Meet the Atlantic Wolffish!
Just like the name implies, they are key predators of the sea. These fish have evolved to live in freezing water as low as zero degrees celsius. They can also live up to 20 years!
The Wolffish have fang-like teeth that are ideal for crushing sea shells and eating oysters whole. These creatures live deep in the depths of the Atlantic Ocean.
Even though they may look threatening, they play an important role in the ocean’s ecosystem. They help control sea urchins from overpopulating.
So, no need to be afraid of the big, bad wolf.
