Necesitas un CITES para tener Macrochelys porque aparece en el anexo C del reglamento 338/97 de la UE y en la modificación de 2013 (no de 2012 como te dije antes). Los CITES son necesarios para la tenencia individual y privada de animales del anexo C, tal y como puedes ver aquí abajo:
1.6.6 Personal ownership certificates
Personal ownership certificates, (Arts. 37 to 44 of Commission Regulation (EC) No 865/2006), are used only for live animals listed in Annexes A, B or C of the EU Wildlife Trade Regulations that are held for personal non-commercial purposes. Personal ownership certificates are not issued for plants or dead animals, their parts or derivatives. A personal ownership certificate may be used more than once, providing that all conditions are met, thereby precluding the need for application for CITES permits each time an international border is crossed.
A personal ownership certificate can only cover one specimen. Personal ownership certificates may only be issued for legally acquired live animals held for personal, non-commercial purposes.
A personal ownership certificate may be used in lieu of an import permit. If the country of destination agrees, it may also be used as an export permit or re-export certificate. The specimen must be accompanied by the owner when crossing an international border.
Where the specimen originates within the European Union, it is the Management Authority of the Member State in whose territory the specimen is located, which is in charge of issuing the personal ownership certificate. Where the specimen is introduced into the European Union from a third country, the issuing authority for the personal ownership certificate is the Management Authority of the Member State of first destination. In this case, issuance of the certificate shall be based on the provision of an equivalent document, issued by the third country. A personal ownership certificate is valid for up to three years.
