How to pronounce “cuttlefish” in English

This is not exactly to scale because I didn't have just sort of infinite room to go off here.So cuttlefish, because their internal shell has quite weak walls, they can't go much deeper than 100 or maybe 200 feet.

A lot of the things that we think of are tentacles, camouflage.There's actually a cuttlefish here hiding in the sand.It's little arms are coming down there and it has two little black eyes.

Just to give you a sense of the capacity for color change, these two photographs were taken four seconds apart.So a giant cuttlefish can completely transform it skin to that yellow in less than a second and then take it back to that reddish patterna few seconds later.

So criticize that. Then choose the right thing to explain.So the female cuttlefish lays eggs often on the underside of a ledge and then just goes off and those eggs will hatch.

You can see how the working distance is really close. Thatís a frogfish, that orange blob.This is a flamboyant cuttlefish. Maybe less interesting thanthe frogfish. It just looks like a blob, really. And these are those Plotosus, striped catfish.

This is not exactly to scale because I didn't have just sort of infinite room to go off here.So even modern nautiluses and modern cuttlefish which have an internal shell that still has gas chambers in it are limited by depth.

Cephalopods independently evolved a camera eye.So this is a giant cuttlefish, which has the same kind of eye as an octopus, a camera eye with a lens that focuses an image on a retina.You also have various sophisticated kinds of learning.

So as I said, there are roughly 500 million neurons in an octopus.The number is not really known for cuttlefish, but they may have even a slightly higher ratio of brain weight to body weight than octopuses have.The big difference between them and us is the fact that more than half of the neurons in an octopus are not where you would expect to find them, in the head,

And I won't describe all the details of the experimental design, which was very clever and subtle, but the upshot of itwas that it appears that cuttlefish do have the ability to remember not just facts like this food can be found there, but facts of the form I wasat this location an hour ago and ate or I was at this other location two hours ago and didn't eat.

What kind of memory do the cephalopods have?There's some interesting new work on this in cuttlefish, which is interesting particularly in continuities between the human and this case.So in the case of humans, there's sort of a standard distinction between forms of memory, the sort of memory of how

And these figures here are from a paper that was published in 2016 that was kind of a review paper gathering data from fisheriesand from scientific surveys from octopuses, cuttlefish, squid, ones that live close to the shoreand ones that live further out in the deep, and showing that all of them averaged together are trending up.

when you interact with them.The first ones I came across myself were not octopuses, but giant cuttlefish like this guy here.This animal was probably sort of between two and three feet long, they're not small.

She began to keep them as pets in a home aquarium and learned to scuba dive in order to meet more of themin the wild. She went on to study pygmy octopuses in Santa Barbara, cuttlefish in Australia, reef squid in Bermuda,and finally completed her PhD on, quote, "Reproduction and Early Life of the Humboldt Squid," or, quote, "Squid Sex and Babies," at Stanford.

All of our avian dinosaurs.And we still have all of our squid, and octopus, and nautilus, and cuttlefish that we talked about.And so it is a very interesting question about why some of these animals survived one of the worst days on the planet

This is not exactly to scale because I didn't have just sort of infinite room to go off here.And meanwhile, all of the other cephalopods, the octopuses, the squid, the cuttlefish, are doing all of their own things.

At some point in animal evolution, the shells were abandoned and what you were left with was a body with a kind of immense flexibility.You should think, by the way, about an octopus' arms or a cuttlefish's arms not so much as arms, but really as kind of eight or 10 enormous lips.And those enormous multi-shaped lips are extremely useful things if you can control them,

I had when I was in that place?And recently, some work that's been used to study episodic memory, or rather episodic-like memory in birds, has been also applied to cuttlefish.And I won't describe all the details of the experimental design, which was very clever and subtle, but the upshot of it

Kuo. And that is more of a Chinese deli.And they have things like the ducks and the pigs hanging in the window. uh big neon orange cuttlefish, uh intestines,whatever that all different kinds of things. But they also have this one thing that's wonderful, which is a Chinese tamalei. Now you're going

For early modern men and women, you eat your food, it sits in the stomach, gets converted into blood, blood circulates around the body, ends up in the testicles,were the "brain's stones," which is their word for testicles, and flesh of crawfish, crabs, lobsters, oysters, cuttlefish,

bottle; an inscrutable one that.They considered it a crime to throw stones into fountains and they said, "No matter you do, don't ever, ever catch a cuttlefish." Really strange stuff.But one thing they believed in makes them a lot like us, given how our world is pervaded by computing. In particular, they believed above all in the primacy of number. They believed
