Enter the magical aquatic world of Blue Planet II

Despite having only aired three of its intended seven episodes, already Blue Planet II is receiving international acclaim for its incredible cinematography, breath-taking scope and unflinching look at the world’s oceans and all of its inhabitants.

Presented by Sir David Attenborough and produced by BBC Earth, the popular nature series follows the first instalment, released in 2001, and with more than 15 years having passed, technological advances mean the team can capture even more detail than ever before.

So far, episodes have explored animal behaviours uncovered on the journey from the equator to the poles, as well as the undersea cities of tropical reefs and the mysteries of the deep. In total, the team spent 1500 days at sea on 123 different expeditions, clocking up over 1000 hours in submarines in order to get the footage.
