Animals Healers and Alarm Raisers
This
short article will briefly detour around a few unique ways
of healing that animals have evolved and also explore some
of the tricks and traps that animals have some species of
animals have developed to stun, baffle, frighten their enemies.

Meet
Dr. Chimp and other animal doctors
If you think that if a wild animal left alone
may not be able to heal itself, you may be in for
a big surprise. Chimps and other animals of the rainforest
know how to heal themselves very well. For example,
if a chimp is in pain, it knows exactly which leaves
to eat.
|
This
knowledgeable behaviour about herbal medicines is not just
limited to chimpanzees but also other primates, like baboons,
lemurs and vervet monkeys.
A
chimp's prescription for diarrhoea
If it has diarrhoea, the chimp will go over and pick up
some leaves from of the Aspilia plant to treat itself. The
leaves of this plant help to even eliminate parasitic worms.
A
chimp's prescription for abortion
It is interesting to observe that many of the medicines
used by the chimps are the same as that used by the primitive
tribal people of that area. For example, in order to induce
abortion, chimpanzees chew Combretum and Ziziphus leaves.

How
baboons cure dysentery and diarrhoea
Baboons are seen chewing leaves of Solanum indicum
while if they suffer from sever infestation with Shistosoma
worms, a harmful gut parasite, they go out an chomp
the fruits of the Balanites tree.
How
female baboons handle the pain of menstruation
Menstruating baboons even have a treatment for period
pains, taking the leaves of the candelabra tree to
ease their discomfort.

poisons.

Alarm
Raisers!
Lizards which throw blood!
Just
imagine being a small vulnerable lizard. One would
think that there's very little that a harmless little
lizard can do when caught, except understand its limitation
and role in the food chain. However, that's what most
lizards do, try to escape after detaching their tail
or gallantly give up their life if they cannot scurry
away fast enough.
|
However,
far away in Texas, there's a breed of lizards that really
brave it out and give the offending intruder a real scare.
When attacked the Texas horned lizards inflate themselves
and burst the walls between sinuses and eye sockets, squirting
out jets of blood from their eyes. The awfully frightening
fountains of blood actually spurt out for a distance of
more than a metre.

Hawkmoth
that does a snake dance!
Caterpillars look like diminutive, hungry worms
that have go on non stop leaf munching binges for
their lunch and dinner. Frail, small creatures, caterpillars
make easy prey for many birds, frogs and other large
insects. However, there's a family of caterpillars
that can make any animal's hair stand on end with
its truly alarming display.
|
The
hawkmoths are when attacked puff themselves up until one
end of their body begins to really look appear like the
head of a snake. The caterpillar then sways its 'snake head'
part of the body to and fro. That makes the attacking animal
think that here's a live and kicking snake that's going
to go out and strike very soon.
 |
Hissing
butterflies!
From caterpillar to butterfly, here's another
surprise. Delicate and dainty, butterflies look like
nature went out to explore the world of lines,colours
and beautiful patterns. The number of different butterflies
with their unique patterns and colours is simply amazing!
|
However,
one butterfly that really takes the cake for alarm strategy
is the peacock butterfly. When this butterfly is threatened,
it opens its wings to display large eye spots that look
suspiciously like a snake. To complement the mimicry repertoire,
the butterfly makes a distinct snake like hissing sound.
 |
The
snapping turtle that shows a worm
Turtles and tortoises look so much like peaceful,
lovable creatures that just go about living peacefully
for hundreds of years. However, a turtle species -
the snapping turtle has devised a unique way to make
finding food easy.
|
When
the snapping turtle opens it's mouth, it reveals a small
fleshy, worm like structure. The turtle which looks like
a log, could easily make a gullible predator go for that
harmless worm.
Hog
nose snakes that throw up foul meat smells and fluid
Snakes that are not equipped with venom glands have
evolved other ways of looking threatening and finding food.
The hog-nose snake when threatened release fluids that have
the distinct smell of a rotting carcass.
 |
The
wood snake that stinks like dead flesh
Another species of snake that also exhibits a
similar strategy is the West Indian wood snake. The
snake coats its scales with a fluid that stinks of
decomposing flesh. When attacked it has special blood
vessels in the eye which burst to redden the eyes
and cause blood to run from the gaping mouth.

The
praying mantis that dresses up as an orchid
Another insect which is just as vulnerable like grasshoppers,
ants and caterpillars is the praying mantis.A beautiful
way of camouflage that this insect has devised is
to resemble the beautiful and colourful petals of
the ichneumon orchid.

Sound
laser stunners!
Moving from visual mimicry to sound, there is quite
a lot of special effects that animals use to stun
and alarm other creatures when threatened. Dolphins,
and sperm whales used sound waves to disorient, stun
and kill their prey like fish and squids.
|
They
do this through the use of the 'melon' structure on their
head to shoot out a narrow beam of sound.
 |
Moths
that speak sonic
Moving
from the submarine creatures to terresterial animals
that use sound, there is a rich diversity once again.
Besides the bat families that use sound to navigate,
moths too use sound. A species of moth has used sound
in a very interesting way. When hunted by a bat, this
species of moth gives out a sharp, ultrasonic squeak.
That makes the bat drop the prey instantly out of
fear, shock and surprise, thinking that it has banged
in to something.

Surrogate
ant mothers and nurseries for large blue butterflies
Ant
have a very interesting, elaborate and complex social
organization. Not many insects exploit the ants interesting
chemical means of communication. However, one insect
that does that with good results is the large, blue
butterfly.
|
The
blue butterfly uses the ant's nurturing qualities to its
advantage.By
giving out certain chemicals, it gives the ants a false
message that it is one of their own. Once, the message is
given by the large, blue butterflies, the ants go out and
bring them in to their nest and nurture them as one of their
own.
