Cetaceans show remarkable diversity in diving capability, implying a range of adaptive strategies to hazards such as hydrostatic pressure and oxidative stress, but few studies have considered the evolution of extreme diving. Here, we first examined the relationship between morphological and physiological factors and diving capability and then considered the molecular evolution of candidate deep‐sea diving traits in a genomic d...

Beaked whales have recently been reported in the South China Sea but with taxonomic uncertainty due to their ambiguous morphological features. Here, we sequenced three genetic markers, the control region (CR) and cytochrome b ( cytb ) of the mitochondrial genome and the first intron of the nuclear muscle actin gene ACTA2 , of two biopsy samples collected in 2021, and revealed unambiguous clustering with sequences previously at...

The electric catfish ( Malapterurus electricus ), belonging to the family Malapteruridae, order Siluriformes (Actinopterygii: Ostariophysi), is one of the six branches that has independently evolved electrical organs. We assembled a 796.75 Mb M. electricus genome and anchored 88.72% sequences into 28 chromosomes. Gene family analysis revealed 295 expanded gene families that were enriched on functions related to glutamate recep...
