Which Animal Doesn't Have A Shadow? | QI 

I really appreciate it when people demonstrate they know something interesting on this show.

"the moon is kind of my thing" - one of the great lines from the show

Another potential use I've seen for this technology is Semi/large trucks can 'display' whats in front of them on their massive rear door, essentially allowing cars to see through them instead of having a large blind spot directly in front of them

"I forgot you were a moon chap" Stephen's use of English always brings a smile to my face

According to Douglas Adams, making something invisible is perfectly possible, but involves so much tedious mucking about that 99 times out of 100 it is better to do away with the thing altogether.

Ooh, that was a good clip. I don’t remember that episode, although I thought I had seen them all. I love that a squid can hide its own shadow and was quite impressed with Chris Addison’s knowledge of Jim Lovell!

My Dad was on a carrier during the Korean war, and he said the luminescent trail behind the fleet was a beautiful thing to see.

I think Lou Sanders question “isn’t nature interesting?” is applicable that squid lol. They need to to get Addison back, he was absolutely brilliant on every episode he’s been on. That Jim Lovell fact was superb.

I feel motivated to pedantically point out that the Hawaiian bobtail squid is not so much concerned with concealing its shadow as it is with concerning its silhouette. The point of the bioluminescent symbiosis is to disguise it from predators lurking below it, who would see it pass through the moonlight otherwise.

"The moon - that's my thing" - does that make Chris a lunatic?

Wow, even "ANIMAL" in the thumbnail doesn't have a drop shadow

The story of Jim Lovell finding his ship by following the churned-up bio-luminescent algae was included in the film _Apollo 13_ [1995].

Another item of trivia about Jim Lovell: he is the only man to have been to the moon twice and not land on it (he orbited the moon in Apollo 8, and then went back with Apollo 13, which famously didn’t land).

I just saw Stephen Fry on the Sandman series. I didn’t know he was in it and squealed with delight when he showed. It was wonderful casting for the role.

Ah yes, the moon chap. But I'd be willing to bet that if he were asked how many moons the Earth has, he'd get the Klaxon. QI seems to change its mind on that question just about every series !!

That story about Jim Lovell using his ship's wake to find his way back is mentioned in the Apollo 13 movie,

I spent 20 years in the Navy, my first 6 on active ships. The luminescent sea is that rare of an occurrence. It happened quite often off the coast of San Diego.

Jack's final expression - LOL! 😀

Anything that moves around in complete darkness where there is no light to create a shadow.

Would never see this type of discussion on American television.

BTA--back to audience--is part of theater arts training. It makes you "invisible" while other actors are speaking.

“The moon, that’s my thing” killed me

One of the issues with a human being truly invisible (as in the film Hollow Man etc) is that light passes through you and that's what makes you invisible to the observer. Unfortunately, light passes through your retina, so you're blind. The game Quake 2 had a powerup (ironically called the Ring of Shadows) that gave you brief invisibility, however it dealt with the blindness problem quite neatly. I was in a multiplayer game for the first time, and could hear this odd whispering and started hunting around for its source. It was the audio effect of another player that was next to me wearing the ring. I turned and he was invisible apart from his eyeballs, these two bloodshot orbs floating in the air next to me. I nearly shat myself.

I see what you did with the thumbnail. Very clever QI RU-vid team.

Wondered about the thumbnail before remembering the Elves are never not deliberate!

Amazing fact about the shadow!

If you ever wondered who owns The Moon, apparently is it's this fellow, Chris. It's his thing.

They could have stumped Chris by asking him one of the following questions: 1. Which moon is your thing? (Followup: Which of Earth's moons is your thing?) 2. How many moons does Earth have?

The invisible Aston Martin in 'Die Another Day'. Ian Fleming hasn't stopped turning in his grave.

I was a bit annoyed they didn't show the animal doing it's super camouflage thing. But then yeah, I guess that makes sense, lol

"The moon, that's my thing." Oh really Chris. How many moons does the Earth have then Chris, huh?

"Q" already perfected it, as one of James Bonds cars had an invisiblity button. It was the film that ended up in Iceland, the only problem was, it left tyre tracks in the snow.!

i like how stephen is aware of how cloaking technology in star trek is very much tied to the romulans even the klingons got it from them

Knowing how much I like British TV my son (who's addicted to British TV game/quiz shows) introduced me to QI last year and I'm glad he did because it's fantastic.

I remember years and years ago reading about a "cloak of invisibility". It was being developed by our defense department. They watched insects to learn how to make one. Unfortunately, it casts a shadow, a problem they could not solve. Perhaps they should have consulted a Klingon. 🙂

"I will turn myself into a shining beacon so that predators cannot spot me by my shadow!"

I thought it was gonna be a very clear jellyfish lol, cool squid!

🎶Meeee... and my shaaa.... 🎶 Oh it's gone. I'm all alone now. * sniffles *

I can’t help but keep looking at how the shadow is making Chris Addison’s face look 2D

Anyone who has seen Apollo 13 should know that Lovell story. It’s featured in a TV interview played during a news broadcast.

Liked the matter of fact way Stephen says the Romulans currently have cloaking technology 😂

Chris Addison is so adorable

Anybody who has seen the movie "Apollo 13", would know about the aircraft carrier incident. It's mentioned in a TV interview in the film.

I seem to recall chameleons don't actually camouflage themselves to their immediate environment

How smart is the squid if it knows it makes a shadow. And how smart to figure out how to get rid of it.

Wow, nature is the Best.

3:22 "In complete blackness, I think there was no moon as it happened that particular night" Why did he not simply use the other moon?

That's really clever and strategic to shine like a giant light bulb every time you want to go incognito.

3:09 "it's a lot of bother to go to, though, isn't it, to be honest ?" Perhaps not, when you consider that the bother the octopus has gone to will save its LIFE x number of times.

Why is it when you are invisible that a shadow still appears? Doesn't being invisible means there is nothing to make a shadow as light passes through you.

I see Fiddler's Green got up to some interesting jobs down here on earth

The animals that don't leave a shadow would be those transparent fish deep in the ocean.

Its so wonderfully witty isnt it!?

In "THHGTTG" there is the S.E.P. Ford Prefect explained it very well.

"The moon, that's my thing." KLAXON!!! - The Moons.

Two other considerations for shadowless animals might be a bat and or a jellyfish. No?

I always wonder if a glow worm has one. 🤔

I want to know when there will be another series.

Starts at 2:52.

My guess was either a tardigrade or a skeleton shrimp. Two animals with completely clear bodies and incredibly small.

Er, you, can produce this effect by connecting a camera to a projector and putting any form of screen between them!!!

just sew together a jacket out of those things you can't see.

The occasion to ask "how many moons?" was lost T_T

Hey! I've seen the woman at the end in a Time Team episode!

A pilot has a camera under his plane so that he can see below ? Mind blowing!

The firefly or the jellyfish

Jim Lovell the luckiest unlucky person ever.

Stephen Fry and Jeremy Paxman should be joint PM's , in perpetuity .

My wife has an invisibility machine. It's called a mobility scooter.

It's amazing what God can create.

I mean, the animals in question are only luminous at certain times. But a major aspect is it on nights with no moon. So, not a complete coincidence.

2:11

Jim Lovell said he would have cast Kevin Costner instead of Tom Hanks on 'Apollo 13' because there is a notable resemblance.

I used to love watching QI when it was entertaining.

I thought they were going to say the Vampire bat. Cephalopods are amazing creatures! Doubly so for being molluscs.

A segment on invisibility and Rich Hall decides to be silent. Too bad, I've not seen him in many decades and he's very witty. Love Stephen Fry, too. He's one of my favorites from the Black Adder.

Now THAT is how you showcase your knowledge of a specialist subject on QI WITHOUT looking like a smug, condescending prick (Rory McGrath, I'm a-lookin' at YOU!) Chris Addison is ALWAYS a class act on this show.

There's another one, the fringed gecko... There is also a spider with fringes.

It's a shame Sniglets weren't helpful here for Rich Hall.

I'm going to say the phoenix, since all of its body is a light source, and also doesn't exist.

How is this not just a projector?

Jelly fish

Fireflies ! or any animal that produces light

Bond had an invisible car in Die another day

A much better show when there are knowledgeable people on it. Too often these days it just comedy, no information.

The thing that’s cool about this host is he’s ridiculously intelligent, but if someone chimes in with added knowledge he doesn’t get all insecure. I’m in America and if you know the answer to something at a bar you’ll get in a fight if the guy hears you correct him. Props Britain. Props.

That video is atleast 10 years old

Most any and all animal that lives in a cave has no shadow.

Moonchap.

Given that footage looks like it's from the early to mid 90s I'm going to say this technology hasn't advanced much.

I was waiting for someone to ask him how many moons the Earth had after he said the moon was his thing

The first animal which came to my mind was the firefly. Not that for off

Earthworm

um, it's just two cameras, which we've. had for a long time....

My guess was a jellyfish

I read the title and my first thought was - Unicorn!🦄

Well that animal still has a shadow then in reality. It is just able to hide it. I was guessing on some creature being so "clear" light when throu it completely ..no idea what it should have been, kinda why i clicked vidoe to see if i was right. I mean i can hide my shadow aswell .... just making sure light aint hitting me ... or make it sure my shadow hits bigger shadows or darkness. So i have no shadow aswell ? :P

I'm a BIT ashamed that it took me THIS long to realize that there is a flaw in that plan.. IF you are an octopus.. and you can change texture of your skin, crawl in any shape you like, etc, to camouflage.. and then.. it learns to hide it's shadow too???.. Ehm.. Doesn't this mean we have an octopus f.ex. trying to look like a rock.. but will be the only rock around without a shadow? Kind of like when they said that they thought a octopus running on the ocean floor was trying to look like a coco-nut.. but.. coco-nuts are famously ~land based~ furry marsupials.. not water.. and also.. famously they do float (If I remember correctly from a previous episode this means they are witches).. and.. lack legs and therefore never run (they take ubers).... So.. "this thing that you probably never seen, and if you saw it it would be floating silently on the surface?.. here is one running on the oceanfloor."..

The Jim Lovell story also happened to George Bush in WW2

I feel glowing brightly would kind of negate the advantage of casting no shadow...
