Waves, come sweep my pasts away. Let them be part of your water cycle one day. Away, you leave me to come back some day. Like the droplets in the air and ray. Stay, be with me and don't go away. Show me how much time has been making me grey.

The tortoises have appeared an order of the reptiles and for the first time before more than 220 million years in the Karnium.

In Europe there are beside the sea tortoises only seven autochthonous kinds, three land kinds and four turtle kinds. Germany, Austria and Switzerland accommodate only one single local tortoise's kind, the Nominatform of the European terrapin.

For tortoises the tank which already puts out approx. 30% of the weight shows certainly the anatomically deciding characteristic feature. No other vertebrate shows a comparable anatomy. Like the Exoskelett of the insects, surrounds the tank of the tortoises who consists of the back tank and abdominal tank, all important organs and regions.

Tortoises see very good. They can differentiate colours even better than people, because her eyes show four different colour receptors like with all reptiles. They are thereby able to perceive also parts of the close infrared radiation and ultraviolet ray. However, grey tones seem to differentiate them less.
