the nonprofit Pró-Carnívoros Institute told Mongabay. “It took a few days to grasp the importance of this record. A sighting of a giant anteater was never, ever expected.”

Last seen alive in the southwest of the Rio Grande do Sul state in 1890, the giant anteater (Myrmecophaga tridactyla) has since been spotted 11 times since August 2023, although the scientists are unsure whether it’s the same one or different individuals. However, the sightings confirm one clear fact: The giant anteater is back.

It's a huge win for the environment. Giant anteaters play an important role in their ecosystems, helping to control insect numbers, create watering holes through digging and are prey for big cats such as jaguars and pumas.

The habitat of the giant anteater stretches from Central America toward the south cone of Latin America.

Its conservation status is “vulnerable,” although it is considered extinct in several countries, including El Salvador, Guatemala and Uruguay, as well as specific regions such as the states of Rio de Janeiro, Espirito Santo, Santa Catarina and (until now) Rio Grande do Sul in Brazil and the Cordoba and Entre Rios regions in Argentina.

‍In the last six months, the giant anteater was spotted on camera 11 times in the Espinilho State Park in the state of Rio Grande do Sul in Brazil. It was the first time in 130 years that the species has been seen alive there.

Yet not only is it a triumph for conservationists to see these animals returning to Brazilian biomes, it’s also a surprising mark of success for a rewilding program about 150 kilometers (93 miles) away in neighboring Argentina.

‍Rewilding Argentina’s biomes

‍Iberá National Park in Corrientes province in northeastern Argentina is a 758,000-hectare (1.9 million-acre) expanse of protected land comprising a part of the Iberá wetlands with its swaths of grasslands, marshes, lagoons and forests. The region was once home to just a handful of giant anteaters after habitat loss, hunting and vehicle collisions decimated the population.

Since 2007, the NGO Rewilding Argentina, an offspring of the nonprofit Tompkins Conservation, has been reintroducing the species back to the area, most individuals being orphaned pups rescued from vehicle collisions or poaching.

So far, they have released 110 giant anteaters back into the wild. Nowadays, several generations inhabit the park, transforming it from “a place of massive defaunation to abundance,” Sebastián Di Martino, director of conservation for Rewilding Argentina, was quoted as saying in an official statement.

The project has been so successful that the giant anteaters appear to be venturing farther afield and moving to new territories beyond national borders, such as Espinilho State Park in Brazil’s Rio Grande do Sul region...

Experts now hope that a giant anteater population can reestablish itself naturally in Espinilho State Park without the need for human intervention.

“The giant anteater returning to Rio Grande do Sul shows the success of the work done in Argentina and how it’s viable, possible and important to do rewilding and fauna reintroduction projects,” Mazim said. “It is also an indication that the management of conservation units and also the agricultural areas of the ecosystems are working,” he added. “Because if large mammals are coming from one region and settling in another, it is because there is a support capacity for them. It is an indication of the health of the environment.”

Evil biology facts that fill me with Fear :)

hey, I heard y’all like evil biology facts like knowledge about horse blood types.

well! today I was researching alternative biochemistries extraterrestrial life could use and. man. I think Earth life is fucked up enough for me thanks

biological dark matter. WHAT DO YOU MEAN MY BLOOD HAS DNA IN IT FROM NO KNOWN SOURCE. YOU CAN’T JUST SAY THAT COME BACK HERE

One specific cave that has been sealed for 5.5 million years and has developed an ecosystem completely dependent on chemosynthetic bacteria.

Was anybody going to tell me that bacteria have decided iron is yummy and are eating the Titanic, or was I supposed to just read that myself

Terrible Berry (yes, that’s what the genus name means). This whole thing is so fucked up. These scientists were testing whether radiation could be used to kill pathogens in food, so they dosed a tin of meat with enough radiation to kill any known living organism (as one does) but guess what, it still fucking spoiled because of THIS BASTARD FUCKER.

(seriously, why is it like this? WHY has a bacterium evolved to chill in radioactive waste like it’s a soothing Jacuzzi tub? What does it know that we don’t know?)

(ANSWERS. I WANT ANSWERS, YOU CHERNOBYL ASS BITCH.)

Cursed worm, which has no mouth or digestive system and depends entirely on five (5) different species of bacteria, which consume hydrogen sulfide, hydrogen monoxide, and carbon monoxide, for food. How do you, a worm, even...figure out how to do...all that?

Bone worms. At least they like their bones already dead. I still could have gone without knowing this was a thing.

“Oh, parasitic plant, that sounds c—WHAT THE FUCK IS THAT THING”

I am like half convinced this is made up. Seriously, bacteria grow their own electrical wires and we just let them?

Six sets of Sacoglossa stickers! These are sea slugs, also named solar-powered sea slugs are able to photosynthesise! The mascot of this superorder is the sea bunny with their vibrant green bodies and pink rosy cheeks

Each pack will have a little information card and fun facts about these cuties.

Have put a lot of time and passion into these and hope you all like them as much as I do :)

I put it to you that Scaphiophryne marmorata is peak frog.

Why?

Well first, it's pretty round, which is key.

Now get a load of those fingers.

Big, expanded discs at the end, ideal for climbing.

But what's happening back there with those toes? No discs there. Those are good for walking and hopping around on the ground.

Now, let's gently turn them over

First, excellent tum, 17 out of 10, no notes.

But what's that at the base of the foot? Those big projections? Yep, those are spades. This climbing, hopping frog is an excellent digger!

I like to think of these Scaphiophryne as all-terrain frogs. They're basically good at everything. They defy our categorical labels of 'arboreal', 'terrestrial', or 'fossorial', and say 'por qué no los tres?'—but in Malagasy, so 'nahoana no tsy izy telo?'

(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
