The wonderful world of whales and dolphins. Below the waves lies a world of giants. Out in the open ocean, whales and dolphins are well-suited for to a life of wandering, traversing thousands of miles each year in search of krill blooms or breeding grounds. Together, these colossal mammals belong to the infraorder cetaceans. A name with roots in Greek, from ketos, meaning ‘a large sea creature’. But despite their size, cetaceans are elusive creatures, spending most of their lives underwater and in remote areas far out to sea. Let’s shine a light on the wonderful world of these marine mammals.

I read this as "Crustaceans : The Giants of the Open Ocean" and was absolutely terrified at the idea of a massive crab

This is a quality documentary. Short but long enough to keep the watcher interested, Well narrated, very pleasant voice from a talented commentator.

“This behavior is not instinctual” So some whale YEARS ago thought; I have an idea.... and that is just so fucking cool to me.

I had gone on a whale watching trip years ago, we saw a pod of 12 blue whales including babies. It was astonishing and everyone including the crew were amazed since they never seen more than 1 or 2 at a time. They had been in business for more than 30 years and it became a record. I will never forget how beautifully large they were, blowing water so high and gliding by our boat.

Cetaceans are such a diverse and interesting group of mammals. Not only do they reside in the sea, seemingly everywhere life is found, but they’ve specialized into niche roles like deep sea divers, massive filter feeders, or even intelligent hunters. Another thing astonishing about this group is their intelligence, they can learn, adapt, remember, teach, and plan. They’re not just robotic machines, but dynamic and cognitively active creatures that makes me respect the ocean even more than I already do.

It's crazy to think that some Humpback in history invented bubble net feeding, or at least pioneered it.

I have thalassaphobia, or the fear of open water. While these videos still give me the willies seeing all those creatures in such a vast space, I enjoy your informative and high quality videos!

I don't know what it is about whales, orcas and dolphins that I adore so much but just watching footage of them makes me feel like crying. They're such amazing creatures and I can hardly wrap my head around the fact that we exist in the same world as them. They're so fascinating and intelligent they almost don't seem real. It's a dream of mine to one day be able to swim or sail alongside some.

I needed this. There’s only a few channels that are perfect for that hour or two before bed that helps me drift away. I’ve burned up hours of content so I’m always trying to find that next awesome channel with replay ability. As amazing as the visuals are I can easily close my eyes and just listen and still be entertained and soothed. This channel is about to explode I think and I’ll do my part to help.
