Extreme worms: Specialized seafloor polychaetes 

We created this video in celebration of the second annual International Polychaete Day (July 1, 2016). It highlights polychaete worms with special adaptations enabling them to survive in extreme environments on the deep seafloor, such as decaying whale skeletons and hydrothermal vents. Some of these worms can tolerate water temperatures up to 176 degrees Fahrenheit!
