As we said earlier, the turtles usually stay underwater for a few minutes during their usual activities. However, if there are any disturbances and changes in their habitat, they will require more oxygen for breathing. That is why it is crucial to control the water temperature in the turtle tank on the comfortable level of the pet sea turtle. You may find the turtle underwater for hours during the nights when it is sleeping.
A variety of aquatic turtle can hibernate underwater in the northern areas. It usually swims to the bottom of the waterside and covers its whole body with a substrate. The metabolic rate of the turtle starts lowering, requiring very little oxygen and food to survive in this period. A turtle can keep its breath when it is hibernating. Turtle can also absorb some oxygen from the water using their specialized throat and cloaca in a smaller amount.
The sea turtle requires to hold the breath for an extended period while diving deep in the sea to search for food. Most species of the sea turtle can jump around m or ft. However, the leatherback species can unbelievably go up to m or ft deep. They become possible because of their flexible shell and collapsible lungs.
More so, the species of turtle can also store more oxygen in its blood and muscles. The leatherback turtles are also adopted in the cold environment. As a result, they can dive into cold water without getting cold-stunned. More so, the body can also retain warmth because of its dark color and fatty tissues with oil that works as a heat observer.
The turtles can decrease their heart bit rate to a significant level to keep underwater for an extended period. As per the researcher, there can be a nine-minute difference between the heartbeats of the turtle, which assists in staying underwater for a long time.
These turtles also have a better metabolism rate, which helps produce a lot of heat while active. These things help the sea turtles to hold the breath underwater. Learn More.

Most sea turtle researchers believe that the black sea turtle should be called the Pacific green turtle because it is a sub-species of the green sea turtle and, as a result, has almost identical genetic traits. Some sea turtle researchers believe that the physical characteristics and other behavioral difference indicate that it should be classified as its own species. How do hatchlings and adults locate the ocean?
They are guided by the brightest light, which is usually moonlight reflecting on the sea. Turtles avoid shadows, including dune vegetation at the top of the beach, places where danger could lie. What do sea turtles eat and do they have teeth? Each species feeds on a diet specific to that species. For example, loggerheads feed mainly on hard-shelled organisms such as lobsters, crustaceans, and fish.
Green turtles prefer sea grasses, while leatherbacks feed primarily on jellyfish. Hawksbills have a hawk-like beak that is used to cut through tough coral, anemones and sea sponges. Loggerheads have powerful jaws that crush shellfish and mollusks.
How deep can sea turtles dive? Leatherbacks can dive to a depth of more than 1, meters 3, feet in search of their prey, jellyfish. The hard-shelled species dive at shallower depths. The leatherback is adapted to deep dives because of its unique morphology.
Unlike other sea turtles, the leatherback lacks a rigid breastbone that allows it to collapse during deep dives.
There is a large amount of oil in the skin and the leathery shell absorbs Nitrogen, reducing problems arising from decompression during deep dives and resurfacing. How long can a sea turtle hold its breath? And why do they drown? As sea turtles are air breathing reptiles, they need to surface to breathe. Sea turtles can hold their breath for several hours, depending upon the level of activity.
A resting or sleeping turtle can remain underwater for hours. Recent research has shown that some turtles can even hibernate in the sea for several months! However, a stressed turtle, entangled in fishing gear for instance, quickly uses up oxygen stored within its body and may drown within minutes.
How big was the largest sea turtle ever recorded? The largest species of sea turtle was the Archelon, which measured 7 meters about 21 feet in length and lived during the time of the dinosaurs. Today, the largest living species is the leatherback turtle. Atlantic leatherbacks are slightly larger than the Pacific population. Leatherbacks measure, on average, 2 meters 6 feet in carapace shell length.
The largest leatherback ever recorded was a male found stranded on the Welsh coast in He measured almost 3 meters 9 feet from tip to tail and weighed kg 2, lbs. How are sea turtles tracked in the ocean and how long can they be tracked for? Researchers track sea turtles through using satellite telemetry.
The transmitter emits signals of information to an orbiting satellite when the turtle surfaces to breathe or bask. Data, received over a period of time, allows for tracking a turtles movement patterns and swimming speed. Usually, satellite transmitters are attached to females that come ashore to nest. Tracking has provided important information on migration routes between breeding and foraging feeding habitats. The time length of tracking depends upon how long the device remains on the turtle and on battery life.
Tracking usually continues for months, although cases have been reported exceeding 2 years. After about two years, the transmitters fall safely off the turtles. What are the methods used to tag sea turtles? There are three primary methods of tagging sea turtles. These tags are clearly visible, each containing a unique serial number and the address of the organization applying the tags. Each PIT tag also has a unique digital serial number and requires the use of PIT scanning equipment to display the tag number.
While PIT tags are more secure than flipper tags, their higher cost and the need for specialized equipment limits many researchers from using them. Why are sea turtles tagged? Sea turtles are tagged for several reasons. Flipper and PIT tags are used to identify individual turtles to help researchers learn things like nesting site fidelity, the number of nests laid during a nesting season, the number of years between nesting seasons, and growth rates.
In addition, these tags can be used to identify where a captured or stranded turtle was originally tagged, which can be used to establish possible migration pathways. While flipper and PIT tags can provide starting and ending points for migration, satellite tags are able to provide research and conservationists with the actual routes that sea turtles take between different habitats.
