“…e . edeni , was increased by including new sequences from stranded whales in Bali, Indonesia in the eastern Indian Ocean (Yusmalinda et al, 2017) and the South China Sea (Li et al, 2019). Because the published sequences available in GenBank are of varying lengths, we performed the phylogenetic analysis on three different control region alignments: a 305 bp alignment that allowed us to include the broadest geographic coverage of the Bryde's whale complex contained 73 haplotypes, a 375 bp alignment containing 22 haplotypes and finally a 721 bp alignment containing 11 haplotypes.…”

“…The additional published sequences expanded the geographic range of the original phylogenetic analysis to include localities of Bryde's whales, B. e. brydei, in the southern Caribbean (Luksenburg et al, 2015), the East China Sea (Kim et al, 2018), the California coast of the eastern North Pacific, 1 off the coast of Chile in the eastern South Pacific (Pastene et al, 2015) and the coast of Brazil in the western South Atlantic (Pastene et al, 2015). The geographic range of Eden's whale, B. e. edeni, was increased by including new sequences from stranded whales in Bali, Indonesia in the eastern Indian Ocean (Yusmalinda et al, 2017) and the South China Sea (Li et al, 2019). Because the published sequences available in GenBank are of varying lengths, we performed the phylogenetic analysis on three different control region alignments: a 305 bp alignment that allowed us to include the broadest geographic coverage of the Bryde's whale complex contained 73 haplotypes, a 375 bp alignment containing 22 haplotypes and finally a 721 bp alignment containing 11 haplotypes.…”

“…Balaenoptera edeni Anderson, 1879 was first described from a medium-sized balaenopterid whale that stranded in Myanmar in 1871 (Anderson, 1878(Anderson, [1879). They are thought to inhabit coastal waters of the Indian Ocean and the western Pacific, with genetically confirmed records from the East and South China seas and coastal waters throughout the northern Indian Ocean from Oman east to Indonesia (Jayasankar et al, 2009;Kershaw et al, 2013;Kim et al, 2018;Li et al, 2019;Rosel & Wilcox, 2014;Sasaki et al, 2006;Wada et al, 2003;Yoshida & Kato, 1999;Yusmalinda et al, 2017). To date there are no records from the Atlantic basin or the eastern Pacific.…”

Bryde's-like whales are a complex of medium-sized baleen whales that occur in tropical waters of all three major ocean basins. Currently, a single species of Bryde's whale, Balaenoptera edeni Anderson, 1879, is recognized, with two subspecies, Eden's whale, B. edeni edeni and Bryde's whale, B. edeni brydei (Olsen, 1913), although some authors have recognized these as separate species. Recently, a new, evolutionarily divergent lineage of Bryde's-like whale was identified based on genetic data and was found to be restricted primarily to the northern Gulf of Mexico (GOMx). Here, we provide the first morphological examination of a complete skull from these whales and identify diagnostic characters that distinguish it from the other medium-sized baleen whale taxa. In addition, we have increased the number of genetic samples of these Bryde's-like whales in the GOMx from 23 to 36 individuals, all of which matched the GOMx lineage.A review of Bryde's-like whale records in the Caribbean and greater Atlantic supports an isolated distribution for this unique lineage, augmenting the genetic and morphological body of evidence supporting the existence of an undescribed species of Balaenoptera from the Gulf of Mexico.

“…BLAST is an efficient method of determining similarities and dissimilarities of sequences that are available in an online database and can be used to confirm species when morphological appearances are not useful [39,40]. The percent identity of the D-loop sample from our unknown whale agreed with data from the cranium morphology, as it had a high value of similarity to the D-loop sequence of B. acutorostrata but not B. omurai.…”

First Stranding Event of a Common Minke Whale (Balaenoptera acutorostrata Lacépède, 1804) Reported in the Gulf of Thailand

et al. 2023

On 5 September 2022, a dead baleen whale was found stranded at Laem Phak Bia, Phetchaburi, the Gulf of Thailand, Thailand but could not be identified because it was in an advanced stage of decomposition. It was first suspected to be Omura’s whale (Balaenoptera Omurai), as that is a common species in the Gulf of Thailand. However, the cranium morphology was different from B. omurai and more similar to the common minke whale (Balaenoptera acutorostrata) from the North Pacific Ocean, which has never been reported in Thai territorial waters. The mitochondrial DNA control region (D-loop) was then used to identify the species through the Basic Local Alignment Search Tool (BLAST) available at the National Center for Biotechnology Information (NCBI) GenBank, which resulted in a high percent identity, 96.49 to 98.84, with B. acutorostrata. A Bayesian phylogenetic tree was further used to confirm the species, which grouped with B. acutorostrata from the North Pacific Ocean. This study provides evidence of the first stranding event of B. acutorostrata in the Gulf of Thailand. It is new information that extends previous knowledge on the distribution of the common minke whale and raises the need for more active surveys of cetaceans in the South China Sea going forward.

“…Although the whales' movements, including diving, were clearly synchronized during the tracking period, it was unknown if they were cooperatively foraging. Chen et al (2019) reported on a feeding aggregation of Bryde's whales near Weizhou Island, northern Beibu Gulf, southern China, which was subsequently genetically identified as Eden's whales (Li et al, 2019). Although Eden's whales occur year-round in Beibu Gulf, their numbers increase near Weizhou Island during January-April (Chen et al, 2019).…”
