NARRATOR: Animals
 have amazing brains.
They're much smarter
 than we usually think.
Study up 'cause Awesome
 Eight is presenting eight
incredibly clever creatures.
Number eight.
Octopuses are
 curious creatures.
They can open jar
 lids, solve puzzles,
and some have even found
 escape routes from their
aquarium enclosures.
They can wriggle their
 boneless bodies through
passages as
 small as a quarter.
Octopuses are fast learners,
 and can even recognize
individual human faces.
Number seven.
One of the closest
 relatives to humans,
chimpanzees have been seen
 chewing sticks to create tools
designed to soak up
 water for drinking.
They pass on tricks to
 other family members,
which is a type of social
 learning reserved for the
smartest of animals.
Chimps are great teachers.
Number six.
Despite their tiny size,
 army ants construct
 amazing bridges.
Researchers have discovered
 that no single ant calls the
shots in the bridge-building.
They make calculated
 decisions as a colony.
Number five.
Besides looking super-creepy,
ravens are actually quite smart.
They can use their beaks
 to rip things open
to find food and shelter.
Four.
African Gray Parrots are
 excellent at mimicking human
speech and can even
 form simple sentences.
BIRD: I love you
OWNER: Good girl.
NARRATOR: But these parrots
 are also one of the few
 animals capable of reasoning.
They're able to
 figure out puzzles,
and even work
 together to solve problems.
Those are
 impressive bird brains!
Number three.
When it comes to evading
 predators squirrels are
 honor students.
When threatened they'll
 run in a zigzag pattern,
an effective mode of escape.
They're also
 acrobatic and intelligent.
Two.
They may wallow in the mud,
 but domestic pigs clean up in
the intelligence department.
They can learn tasks,
 like operating levers
 and even swim!
They've got smarts
 and good looks!
Number one.
Being playful is a
 sign of intelligence,
which puts dolphins near
 the top of the smart list.
Dolphins are known to ride the
 waves off of fishing boats.
Captive dolphins have been
 seen blowing bubbles from
their blowholes and then
 swimming through them!
They form their own tricks!
Now that's a pack
 of clever creatures.
