The fish shown above is the anglerfish. the stalk in front of its eyes is a flashing light that it uses to lure prey near its mouth. this is because the biome that it lives in is very dark. where are anglerfish likely to be found? a) an estuary b) a freshwater lake c) the abyssal zone of the ocean d) the pelagic zone of the ocean

The right option is; C) the abyssal zone of the ocean

The anglerfish are likely to be found in the abyssal zone of the ocean.  

The abyssal zone is the bottomless layer of the pelagic zone of the ocean that has the bathyal zone located on it.  The abyssal zone is at depths of 4,000 to 6,000 metres, and it remains permanently in darkness. This zone is a food limited environment because it lacks nutrients. The temperature of the zone is around 2 to 3 °C and has continuous cold.
