Blackfish are remarkable. They are amazingly hardy, capable of living without oxygen for a day and without food for a whole year. They can withstand a temperature of -20 degrees Celsius for 3/4 of an hour because of a special type of antifreeze in their blood that lowers their freezing temperature. They are a type of mudminnow, meaning they live in low-lying mossy ponds with soft bottoms. These fish are dark brown and black colored with dark speckles and are about 30 centimeters long. Blackfish feed mainly on crustaceans, but also on insects and worms.
