— 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.
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.”

Thank you dear Eurovision audience. Not only a black ocean but also booing but what did the tv station do? Fake cheering....but at least we know how it really went down. I am so not watching btw
During a dive to the Galapagos Rift Zone in 1988, scientists in Alvin saw this strange purple fish hanging out in the super-hot water gushing from hydrothermal vents at about 8,200 feet (2500 meters) depth. Pilot Ralph Hollis quickly netted the fish and brought it back to the surface for further examination. Scientists determined that it was in the genus Bythites, of which there are three Atlantic species, and promptly named it after Hollis: Bythites hollisi. They also found that it produces live young (as opposed to eggs) and is a relative of the better-known cusk eel. By 2002, more of these fish had been caught, and scientists decided that this Equatorial Eastern Pacific specimen was so different from the three Atlantic species that it warranted a new genus, Gerhardia. But a few years later, scientists wishing to avoid confusion with a beetle with the same moniker proposed another name, Thermichthys hollisi, referring to the fish’s preferred hangout, the hydrothermal vents of the Galapagos Rift Zone. So far, no other fish of this genus have been found.

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?
Photinus fireflies are probably one of North America’s most iconic and beloved beetles, and rightfully so. P. pyralis is big and bright, with a yellow-green color to its bioluminescence
I also often see these smaller Photinus with a warm orange glow. I think they could be P. scintillans, which aligns with their size, flash pattern, the yellow sclerites on males, and where I’m located. females of that species are short-winged and flightless, so I’ll try to find one to figure out the ID for sure.
reminder that fireflies eat slugs and snails as larvae! if you like seeing them in your garden, stop trying to exterminate land gastropods and leave some vegetation where the adults can sleep during the day. slugs and “weeds” = more magic glowing bugs

New research, led in part by Museum scientist Sam Cheng, shows that a male will scope out nesting sites and scare off rivals in order to improve his mating success. In this study, Cheng explains how this “probing behavior” could be a type of mate-guarding, a mating strategy in which males attempt to prevent a mate’s eggs from becoming fertilized by a rival. Ultimately, this research can help inform biodiversity and conservation efforts.

Did you know that Chiton (specifically the wandering meatloaf chiton) produce the hardest known biologically made material? Their shells are also covered in microscopic lenses that combine to almost make their body into one compound eye. Why they need to look so much, who knows?
Fast Fauna Facts #3 - Winged Argonaut (Argonauta hians)
Family: Argonaut Family (Argonautidae)
IUCN Conservation Status: Least Concern
Like the other small octopuses in the argonaut family many Winged Argonauts appear to have spiral-shaped external shells similar to those of nautiluses or ammonites, but this isn't quite the case - what appears to be an argonaut's shell is only seen in adult females, and is actually a thin-walled, calcium-based case secreted from and held by a specialised pair of arms in order to carry fertilized eggs until they hatch. Found in non-polar waters worldwide, Winged Argonauts are found mainly near the surface in the open ocean (in contrast to most octopuses, which are bottom-dwellers,) feeding on small floating invertebrates and often using their suction cups to cling to flotsam or larger animals (sometimes including other argonauts) for protection; when faced with a predator, they may attempt to position the animal they're riding on between them and the perceived threat to act as a meat shield.

What makes the dark shyshark (Haploblepharus pictus) so shy? When threatened, this critter might curl up into a ring and cover its eyes with its tail. Scientists think this defensive posture makes it harder for predators to gulp the dark shyshark down for an easy meal. Found in parts of the southeast Atlantic Ocean, this shark can grow to about 22 in (55.8 cm) long. Its diet includes crustaceans, mollusks, and fish.

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.
