Anglerfish

Anglerfish is widely considered as one of the most bizarre deep sea inhabitants. Most who have seen it find it the ugliest creature on planet. But despite its looks, it is an incredible example of adaptation and survival in most extreme environment. Named after its pray luring method, anglerfish usually lives a mile below the surface where the water is freezing and light is scarce. Ranging in color from dark gray to dark brown, these carnivores have huge heads with enormous crescent-shaped mouth filled with long, fangs-like teeth angled inward for efficient pray grabbing. Their length can vary from 8 in (20 cm) to over 3 ft (1 m) with weight of up to 100 pounds (50 kg). Most recognizable feature of an anglerfish is a distinctive spine resembling a fishing pole sprouting from the middle of its head, possessed only by female specimens. It is used to lure pray close enough to be captured and eaten by jaws snapping shut when contact with the spine is made. Anglerfish’s skin and bones are very thin and flexible. The skin can be peeled of with a mere touch of a human hand. However, this allows them swallowing pray twice their own size, which is crucial as food is always scarce in deep sea waters.
