1
secreture called leatherback turtle.
2
Janet O 'Vanakin of Florida Atlantic University has shown that they are the voltages of the leatherback's streamlined shape.
3
Swimming leatherback turtles have a lower drag, more efficient than other species indicating more efficient force.
4
To swim at the same distance to other sea turtles of the comparable size and weight, leatherback turtles spend on average 20 % less energy.
5
Among all the deep diving animals, the champions have always been assumed to be the marine mammals, the great whales and airless seals.
6
Our recent investigations, however, suggest that leatherback sea turtles may also be ranked among the ocean's greatest air -breathing dive reptiles.
7
While mirroring the dives of the leatherback sea turtles near St. Crocs, In the U .S.
8
Virgin Islands, scientists recorded a 650 pounds female ascended to more than 3 ,000 330 feet and remained there for 37 minutes.
9
High pressure also poses a challenge to the deep diver in terms of strong forces that could compress the chest.
10
causing broken bones or tissue damage.
11
Unlike its hard -shelled relatives, Leatherbugs has a softer shell made up from widely separated ribs embedded in thick tissue.
12
and whole structure is overlaid with a leathery skin.
13
How do the deep diving animals, whales, seals, penguins, and leatherback turtles avoid decompression, sickness, and other hazards while they dive to the great depths,
14
even sleep for a long period of time?
15
Many of the deepest diving marine mammals have a small lungs
16
and falsely exhale before diving in addition to reducing the balance so that they can dive more easily.
17
This severely limits the amount of nitrogen in their bloodstream.
18
One reason the leatherback ranges so far may be to specialise the diet
19
This giant of the sea feeds mainly on jellyfish full of high protein
20
and other useful minerals that are required during the day.
21
Although the variety of jellyfish and related prey are abundant, They are eaten by few other animals.
22
As one might suspect, a lifespan eating mostly jellyfish requires some special adaptions to make the job easier.
23
During the 1984 and 1985 nesting seasons, With the assistance of scientists, attach the recorders to 10 female leather bags that just laid eggs.
24
As a result, we are able to monitor the pattern of migration in Atlantic Ocean, when they return to the sea.
25
Some of the longest travel recorded for many animals have been made by this marine turtle.
26
In 1970, a female leatherback was tagged when she nested in Surami on the northeastern coast of South America.
27
Less than one year later, she was captured off the coast of Ghana, West Africa, having traveled 3 ,700 miles across the Atlantic Ocean.
28
Upon returning to the surface, the turtles change a quick breath and immediately hanging the street down again.
29
Little or no time was given to sleep or rest.
30
We then begin to track and tag the turtles when they swim back to the surface.
31
On closer examination, we notice the difference in dives depending on the time of the day.
32
Night dives were shallower with less in depth than day dives.
33
Leatherbacks are such swimmers that they rarely stop moving a behavior that has made it impossible to keep them in captivity.
34
The front flippers and more than half the lens of Ditto's body and the generated power from huge muscles.
35
which can account for 30 % of the animal's total body weight.
36
Since leather bags cannot easily be studied in captivity, researchers have been developing methods of studying them at sea.
37
They use the recorder, an instrument capable of recording location and the depths in C.
38
developed by Gerard Kuhlman of Psychological Research Laboratory.
39
The device has been used to study diving marine animals.
40
Why they keep diving, scientists soon realized that the turtles were probably costing much of the energy to follow their food source.
41
In tropical waters, jellyfish are most common at great depths in a biological zone called the deep scattering layer.
42
Discovered shortly after development of the sonar,
43
This zone consists of a layer of zooplankton below 1 ,800 feet during the day and migrates to the surface at night.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
