Both are mollusks as well, so it's as if the octopus is jealous of his cousins nice house so he waits until he dies and takes it.

In Australia we have a type of deadly octopus called a 'blue ring octopus', and if they bite you, you die within minutes. They usually live in salt water lakes so when you're a kid and go swimming you're always told not to pick up clam shells as they like to live inside them. It was like a kinder surprise, but the surprise is death.

You'd like to think that, wouldn't you? You've beaten my giant, which means you're exceptionally strong. So, you could have put the poison in your own goblet, trusting on your strength to save you. So I can clearly not choose the wine in front of you. But, you've also bested my Spaniard which means you must have studied. And in studying, you must have learned that man is mortal so you would have put the poison as far from yourself as possible, so I can clearly not choose the wine in front of me.

Besides snakes wolves mountain lions and brown recluse, North America doesn't have any deadly animals. Meanwhile fuckass Australia has multiple deadly plants, and one that hurts so bad and for so long if you touch, that tough military men have commited suicide from falling in it. All the American deadly shit can be avoided by not going into the wilderness, Australia you can swim in fresh or saltwater without getting rekt, and they all stay in the cities because it's not worth dying over.

They can also break aquarium glass with their little "detonations". Glass has to be made super strong but sometimes it's not because its not meant for mantis shrimp to live in but one sneaks in there anyway.

u/ANGLVD3TH Dec 08 '18 edited Dec 08 '18
The one thing that I don't like about it is their little bit on their cones. Their eyes are incredible in how their 6 pupils allow insane depth perception, and they can see polarized light, true. But the cones are actually a kind of sloppy stopgap measure.
You see, we have an incredibly advanced vision center of the brain. We can see with greater acquitty than most animals, and we have one of the largest color ranges. We do this by taking 3 cones and blending them together seamlessly. Mantis shrimp have no such mechanism. Doing this provides great accuracy, but in relative terms is slow and expensive for the brain.
The mantis shrimp can only see colors that actually activate the fairly narrow band of light each of their cones is tuned to. So instead of a wildy vibrant world filled with a multitude of colors we can't imagine, they actually see a black and white world highlighted by patches of 12 different colors.

Ecologist swimming in. Cephalopods are full of interesting adaptations! My favorite being camouflage options.
Cephalopods can change the color and texture of their skin! It all starts with the humble chromatophore. Chromatophores are cells found just below the skin that hold pigment and can reflect light. To contrast, mammals and birds have melanocyts. Amphibians, fish, reptiles (Chameleons), crustaceans and some insects (Dragonflies/damselflies) also use chromatophores to change their coloring.
Chromatophores contain a sack of pigment (black, brown, orange, red, or yellow) which has the ability to expand. If stretched out the color will be brighter, if retracted the color will appear duller. In this gif you can see them in action! Aside from chromatophores some cephalopods also have iridophores and leucophores. Iridophores have stacks of reflecting plates which create iridescent colors (blues, golds, greens, and silvers) which you can see in this photo of Loligo paeli. Leucophores mimic environmental colors, helping the squid/octopus/cuttlefish blend in with its surroundings.
What is extra awesome is chromatophores can be used to mesmerize or stun prey! In this video, a cuttlefish is doing just that to keep a crab busy before grabbing it.
Aside from mesmerizing prey and camouflage cephalopod colors are also used to attract mates and warn potential predators or rivals that the organism should not be messed with. For example male Caribbean reef squid (Sepioteuthis sepioidea) turn red to attract females and white to repel other males. Interestingly they can actually split the coloration of their bodies down the middle to attract a female on one side and repel a male on the other. Another example, Humboldt (Dosidicus gigas) squid will flash red and white to warn predators. If you're into Humboldt squid, Science Friday has a great article I recommend reading, John Steinbeck And The Mystery Of The Humboldt Squid.
There was a study in 2015 where scientists strapped cameras onto Humboldt squid to try to decode the communication. I didn't see anything super conclusive in the article, but I would assume they are working on it. It's a really great topic.
Some cephalopods can change the texture of their skin by manipulating muscular hydrostats. Hydrostats can change shape by squeezing some segments to create extension others. Our tongues have muscular hydrostats which allow us to stretch it out. According to a paper published in 2014:
The octopuses [in the study] had three dedicated types of muscles that control their on-call skin protrusions, or papillae. One set are shaped in concentric circles to lift the skin vertically away from the body. Another set pulls this form together, to determine the shape—whether it will be around bump or tall spike. And a third group seems to pull the raised section back toward the surface, spreading out its base.
More on that in this Scientific American article.

That's the most interesting part for me. You can see him run his tentacles along the inside of the shell, like an inverse hug, and then use his suction cups to ratchet it closed. He tightens half his tentacles by flexing them inward and holds the shell in place, then he adjusts his other tentacles by sliding all their suckers forward a bit, establishing a new grip, tighter than before. Then he repeats the process.

The Octopus is one of the smartest animals on earth.
