Cetaceans, the Giants of the Open Ocean

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

[nettiespitfire]

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

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.

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

[nomethodonlymadness]

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!

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.

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.

[c_frce]

No idea why this was recommended but Jesus dude the effort you put into this is amazing.

[beedubree]

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.

[asliceofloaf]

It's very rare to find a channel that talks so passionately about their content. I'm really glad I found you and your videos.

[_lime.]

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

[dutchboy]

This has to be the most professional but underrated channel on YouTube

[Herio]

Found by accident, subbed immediately such quality content should be on the main page of youtube.

[GentlyPeaceful]

To anyone who's suffering depression, anxiety, insomnia and other mental health problems, you are not alone. I feel you. You are so brave. You are doing so well. I'm proud of you. I'm sending you a virtual hug

[wristocrat]

Absolutely amazing documentary. I was in a mild depression today and this cured it by showing me how beautiful the world is. Your narration is excellent, you’re speaking every word with perfect execution and not making it sound robotic. ✅✅

[firewaters]

I agree with people on the comment section... the content and the quality is “SUPER” 👍🏽

[skato]

I'm so glad I found this channel. As a child and teen, when watching TV it would always be on Animal Planet. I don't have cable anymore and this is FREE. Top notch editing and very informative.

[joeydr]

This has got to be the best small Chanel on YouTube

[tristanmeyer]

This is honestly one of the most well-produced and written nature channels on Youtube. Keep up the phenomenal work. P.S. I love your videos.

[livin]

This channel….the clips, the facts, the voice of the narrator…it works perfectly.
