The Blue Planet

Open Ocean

Series 1 - Episode 3 Open Ocean



Predators and prey in the open oceans come under the scrutiny of David Attenborough. Marlin track down a shoal of sardines as a sei whale scoops up the leftovers, dolphins herd mackerel and attract the attention of a sailfish with the resonance of their sonar, and giant sunfish queue up to allow other species, including seagulls, to feed on their parasites.
