I am currently reading and watching Blue Planet II, the newest stunning natural history documentary Narrated by David Attenborough with the accompanying book which is authored by James Honeyborne andMark Brownlow. This programme has been made possible by using cutting-edge breakthroughs in science and technology to explore new worlds, and reveal astonishing creatures and extraordinary new animal behaviors not seen before, Breakthroughs in technology such as rebreathers and deep sea submersibles have enabled us to access areas which were previously out-of-bounds and enhanced our knowledge of the oceans, and our understanding of what goes on in them has been increased accordingly.
Blue Planet II Explores many different marine environments. The first episode includes Giant Travelly’s launching themselves out of the water to catch newly fledged Sooty Terns and Dolphins and False Killer Whales hunting together and cooperating in order to catch more food. The episode “deep seas” looks at the little known region at the bottom of the ocean where there is perpetual darkness. Despite this many bizarre looking crustaceans and fish manage to live here, with many providing their own light by means of bioluminescence while Six gilled sharks and primative Hag Fish feed on the carcasses of dead whales which have floated down from the surface. Deep sea vents exude toxic fumes and look uninhabitable, but despite this they are also home to a surprisingly wide variety of bizarre crustaceans and fish which are not found anywhere else on the planet.
The episode “coral reef” looks at the extensive communities which inhabit these areas including a wide variety of colourful fish, molluscs, crustaceans and sharks. However these areas are fragile and are under increasing threat from warming seas caused by pollution and gasses which are heating up the atmosphere and seas and causing ecolgical damage including coral bleaching. The next episode “open ocean” looks at Whales, Dolphins, sharks, Sunfish and and other marine animals which spend their lives patrolling and feeding in the open ocean”
The next episode “green seas” examines the many inhabitants which live among Sargassum Seaweed including Sea Lions. The next episode is “coastal regions” which examines sheer cliffs and rock pools which are inhabited by a wide variety of crustaceans, molluscs, jellyfish, fish, and large communities of nesting birds including guillimots, Puffins and Terns, gulls whose young are preyed upon by predatory Frigate Birds and Arctic Skuas.
The final episode “Our Blue Planet” looks at the impact human activity has had on the ocean from Acidification and coral bleaching caused by warming seas, pollution, over fishing, killing sharks and littering of the planets oceans which has had a disastrous affect on some species but has allowed species like predatory Humboldt squid to benefit.
