Alligator spotted in Florida orange
The discovery of a tourist in Venice. Incerti scholars. And there are those who think a publicity stunt
Milan – Florida is famous for its orange groves, less for orange alligators. Until now: Venice a tourist has discovered and photographed the first example of an unusual hue with alligator. Experts from the state wildlife commission are working to see if the color is genetic or a further step in the evolutionary scale of reptiles.
While he was returning from work, Sylvia myths, settantaquattrenne one of South Florida, found in a canal in Venice in the woods what appears to be the world's first alligator orange. He captured with his cell phone and sent the photo first to the grandchildren in Indiana and then to the local media. Who promptly took over the strange news. Perplexed at first biologists and experts: some argue it could simply be a copy for half albino.
reptile eggs
The egg of reptiles is very similar to that of birds, both in composition and as such development even if, all’interno, not possess an inner tube and are usually symmetrical in shape. E 'thus formed:
- un shell limestone permeable to oxygen that enables air-breathing and prevents dehydration; generally soft consistency, consists of a membrane pergamenacea the corion covered more or less (There are also strict eggs) from this calcareous
- an underlying membrane, real innovation of the reptiles to conquer Earth, that protects it from dehydration and compression
- un albums gel that provides additional nutritional reserves (Protein) for the embryo , mechanically isolates the, it moisturizes and protects it from microbial infections
- a large egg (The yolk or yolk sac), rich in complex nutrient that calf (lipids and proteins)
- membrane, this allantoide, that has a dual function: urinary bladder In fact, the urine of reptiles (like that of birds) is semi-solid; where the membrane comes into contact with the shell, metabolic exchanges occurring between carbon dioxide and oxygen.
Fertilization is internal, and embryonic development occurs in amniotic sac where it is protected from drying, bumps and the thermal shock.

Reptiles
The reptiles had their origin from primitive amphibians and their advent marked the final conquest of land by vertebrates, who achieved complete independence from the water, through the acquisition of a breathing mode of single lung and reproductive released by the element in the whole liquid.
Reptiles are the first group of vertebrates adapted to a strictly terrestrial environment.
