inmany ways. One of thesemanifstations is the amazing speed animals
use to survive, sometimes to run away and sometimes when they have to
chase.
What are the fastest animals in the world?
What are the characteristics of these animals?
Fastest Beings In The Air
Birds are the fastest animals on earth. That friction force is less
in the air has a big impact on birds being the fastest creatures. The
fastest among birds is the tercel, which is as big as a crow. The
speed of this little bird, which flies 320 kilometers per hour, is
equal to the latest speeds of cars such as the Lamborghini Murcielago
Convertible, which is the fastest production car in the world, and
Formula 1 racers.
These beings first climb in the air and then dive on their prey flying
underneath them at a speed of 320 kilometers per hour, using a special
hunting technique called "diving." Then they suddenly catch the prey
that dies as a result of this impact in the air and this ends the
hunting process. These beings gain this amazing speed only when they
dive to the ground for hunting. There is no doubt that the speed of
this bird, that reached a record speed in the air when compared to
other birds, and the ability to calculate the impact point or catch
its prey in mid-aircannot occur coincidentally. Besides these, birds
of the falcon species need to be able to see their prey from very far
distances in order to maintain its life. This couldonly be ensured
with the visual acuity of falcons being seven times sharper than
that of man. This speed of falcons is, no doubt, a wonder of creation
that makes them perfect hunters and are a result of Almighty Allah's
superior creation. They could only fly because Allah, the All-Knowing,
inspires them to fly this fast and because He created the necessary
systems in their bodies. In one verse, this truth is revealed as
follows:
" Have they not looked atthe birds above them, with wings outspread
and folded back? Nothing holds them up but the All-Merciful. He sees
all things. " (Surat al-Mulk, 19)
Fastest Beings in Water:
All sea creatures from the tiniest fish to the biggest whale move
easily with a superior maneuverability , swim with the highest
efficiency by masterly using their body weight and easily feed. The
reason for this is that the swimming system of every fish species is
created in a perfect manner. The location of their fins is specially
selected, the size of their gills and the indents on their skins have
the characteristics that meet their needs perfectly.
The way a fish swims looks like the working system of machines. Almost
all machines move around a fixed axis with a fixed rotation speed and
produce power via pieces called shafts. Fish also produce power, but
their working system is much different than that of machines. Every
single crank in fish is connected in such a way that movement takes
place on a single plane. Therefore, the fish's spine moves right and
left continuouslylike a snake curling on the ground. The fish's speed
offorward movement is also directly proportional to the right-to-left
traffic speed of the axis of the finalong the fish's spine. When the
fin gets close to the axis speed increases and when it is away from
it, it decreases.
Sudden acceleration is vital for fish, because they need this
capability both to hunt and to run away from predators. Some small
fish can reach their maximum speeds in a short time like
one-twentieth of a second.The thrust they produce inthe meantime is
four times their own weight.
This means sports cars reaching 100 kilometers from 0 kilometer within
4-6 seconds, but normally such a thing is impossible because cars need
more time to reach their maximum speeds. However, for fish the time we
mentioned is only one-twentieth of a second.Besides all of these,
there is also another point that needs to be mentioned. Fish also show
this superior performance sometimes swimming against currents. When
it is considered that water's resistance is far more thanthat of the
air, it can be understood that fish have an extraordinary performance.
Some examples about this superior performance of fish are as follows:
The best example about this subject is no doubt the Mediterranean
spearfish. The Mediterranean spearfish, which looks like a swordfish
and has a very large dorsal fin , is the fastest creature in water
with a speed of 110 kilometers per hour. This fish, which has a total
weight of 100 kilos and a height of 3.4 meters, feedson smaller fish
and cuttlefish, thanks to its strong fins and aerodynamic qualities
andcan also escape from sharks easily.
