Axial duplications are the most complex variant of anomalies characteristic of animals, including turtles. For turtles, the following variants of duplications are described: anakatamesodimus, derodimus, dicephaly, Siamese twins. We present a description of two specimens of the Mediterranean tortoise (Testudo graeca Linnaeus, 1758): with dicephaly and ischio-omphalopagia, a variant of Siamese twins, in which lateral fusion occurs in the region of the sacrum.
