A cold advantage
Fucus distichus can tolerate freezing, and exposure to air, which gives it a great advantage during cold Arctic weather.
A sturdy structure
Fucus distichus contains a holdfast, which is a root-like structure that allows it to attach to a rock and protect itself from severe waves. This also creates a comfortable habitat where smaller organisms can shelter themselves from severe weather and larger predators.
Protection from the sun
Fucus distichus contains tannins (binding compounds of organic matter), which protect it from the sun’s ultraviolet radiation. These tannins could one day come in handy as ultraviolet light levels change across the Arctic.
