Crinoids!

These are fossilized crinoids found in Western Australia by Tom Kapitany. Crinoids are animals and belong to the phylum Eichinodermata which includes starfish and sea urchins (and they all have “pentameral symmetry”). This is all well and good but these things, in their fossilized state, look like s…

An Anglerfish

What a strange, strange creature. Those bumps remind me of rivets on a submarine. But because they are anglerfish, the bumps are even more bizarre than you’d expect: Since anglerfish are deep sea creatures, it took scientists years and years to figure this stuff out. They could never find a male…

The Sand Octopus

Octopus kaurna lacks chromatophores like other octopuses. So it just burrows instead 😍🐙. It’s the only known octopus to bury itself completely like this. /misc/s/sand-octopus.mp4 The process begins with the octopus using its siphon to inject water into the sand, creating quicksand-like condition…

The Dracula Parrot

Also known as Pesquet’s parrot or the vulturine parrot. The Dracula parrot is a large, heavy bird, stretching to almost half a metre from beak to tail and weighing in at almost a kilogram. It maintains all that bulk by feeding almost exclusively on figs, which researchers suspect is why it ended…

Octopuses will do that when they leave the bottom. This is a camouflage like she’s just subdued a crab and now she’s going…

Felt like kicking myself for reading a few comments about it on Hacker News later. Not sure why I did this but promised myself I’d stick to the topics that site is good for (em…

Baby Chromatophores

I cannot get over how maddeningly cute this is. Reddit user pendragwen’s comment makes it even better: Awww! But look at how they test out their chromatophores first thing after hatching! It’s speculated that color-changing is how they communicate and show emotion. Almost like a little joyful stret…

Fungi Are Horrifying

Every person I’ve sent this to has seen it. Not sure why my own internet excursions didn’t yield this manifestly horrifying video. https://www.youtube.com/watch?v=XuKjBIBBAL8 The last few seconds reminded me of scenes from Annihilation. Like this one: Edit: It’s been used in Eastern Medicine for a…
