When female turtles lay their eggs, they often return to the beach they were born on or a deserted beach they have found. Often the eggs are laid on high ground or just above see level. This is so the eggs are safe from predators like sharks. Unfortunately once the eggs hatch they are at risk of birds and crabs eating them. Another adaption, once the eggs are hatched, the young baby turtles head straight to the water in hopes to get into the water to find their mother. Additionally the first thing the newborn turtles do is dive down to eat seaweed. Most turtles chose what kind of seaweed or sea plant they eat, however most turtles prefer to stick to seaweed. Turtles have many unique abilities that allow them to survive and thrive in their environment. These adaptations are a result of evolutionary changes over time. Turtles have developed behaviors that help them find food, avoid predators, and conserve energy. They also use their shells to protect themselves from danger. By understanding the behavior of turtles, we can better protect them and ensure they continue to inhabit our world for generations to come. Turtles have been around for millions of years, yet their behavior is still not fully understood. From sea to land, these creatures display a variety of behaviors that are highly complex and often perplexing. Despite their seemingly simple nature, turtles demonstrate complex behaviors that can be observed in different contexts and environments. In this article, we will delve into the complexities of turtle behavior and explore how researchers can analyze their actions in order to gain new insights.
WHAT ADAPTATIONS DOES THE TURTLE HAVE TO HELP IT SURVIVE IN THE FRESHWATER BIOME?
The fresh water biome is an aquatic ecosystem that has very little salt content in comparison to the marine ecosystem. Animals in this ecosystem have some adaptations which allow them to survive and thrive in this type of biome. The fresh water biome is the natural habitat of the freshwater turtles, which have evolved or adapted to live in this biome.
Heart:
The heart of the fresh water turtle has evolved for prolonged periods of diving. According to Science Magazine, the heart of the freshwater turtle has a functional ventricular septal defect. This adaptation allows the turtle to shunt the flow of blood from its left to right ventricle when it is on land. When the turtle engages in prolonged diving, the blood is shunted into the aorta directly. Science Magazine states that this adaptation allows the turtle to use anaerobic glycolysis as a sole source of energy during such long hauls of underwater diving.
Swimming:
Freshwater turtles are strong swimmers. They have modified hands and feet that have become flippers. These flippers enable them to swim and dive. The neck of the freshwater turtle is fused to its body by thick connective tissue, an adaptation that reduces drag and increases the turtle’s ability to swim effectively. Another adaptation that enhances a turtle’s swimming ability is its streamlined shell. The shells of freshwater turtles are softer and flatter than those of terrestrial turtles. This structure reduces drag and helps the turtle swim better.
Diet and Hibernation:
Freshwater turtles usually eat aquatic vegetation and small organisms like crustaceans, fish, insects and algae. Most species of freshwater turtles, such as the painted turtle, hibernate during the winter. They mate in spring and autumn and lay their eggs during the summer and late spring. Freshwater turtles usually lay their eggs on land. The turtle hatchlings instinctively migrate toward the water as soon as they hatch. Some of the freshwater turtle hatchlings may remain in the nest during the winter months and only emerge during the spring. The freshwater turtles have adapted to survive the cold winter months by developing thick skin that resists the effects of icy conditions.
Basking:
Freshwater turtles regulate their temperature by basking. They usually emerge from the water to bask on logs, other debris or on the sand. Most freshwater turtles bask several times a day. They may bask in the morning, return to the water to feed and emerge to bask some more. When night comes, they may drop to the bottom of a freshwater body, like a pond, and sleep.
HOW LONG CAN PET TURTLES STAY UNDERWATER?
Though all turtles breathe air, aquatic turtles such as sliders (Trachemys scripta) and painted turtles (Chrysemys picta) can stay underwater for quite some time. Because of their slow metabolisms and adaptations for extracting oxygen from the water, some species can even spend the entire winter underwater.
Basic Biology:
Turtles are ectothermic animals, commonly called “cold-blooded,” that warm their bodies via external sources like warm water and sunlight. While a turtle’s metabolic rate is always rather low compared to warm-blooded animals, it does fluctuate with the temperature. When the temperatures are cool, the metabolism of a turtle is slow; when the temperatures are warm, the turtle’s metabolism speeds up. The faster the metabolism is, the more oxygen a turtle needs.
Typical Behavior:
Most often, pet turtles will only stay underwater for a few minutes at a time. In warm temperatures, where most pet turtles are maintained, they must breathe regularly. At night, this may change as your pet’s metabolism slows a bit — sleeping turtles may stay underwater for a few hours at a time.
Scientific Data:
Few studies exist documenting the breath-holding behavior of turtles while at high temperatures — most work has been done on hibernating turtles. One exception is a study conducted in 1970 by C. Lenfant , et al, of the University of Washington. This study observed the breathing behavior of the mata mata turtle (Chelys fimrbiata). In the study, turtles held their breath for an average of 35 minutes when undisturbed.
Hibernating Turtles:
Some aquatic turtles from northern areas will hibernate underwater. Typically, the turtle swims to the lake or river bottom and buries itself in the substrate, at which point the turtle’s metabolic rate drops significantly and the turtle needs little oxygen and no food for a period of months. During this time, most turtles absorb some of the oxygen they need directly from the water via specialized structures in the throat and cloaca. Sometimes, oxygen levels in the water can drop dangerously low, particularly in extremely cold lakes. Snapping turtles (Chelydra serpentina) and painted turtles are able to survive in these anoxic waters by using anerobic metabolism and active chemical buffering processes.
Sea Turtles:
Scientists have studied breath-holding behaviors in sea turtles more thoroughly than in freshwater turtles. The leatherback sea turtle (Dermochelys coriacea), a species that frequents cold waters, holds the record for holding its breath — just over seven hours spent underwater. While the biology of sea turtles differs greatly from freshwater turtles, it’s possible freshwater turtles are capable of similar feats, even at high temperatures.
Diving adaptations in sea turtles:
Marine turtles are among the longest and deepest diving of the air-breathing vertebrates. In fact, these animals spend less than 10% of their time at the sea surface. The leatherback sea turtle , the best adapted to diving of sea turtles, reaches depths of over 1,000m, and voluntary dives of between 2 and 5 hours have been recorded. How do they do it? This is not fully understood today – it is very complicated to investigate these animals’ physiology in the wild without capturing them, which would in turn completely modify the animal’s behavior due to stress.
Sea turtles are anatomically adapted to life at sea completely hydrodynamic, with a shorter neck and a smaller carapace mass than its land and sweet water relatives, and non-retractile head and limbs. Their front flippers are flattened and are used for propulsion, while the back flippers, short and flat, work as a rudder. The nares are fully closed under the water to avoid water entering the mouth and respiratory system.
Great capacity to store oxygen:
When a sea turtle carries out shallow dives most of the oxygen is stored in the lungs, from where it goes to the bloodstream and tissues. However, for the deep dives, sea turtles depend on the oxygen stored in the blood and muscles. Sea turtles (especially the leatherback) show a high concentration of hemoglobin and red blood cells in the blood, and of myoglobin in muscles, which allows them to store a high amount of oxygen in the body, easily available for the tissues during the dive. The lungs also show a large surface for gas exchange, facilitating the entrance of oxygen into the blood with each breath. All this makes a sea turtle breath much more efficient than ours.
Good management of oxygen:
Sea turtles, as cold-blooded animals (they cannot thermoregulate and depend on the external temperature – with different aspects that we’ll explain in another post), show a slower metabolism than mammals. This allows them to resist longer with the same amount of oxygen than, for example, a seal. In addition, when preparing for deep dives, sea turtles activate a “diving reflex”, which allows them to reduce the heart rate and limit the blood supply to those organs and tissues that are essential for diving, thus further reducing oxygen consumption. Lastly, they are extremely tolerant to hypoxia. Especially the brain, which at least in the loggerhead sea turtle, and contrary to that of marine mammals, has been proved to survive up to several hours without oxygen.
And how can they stand the pressure at depth, which affects us so much?
Contrary to what it seems, the carapace of sea turtles is not completely fused with the plastron (the ventral part); there is a small space with connective tissue which allows for some degree of movement and compression. This comes to maximum expression in the leatherback turtle, which does not have an osseous carapace. Furthermore, the respiratory system (lungs and airways) of sea turtles collapses at depths of around 80-160m, reducing the problem of narcosis due to dissolved nitrogen, or decompression syndrome during ascend after long, deep dives. Some air remains in them, but in areas where there’s no gas exchange. Blood circulation into the lungs is also interrupted during diving. However, leatherback turtles have been seen to modify the time spent at different depths and to ascend slowly from deeper dives, avoiding thus the formation of nitrogen bubbles on the ascent.
Analyzing the Complexities of Turtle Behavioral adaptations:
When female turtles lay their eggs, they often return to the beach they were born on or a dessertad beach they have found. Often the eggs are laid on high ground or just above see level. This is so the eggs are safe from predators like sharks. Unfortunatly once the eggs hatch they are at risk of birds and crabs eating them. Another adaption, once the eggs are hatched, the young baby turtles heaad straight to the water in hopes to get into the water to find their mother.
