How do penguins avoid predators in the ocean?

Penguins avoid predators in the ocean by using their speed, agility, and group behaviours. They can swim up to 22 miles per hour, outmanoeuvring many predators like seals and sharks. Penguins also use countershading, with their dark backs blending into the ocean depths and their white bellies camouflaging against the bright surface. In addition, they often swim in groups, creating confusion for predators and improving their chances of survival. These adaptations make penguins formidable in their aquatic environment.
