I didn’t realize there was a condor release point out by Klamath but congrats to everyone involved! You all have no idea how much I love condors. (Or maybe you do)

You know, given how C. lupus, C. lupus familiaris, and C. latrans can all create perfectly viable hybrids, and that the proto-dogs that domestic dogs descended from much more resembled coyotes than wolves, it's not really a surprise that some yotes are experimenting with domestication.

Goddamn that lady must be fucking shredded to be able to chase down a coyote through a swamp.

"Don't let wild animals into your house, you are not going to make Dogs 2.0, you're going to get injured and the animal killed." is probably obvious enough advice that I don't need to put it in the tags as a reminder.

...I know more than four people on this site that have poisoned themselves trying out 'foraging guides' they found online, two people IRL who tried to keep raccoons at pets, and have a family member who got hospitalized for Cat Scratch Fever after grabbing a feral cat bare-handed. This is apparently, not obvious enough.

Spiders of the genus Thwaitesia are often described as mirror-ball spiders, because their bodies are lined with reflective panels that make them look like tiny disco-balls. These arachnids are also known as dewdrop spiders or sequined spiders.

The shimmering panels on the abdomen are produced by a digestive secretion known as guanine, which seeps out through the lining of the spider's gut and forms a mosaic of crystalline cells just beneath the surface of the abdomen.

The crystals shrink and expand as the muscles in the spider's abdomen contract; they often shrink when the spider is agitated, and they expand as it begins to relax.

The adaptive purpose of the shimmering effect is unclear, but researchers believe that it mimics the glistening appearance of raindrops or beads of dew, which could allow the spiders to blend in with their environment.

The reflective panels may also help to confuse predators, as this article explains:

The spider’s decorative patterning may seem like a dead give-away to predators, but for those looking to feast on this arachnid, the hunt might result in confusion and failure.

“Like a disco ball with lots of different mirrors, the reflective splotches on the spider’s abdomen probably scatter light and make it difficult for predators to see it,” says Robert Whyte, an honorary researcher in arachnology at the Queensland Museum.

There are at least 22 known species of mirror-ball spider, and their physical features can vary significantly. In some cases, the silver panels on the abdomen are accompanied by colorful, iridescent spots and scales, and the abdomen itself may have a red, orange, green, yellow, or beige appearance.

These spiders are widely distributed throughout the southern hemisphere. They can be found in the tropical and neotropical rainforests of South America, Southeast Asia, Africa, Australia, India, Sri Lanka, China, Singapore, and Madagascar.

Mirror-ball spiders are not aggressive toward humans, and there are virtually no recorded cases of humans being bitten by the spiders of this genus. They're also tiny, with most individuals measuring just 2-4mm long (roughly 1/10th of an inch), which means that their fangs are often too small to penetrate human skin.

their (live!) young gestate for. wait for it. eight to eighteen (??) YEARS. can have up to 10 at a time. good grief.

longest lifespan of any vertebrate, up to five hundred years

toxic flesh

has giant eyes but is usually blind because of a weird little crustacean that's evolved to live on and eat their eyes. this doesn't seem to bother them much.

lives in deep cold water and has the lowest swim speed and tail-beat frequency for its size across all fish species. just generally lives life in extreme slow motion
