What type of habitat does a viper fish live in?

Viperfish inhabit the deep sea, specifically in the bathypelagic zone, which ranges from about 1,000 to 4,000 meters (3,280 to 13,123 feet) below the surface. This habitat is characterized by extreme pressure, darkness, and cold temperatures. Viperfish are known for their bioluminescent features, which they use to attract prey in the pitch-black depths of the ocean.
