Data from: Ancient and recent hybridization in the Oreochromis cichlid fishes
<p>Cichlid fishes of the genus <em>Oreochromis</em> (tilapia) are among the most important fish for inland capture fisheries and global aquaculture. Deliberate introductions of non-native species for fisheries improvement and accidental escapees from farms have resulted in admixture with indigenous species. Such hybridization may be detrimental to native biodiversity, potentially leading to genomic homogenization of populations and the loss of important genetic material associated with local adaptation. By contrast, introgression may fuel diversification when combined with ecological opportunity, by supplying novel genetic combinations. To date, the role of introgression in the evolutionary history of tilapia has not been explored. Here we studied both ancient and recent hybridization in tilapia, using whole genome resequencing of 575 individuals from 23 species. We focused on Tanzania, a natural hotspot of tilapia diversity, and a country where hybridization between exotic and native species in the natural environment has been previously reported. We reconstruct the first genome-scale phylogeny of the genus and reveal prevalent ancient gene flow across the Oreochromis phylogeny. This has likely resulted in hybrid speciation of one species, <em>O. chungruruensis</em>. We identify multiple cases of recent hybridization between native and introduced species in the wild, linked to the use of non-native species in both capture fisheries improvement and aquaculture. This has potential implications for both conservation of wild populations and the development of the global tilapia aquaculture industry.</p>

Fig. 1 in Short communication Antecedent description and depiction of the recently described cetacean behaviour of trap/tread-water feeding inferred from a nineteenth-century sighting of a 'sea monster' in the Gulf of Suez, Egypt
Fig. 1 - Illustration of a nineteenth-century encounter with a purported sea monster observed in the Gulf of Suez (Andrews, 1879). The vertical body position and open mouth of what is obviously a baleen whale (the rightward animal in the group) closely resembles the photographs and digital reconstructions of the recently described, so-called 'new' or 'first' descriptions of the stationary hunting behaviour of trap/tread-water feeding, as shown in Iwata et al. (2017), McMillan et al. (2018), McCarthy et al. (2023a, 2023b), and Lu (2023). The illustration, drawn in concordance to the eyewitness report, is emblematic of the instance of such whales 'rapidly closing them [their mouths] to trap prey' (McCarthy et al., 2023a). Note the presence of seabirds, something common to all modern recorded instances of such feeding documented in humpback whales, an association which may be related to shoaling fish being driven to seek the apparent shelter of the whale's open mouth (McMillan et al., 2018).
