@rav_af: Viperfish (Chauliodus) are ferocious deep-sea predators known for their oversized, needle-like teeth—which are too long to fit in their mouths and curve back to their eyes. These 12–30 cm fish hunt in the, "twilight zone" (up to 1,500m deep), using a bioluminescent dorsal fin to lure prey and a hinged,, "hidden" lower jaw to swallow creatures up to 50% larger than themselves. #Nature #ocean #Viper #fish #creepy
