8) Lets talk about Lemmings
0:06
When you hear the word “lemmings” you might think of two things:
0:08
This video game and some sort of small creature that suicidally leap off cliffs when its population
0:12
grows too large.
0:13
In case you didn’t know lemmings are real and adorable and not suicidal.
0:17
The origin of this myth is a bit unclear but the video game lemmings may have done a lot
0:20
more to convince a younger generation that lemmings are willfully suicidal – and extremely
0:23
frustrating to micromanage thus deserving of mass extermination.
0:25
7) Daddly Longlegs
0:27
These wispy-looking things have earned the reputation as the most poisonous of any spider.
0:31
But they’re also pretty common so, you might wonder why more people don’t die from daddy
0:33
longlegs bites every year.
0:35
Like a good conspiracy theory, this myth, covers its own tracks by also saying that
0:38
their fangs are too small to penetrate human skin.
0:40
You could score one for team human except that this misconception is a triple whammy
0:43
of wrongness:
0:44
1) Daddy Longlegs don’t have fangs because
0:46
2) They don’t produce venom because
0:47
3) They aren’t even spiders
0:49
6) Ostriches
0:51
Let’s review the properties of these flightless birds, shall we?
0:53
They’re up to nine feet tall, up to 340 pounds, aggressive, with sharp beaks and long
0:57
claws.
0:58
Essentially an ostrich is the closest thing to a living raptor you’re ever going to
1:00
see.
1:01
(That is our genetic engineering technology gets better – common dinopocapolipse!).
1:04
Anyway, keeping these facts in mind, if you decide to threaten an ostrich do you really
1:08
think it’s going to stick it’s head in the sand and wait to die?
1:10
No, of course not, if you’re lucky it will run away at 40 miles an hour and if you’re
1:14
not, it’s fatality time for you.
1:16
Ostriches have no reason to hide and especially not in the stupidest way ever.
1:20
If they did they would have survived about as long and another species of flightless
1:23
bird.
1:24
While we’re talking about flightless birds,
1:25
5) Baby Birds
1:26
A mother bird won’t abandon her baby because you’ve touched it any more than a human
1:29
mother would abandon her baby if a bird touched it.
1:32
If you find a baby bird and can easily reach the nest, it’s perfectly fine to put it
1:35
back.
1:36
4) Goldfish Memory
1:37
Goldfish do have memories longer than three seconds or seven seconds or whatever other
1:41
made up number always accompanies this fact.
1:43
They can actually be trained and will remember what they learned for months.
1:45
Which is more than can be said for many humans.
1:47
On an unrelated note, Goldfish are also delicious.
1:49
3) Dog Vision
1:51
Poor dogs, forever living in their sad, monochrome worlds.
1:54
Except, they don’t.
1:55
Dogs do see color, but not quite like us.
1:57
Most humans see three primary colors, red blue and green, but dogs are limited to two:
2:01
they can see blues, but the rest of the color spectrum they can’t tell apart.
2:05
Which they don’t mind, until you buy them a red toy and throw it into the green grass
2:08
and act like they’re stupid for not finding it.
2:10
It’s easy for you to see because your ancestors spent several million years foraging for red
2:13
objects on a green background and so got quite good at it – unless they didn’t which
2:16
in that case they died – but canine eyes are not monkey eyes and to your dog, if it
2:20
isn’t blue it’s all the same color.
2:21
So next time you’re at the pet store, get rover a blue toy.
2:24
And, while we’re talking about vision lets talk about
2:26
2) Bats
2:27
Which, if you’ve ever looked at one, it should be immediately obvious they’re not
2:29
blind because they look right back and you – with their eyes – that they use to see
2:33
things.
2:34
But they do one better by having an additional sense called echolocation that allows them
2:37
to navigate the world in complete darkness, something you can’t do.
2:40
So from the bat’s perspective you’re the blind one.
2:43
1) You Can Boil a Frog to Death if you do it very slowly
2:46
This one is true… sort of.
2:48
Friedrich Goltz, demonstrated that a frog will remain blithely in a pot of water brought
2:51
to boil if the temperature is raised slowly enough.
2:54
However, the rather salient fact that is often left out of the retelling is that Goltz cut
2:57
out the frogs’ brains before placing them in the pot.
3:00
Which rather puts them at a disadvantage.
3:03
Goltz also showed that if you don’t lobotomize the frog first then – surprise – it jumps
3:06
out of the pot.
3:07
It seems likely – but please don’t try this at home – that removing the brain of
3:10
any animal would rather hinder their instinct of self preservation.
3:13
And also make them more gullible about common misconceptions.
