5 Animals That are Smarter than They Look! |
From counting and dancing to
incredible communication skills - these five animals may not look like
Einstein's, but compared to other animals of their kind - they are
geniuses.

Monitor Lizards - Counting and cooperation. |
Most of us wouldn't choose a lizard
as an intelligent creature, and most of them aren't. But the monitor
lizard is surprisingly smart. Studies have shown that this
dinosaur-looking lizard can count up to six! The smart lizard was
challenged like so: Every day it would be given a sequence of snails
(it's favorite treat) to eat. First 4 and then up to 6. The lizard,
after eating, would be led to another room with 4 more snails.
However, when given only 3 instead of
four, the lizards continued to look for the missing snail, even when
given access to the 'bonus room'.
These lizards are also known to
cooperate with each other to get food. One will lure a crocodile
(usually a female) away from her nest, while the other lizard will go in
and dine on the tasty eggs. How about that for smarts?

The Honey Bee - Cognitive map, communication dance and navigation. |
The honeybee may look like a simple
creature, but it belong to one of the most complex social systems of any
known animal, and has been studied more than most mammals (the honey
may have something to do with that). Despite all this research, very
little is known about the actual honeybee intelligence.
The most fascinating and
controversial issue about the honeybee intelligence is what's called the
'waggle dance'. When a honeybee comes back to the hive after it has
found a source of food, honeybees break into a bizarre and elaborate
dance before they go and collect others to get the rest of the food back
to the hive.
Researchers have spent years studying
this dance, and have suggested that hte dance may be an encoded message
that gives precise instructions to the other bees about where to find
the food and how far it actually is. These variables are based on
changes in the angle of the dance, the speed and the time of day. Others
claim that the dance is just to draw attention, and the real
instructions are given by odor.
Other than this form of
communication, honeybees are smart because they can maintain a map in
their haed of the surrounding environment, including any objects on the
way. They can discriminate between colors. When presented with two
colors - one that leads to food and one that does not - honeybees
learned incredibly quickly to choose the right color.
However, for all their intelligence,
the honeybee memory is about 5 seconds long, so the beed doesn't have
much time to make a decision!

The Portia labiata Spider - Smart Hunter |
This little spider is a jumper which
is mostly found in Southeast Asia. It is commonly referred to as an
'eight legged cat' because of how clever and creative it is when
hunting. The Portia Labiata spider can learn from his mistakes -
literally avoiding techniques that didn't work for it in the past and
trying, by trial and error, to come up with better ones.
An example of how smart it is? The
portia Labiata sometimes stalks other spiders. It does so by using the
web against the spider that made it. By plucking on the strings of the
web in a very specific way, the Portia spider mimics the vibration a fly
would make, and so the other spider comes rushing out to get to its
prey - only to find the Portia Labiata spider pouncing on him!
So if you ever shrink down 10 times your size by a mad scientist, avoid this clever hunter at all costs!

African Hornbill - Speaks 2 Languages |
The African Hornbill is one of the
only animals on earth that speak more than one language. Apparently,
this bird has learned to speak monkey. Or most accurately - Diana
Monkey.
A study found that the African
Hornbill is able to understand the warning calls that monkeys sometimes
make at each other, to warn about a predator. The hornbill will even
ignore calls about threats that don't concern it - like the sound
monkeys make to warn of a leopard, and only respond to those that may
threaten it directly.
|
Vampire Bats - Good deeds for those who did for them. |
Vampire bats scare many people. They
are, after all - a parasite. But even parasites, apprarently, are able
to not only work together, but even do each other favors!
Yes, a study by Gerald Wilkinson
showed that bats share food with other bats who are hungry, and not only
that, but they keep score of who shared with them in the past, and are
much more inclined to share with them than with anyone else.
