    Hi Guys,

    Not *my* pics but here is an idea of what is going on inside my eggs:
    http://www.testudinae.com/400_fotos/...imos_dias.html

    This is a spanish-based site so perhaps Mari can do some translations if she is feeling nice LOL.

    My torts are about that size/shape now, but obviously my eggs still have their shells

    So far, I've translated this, I'm a bit tired so will translate the rest later :

    Due to an accident in the last days of incubation of some indian star tortoise eggs, we could take photos of the activities and behaviour that the tortoise does before leaving the egg.

    We can see that in the 2nd images the tortoise is still within the membrane, it is in a state of total lethargy, absorbing nutrients from the delicate veins (probably capilliaries?) that surround the bag. The tortoise remains inactive whilst he stays inside the membrane, which is permeable and permits the exchange of gases from outside.

    Well Lucky you!! hahaha

    Here you go Josh

    The absence of Chalazas (have no idea what that is ok.. checked wikipedia ) between the egg and the alantoid membrane can be observed in these images. The embryo is developing completly free inside the egg. This is the first reason that when we touch or move the eggs they have to be left in the same position they were found at, otherwise, we may damage the embryo since it wouldnt be protected by the chalaza, and the tortoise could die.


    To prevent the loss of humidity and the embryo's dehydration we use a small plastci bag which provides a green house to keep humidity high around the half broken egg. The tortoise barely moves and is practically inactive and asleep.



    On the second day of the egg being broken the tortoise is a bit more active. The entrance of oxygen has helped the animal mature and the membrane sorrounding it is starting to break. The tortoise is still not active but moves by stretching its body from time to time


    (we'll keep going tomorrow, Tatiana just woke up and wants her milk!!])

    In the images above and belove we can see the caruncula? (false tooth use by all tortoises to break the egg) it is located below the nose. Aproximetly 2 weeks after their birth this appendix dissappears, since it is only useful for getting out of the egg.


    On the 3rd day, the tortoise can breathe outside of the bag. Its movements are slow. It is still absorbing nutrients and opens its eyes from time to time. The Alantoid membrane has completetly dissappeared.


    You can observe the huge size of the vitelum. The tortoise can barely move because of it, and continues to absorb nutrients



    On the 4th and 5th day the tortoise is still very calm. The vitelum is smaller and it opens its eyes for longer periods of time.


    On the 6th day the vitelum is smaller. The tortoise moves more and is more active. To prevent dehydration water if offered and the tortoise drinks it without problems.


    the water drinking elevates the torts activity level and it leave behind the egg. By moving for over an hour it is able to break the reminder of the egg.


    Outside of the egg, it rests for a long time. It is in perfect health and very active.


    Vitelum size when tort left the egg


    2 days after it has dissapeared

    there you go :)

    Thank you

    The carancula is an 'egg tooth' which is a tiny little white blip that torts have to break out of the egg. A vitelum is what we call a 'Yolk Sack' where they get all their nutrients from

    Thank you so much for translating
