Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. E. Rosel et al. 2021 | Balaenoptera ricei differs from B. e. edeni and B. e. brydei in the following morphological features: the nasals taper and curve laterally at the posterior end and have a smooth margin, meeting the medial-posterior margin of the ascending process of the maxilla; there is a broad gap between the nasal bones that does not narrow posteriorly created in part by the frontal bones which protrude anteriorly between the posterior end of the nasals (Figure 8). Rice's whale can also be differentiated from all other species of rorqual baleen whales based on molecular genetic characters, as shown in the phylogenic analyses of the mtDNA control region (Table 3, Figure 2). Within the 305 base pair align- ment of the 50 end of the mtDNA control region, ten diagnostic sites differentiate B. ricei from both B. e. brydei and B. e. edeni (Table 2). |
