Relation to Humans
Whole genome mitochondrial sequences were analyzed from the X. fraseri type specimen and several other Xenopus specimens using Maximum Likelihood and Bayesian methods. The study found that this species is the sister taxa to X. fischbergi and is firmly within the X. muelleri species complex, which also includes X. borealis. Xenopus fraseri appears to be more recently diverged and may have resulted from an allotetraploid event. This relationship is supported by morphological comparisons (Evans et al.2019).
This species name is in honor of Louis Fraser, the researcher who collected the first specimens of in 1852 (Boulenger 1905, Evans et al. 2019).
