Genetics
The mitotic karyotypes of both the female and male Koh Tao caecilians have 21 pairs of chromosomes, although in a study performed by Nussbaum and Treisman, it was found that there was an inconsistent report of chromosomes. While they all may have the 21 chromosome pairs, there was a study that found they have 18 metacentric, 4 submetacentric, and 20 telocentric chromosomes while another study had found 16 metacentric, 6 submetacentric, and 20 telocentric chromosomes in the caecilians. The conclusion that Ichthyophis genus is a karyologically conserved taxa when it comes to looking at the chromosome numbers.
