EUROPEAN POND TERRAPIN (EMYS ORBICULARIS)

From Wikipedia, the free encyclopedia:

The European pond terrapin (also called the European pond turtle or European pond tortoise), Emys orbicularis is a long-living freshwater species[2] of turtle found in southern and central Europe, West Asia and North Africa. In the early post-glacial period, the pond turtle had a much wider distribution, being found as far north as southern Sweden.


The European pond turtle is a medium size turtle and varies quite a bit across its distribution, from 12 to 38 cm length. Its shell is brown with a hint of green, spotted yellow.

An important factor that affects Emys orbicularis development is temperature and thermal conditions. It has been reported that differential growth rates of the same species occur, including variation of body size and clutch sizes, because of varying temperatures in certain areas.

Emys orbicularis turtles eat a mixed diet of plants and animal matter that can increase the efficiency of their digestive process. Although it is assumed that Emys orbicularis turtles are strictly carnivorous, it seems that not all Emys orbicularis are entirely carnivorous as their diet also consists of plant material.It has been reported that an adult's diet starts from a carnivorous to a more herbivorous diet as it ages and grows in size. This is also very similar to other omnivore Emydidae turtles.

Most freshwater turtles lay their eggs on land, typically near a water body, but some species of Emys have been found to lay their eggs distances less than 150 meters from water. The search of a nesting areas by adult females can last several hours to more than one day. Once the location of the nest is established, females spend time for the construction of the nest, laying of the eggs, and closing the nest which can take up to another 4 hours.

Climate has an effect on the survival of Emys orbicularis hatchlings. Hatchlings are only able to survive under favorable weather conditions, but due to regular annual clutch sizes and long lifespan, Emys orbicularis adults, along with many freshwater turtles, balance out loss of hatchlings due to climate.

Emys orbicularis species have become rare in most countries even though they are widely distributed in Europe. The building of roads and driving of cars through natural habitats of Emys is a possible factor that threatens the populations of the European pond turtle. Road networks and traffic often carry complex ecological effects to animal populations such as fragmenting natural habitats and creating barriers for animal movement. Mortality on the road is most likely due to females selecting nests near roads which places a potential danger for the hatchlings as well. Hatchlings that wander too closely to roads are more likely to be killed and put the future population in danger.

Hi Marius,what a nice point of view,so low and so perfect...a very interesting and different way to take a turtle,excellents colors,sharpness and composition.Thanks for share,have a nice day,LUCIANO

Hello Marius,
Excellent way to photograph a turtle! ... I like the cut and the POV at the turtle level. Days ago, appeared in my yard a little ground turtle (yes, here in Venezuela this can easily happen in our backyards, ha ha ha ....) And I did some pics of this turtle, but I could not cut them, and even I think my POV was incorrect. Now, afer i see your picture of a turtle, I'll have better luck next time! Very thanks for sharing this shot, is a very beautiful turtle, portrayed with good taste and best technique. TFS, Regards.

PS: Very useful note also.

Buna
Fain portret! Ma mir ca mai supravietuiesc, aici sunt multe balti invadate de exoticele broaste testoase cu urechi rosii de California.
Numai bine
