It’s Fun to Know: Fish Hibernation

It turns out bears, squirrels, and other woodland creatures aren’t the only animals to sleep through the winter. Marine biologists have discovered that Antarctic cod hibernate too. The cod reduce eating to about once a week, slow their heart rates, and settle down on the ocean floor during the coldest part of the year. Researchers believe this allows the fish to survive the region’s dark winters, when it’s hard for them to find food.
