Haplotype network of cox1 sequences for Tylodelphys clavata. Circle size is proportional to the frequency of each haplotype. Perch populations from different lakes are represented by different colours. The haplotypes that include NCBI sequences are highlighted with a star; neyes refers to the number of eye samples; nsequences refers to the number of sequences from the NCBI database. The insert histograms illustrate the number of haplotypes observed per eye and the frequency of haplotypes
