You've heard of the king cobra, right? But wait, it's not just one species—there are actually four king cobra species, as per. a new study. The research, led by biologist P. Gowri Shankar, shows genetic and morphological differences across king cobras from India to Southeast Asia. The four species are O. hannah, O. bungarus, O. kaalinga, and O. salvatana. The study also highlights the need for species-specific antivenoms, as current treatments may not be effective across all king cobra species.
