Episode 4 – Fish

Preview

Fish can fly, sense electricity, swim at over 100mph and even walk on land. From the open ocean to coral reef and storm-ravaged surf, to the freshwater springs of Kenya, swim with sharks, mudskippers and convict fish. Hunt with sailfish, glide with flying fish, enter the secret world of courting sea-dragons and even join the epic journey of the tiny, cliff-climbing gobies.
