Figure 10. Maximum-likelihood tree of Weddell Sea gromiids (shaded boxes), Arabian Sea gromiids (Aranda da Silva et al., 2006), and Gromia oviformis from shallow-water localities (Burki et al., 2002), based on partial small subunit ribosomal DNA (SSU rDNA) sequences. The numbers at the nodes represent the percentage of bootstrap support,> 50%. Weddell Sea gromiids are grouped into three distinct clades (A, B, and C).
