Snake-Necked Turtle (Chelodina longicollis)

Snake-necked turtle (Chelodina longicollis) characterized by long necks that can bend and move in a serpentine fashion. Snake-necked turtles are a group of side-necked turtles with necks that range from nearly as long as to slightly longer than the shell.

In fact, they inhabit the waterways of Australia and southern New Guinea and possess the longest neck of any group of turtles in the world. Because the neck is so long that it cannot be retracted completely beneath the margin of the shell. There are six species of turtles belonging to the genera Chelodina and Macrochelodina in family Chelidae,


All aquatic turtles are great swimmers

Rather than swim, these reptiles prefer to walk along the bottom of streams. The aquatic turtles are carnivores and prey on fish. When hunting the reptile holds its neck against its body. When prey is close, the neck and head lunge forward, and the animal opens its mouth and throat to create a vacuum. Water and prey are sucked into the mouth, which snaps shut. The mouth then opens slightly to allow water, but not the prey, to escape.
While all snake-necked turtles are egg layers. The northern snake-necked turtle(Macrochelodina rugosa), lays its eggs in nest chambers beneath the water. The embryos immediately go into diapause after the eggs are deposited.  While they resume development only when the nesting chamber dries. As a result, the eggs hatch 9 to 10 months after egg deposition just as the rainy season begins.

The common snake-necked turtle                  (Chelodina longicollis) is found from Queensland to South Australia.

The common snake-necked turtle prefers freshwater rivers, lakes, and swamps with soft sand and muddy bottoms. Seems like they feel more relaxed with plenty of plant cover above the water and submerged stumps and tree branches below. Because it is a basking species, add a large branch that rises out from the water’s surface. Without a proper basking spot, turtles cannot dry themselves appropriately or shed their old shells. As a result, turtles can develop shell and skin problems, such as shell pyramiding. Turtles also easily get a fungus on the shell if they do not bask often enough.  Other reasons water turtles need to dry off is because leeches are a blood-sucking ectoparasite that can cause anemia in reptiles. Drying out in the sun causes the leeches to shrivel up and die. Algae on basking aquatic turtles can also dry out and fall off, allowing the shells to retain their aerodynamic nature.

Chelodina species, C. longicollis

The average lifespan of Chelodina longicollis ranges from 31 to 37 years.  The lifespan of wild and captive individuals appears to be approximately equal; however, very few have been held in captivity. While the snake-necked turtle reaches 10 inches in total shell length. Consequently, what makes this turtle unique is its neck is nearly as long as its carapace. The common snake-necked turtle’s carapace is broad and flat, and it is typically dark brown to black in color. In contrast, the plastron is yellow with black lines following the seams.
Much as many aquatic turtles, common snake-necked turtles emit a foul-smelling liquid from their musk glands as a defense against predators. The smell is similar to that of a skunk, and it’s amazingly potent for such a small turtle. In fact, this obnoxious odor is no doubt an effective deterrent to a curious dingo or monitor. Most noteworthy, Snake-neck turtles often stop exuding this musk in captivity.

Do Turtles and Tortoises Ever Sleep.

Many turtles, tortoises, and terrapins appear to sleep during a daily cycle. They pick a secluded spot with a constant, acceptable temperature; these reptiles then stop moving around and assume a particular posture, usually withdrawing into their shell for protection during “downtime.”

We caught Popeye again yesterday as he was going in for a nap in the afternoon. However, does he ever rest or even sleep? Humans sleep differently than turtles and tortoises. Consequently, turtles are more like in a resting state. Much as it depends on the species as to how they rest.


If They Do Not Sleep… Are They Tired?

Of course, sea turtles can sleep on the surface of the water when far out on the ocean deeps, Also, they wedge themselves under overhanging rocks or coral outcroppings to rest in shallow water. In fact, when they are inactive, sea turtles can remain submerged for three hours or more without needing to surface for air.
Painted turtles bury themselves in sand or mud at the bottom of a pond to sleep. Therefore, absorbing oxygen from the water. Hense, semi-aquatics, such as the map turtle, may dig themselves partially or completely into a marshy area of grass or moss.

Do they hibernate?

Many turtle species live where they need to hibernate through the winter. A hibernation is a form of deep sleep from which the animal cannot be awakened easily. Almost all of its bodily processes slow down. As a result, it does not eat when no food is available.
Much as, in the Southwestern United States, the endangered desert tortoise hibernates during the coldest part of the winter in an underground den. While it comes out to warm up on mild, sunny days. The giant tortoises of the Galapagos and Seychelle Islands do not need to hibernate, but they do sleep during the cooler nights and often up to 18 hours a day, moving around only when they get warm enough.

The Difference Between…                                                                                       Hibernating Mammals and Brumating Reptiles 

Hibernation and brumation are really very closely related, they are periods of dormancy during which an animal becomes physiologically less active, their metabolic processes slow down, and growth stops. However, mammals and reptiles go into dormancy is slightly different ways, thus the terms hibernation and brumation.
Both reptiles and amphibians prepare for dormancy by eating more. They build up fat reserves in their bodies that can help them survive. Unlike mammals, the reptiles also build up a high level of glycogen in their body tissues as well. Glycogen is a form of polysaccharide or sugar that can be used as energy for muscles. When mammals enter hibernation they rely solely on their fat reserves as energy to see them through winter. However, reptiles do not use fat as their sole source of energy. They mostly use the glycogen in their muscles with their fat reserves playing a greater role in reproduction, egg development, and post-dormancy mating

It’s even thought that some reptiles need brumation to trigger reproductive processes such as egg and sperm production.

Here’s a quick comparison chart:
Hibernation (Mammals)Brumation (Reptiles)
Caused by shortening day length and temperature changesYESYES
Animal may feed heavily before entering dormancyYESYES
Build up of fat reserve and lipids before entering dormancy? YES YES
Feeding and eating stop during dormancyYESYES
Drinking Water StopsYESNo
Decreased heart rate, body temperature, and metabolism slow or decreaseYESYES
Use stored fat for energy during dormancyYESYES/NO (glycogen)
Anoxia Tolerant (low oxygen)NOYES
True SleepYESNo
Punctuated ActivityNO (most)YES
