The Blue Ringed Octopus

Some absolutely marvelous photos of a Southen Blue-Ringed Octopus by @SammyGlennDives

Like she’s dancing!


Would love to find out what kind of protective gear the photographer had on. But it seems like the octopuses are very shy and will attack only when provoked, which is when their rings become more intense 🐙 The salivary venom1, synthesized by bacteria and not the octopus itself, doesn’t have an antidote and is only used to hunt and defend. It’s either injected via the beak, or is sprayed as a mist, paralysing the prey in either case for the final kill (presumably involving more beak.)

Here’s a little more. Love the intro. They truly are so alien and so, so beautiful 😍

  1. Always have to look it up: Poison is passive, venom is active. ↩︎

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 stretch and squeal. “Yay! I’m alive!”

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.

The last few seconds reminded me of scenes from Annihilation. Like this one:

Edit: It’s been used in Eastern Medicine for a while. Like the top YouTube comment notes, “Cordyceps is evolving to trick us into believing it is medicine.”

Way out of other birds’ leagues, eats venomous snakes, and “appears on the coats of arms of Sudan and South Africa” 🔥
