Delphinoidea is the largest group of toothed whales, including 66 genera in 6 families. The largest living member of the superfamily is the orca, which can reach 6 tons, while the smallest is the vaquita.

Taxonomy

“The Delphinoidea has a diverse taxonomy, with over 35 mammalian taxa. This includes the species of genus Odobenocetops and Odobenus rosmarus [2] . While also having two types of genus, they also have individual genomes with about 9 species across the three main families of the Delphinoidea. The three main families of the whale are the Delphinidae, Monodontidae and  Phocoenidae. [3]
