Is a viper fish rare endangered or extinct?

The viperfish (Chauliodus sloani) is not classified as rare, endangered, or extinct. It is considered to be relatively common in deep ocean environments, particularly in tropical and subtropical waters. However, its deep-sea habitat makes it less frequently encountered by humans, which can lead to misconceptions about its rarity. Conservation status assessments can vary, but as of now, the viperfish is not listed as threatened.
