DOLPHIN WITH SMILING FACES
No
other animal is as pleasant and friendly towards human beings
as are dolphins. Their docility and friendly manners are obvious
from their faces.
During delivery, first the tail, then the body
and finally the head of the baby dolphin appear. In order
to feed it, the mother dolphin contracts and loosens her milk
glands, thereby spraying her milk into its mouth. You can
compare this to squeezing a plastic bottle with your hands
to spurt out the milk it contains.
Mammals
do not need this spraying system to nurse their young. However,
such a method is essential in water. Could the mother dolphin
herself think up and develop such a system? Could it be possible
that she felt the necessity for such a system and supplemented
her milk glands with muscles? As you can imagine, this is
implausible! As we stressed earlier, Allah created the body
of the mother dolphin in a manner that is extraordinarily
suitable for the baby dolphin’s needs.
The respiratory system of the dolphin is also
similar to that of human beings. Yet, unlike human beings,
its nostrils are not in the middle of its face but on the
top of its head. Like human beings, dolphins, too, inhale
air before they dive under water and they retain it in their
lungs and then dive. While they rise from deep underwater,
just a few metres before they surface, they will breathe this
air out forcefully through their blowhole.
You
have probably seen on TV how effortlessly dolphins swim in
water and even race with ships. They are perfect swimmers.
Their smooth slippery skin is the most important reason why
they are able to swim so perfectly. These features help them
to glide through water and swim very fast. Another feature
enabling the dolphin to swim fast is its nose, which is called
a snout. A dolphin’s snout has the most appropriate shape
for fast swimming and has even served as a model for the design
of ships. Thanks to this feature, our ships sail faster today
than previously.
Do you know that dolphins are bereft of a sense
of smell and that they are blind? However, Allah has granted
them a very advanced sense of hearing. Dolphins can hear sounds
from kilometres away. In addition to that, by means of a system
existing in their body that resembles an apparatus used in
submarines called "sonar", they can easily find their way
and determine their prey’s location. This system operates
as follows: The sounds produced by the dolphin, which are
inaudible to the human ear, spread in the form of underwater
sound waves. When these sound waves meet a barrier, they hit
it and bounce back. The time taken for the sound to strike
a fish or a rock and bounce back shows the distance of the
prey or the barrier. This system of dolphins inspired scientists
to develop the sonar systems used in submarines.
The dolphin’s strong sense of hearing protects
it from falling prey to other fish in the ocean. .
