Figure 1 



Neighbor-joining tree showing relationship of observed 12s-16s haplotypes among 36 species of shark. Codes are defined 

 in Table 1 and numbers in parentheses indicate the number of individuals found with the indicated haplotype. Bootstrap 

 support is indicated as numbers immediately above the relevant node (only values greater than 70% are shown). The 

 phylogeny was rooted with several outgroup taxa (Heterodontus francisci (NC003137), Raja radiala (AF106038), Chunaera 

 monstrosa (AJ310140), and Rhinobatis lentiginosus (AY830717)).
