Sea Stars | JONATHAN BIRD'S BLUE WORLD

At first glance, starfish, more properly called sea stars, aren't doing much of anything. But Jonathan's investigations reveal a slow-motion predator that hunts and attacks its prey. Traveling the world, Jonathan investigates sea stars from the tropics to the Antarctic and uses time-lapse photography to reveal an amazing complexity to the world of the sea star.

You might not think of sea stars as being very intelligent, and you’d be right, but you might be impressed by some of the amazing things they can do, especially considering they don’t have a brain!
Starfish, more correctly called sea stars, live just about everywhere in the ocean, from the tropics, to Antarctica and everywhere in between. They come in all shapes and sizes from fat and stubby… to long and skinny.
This brittle star walks with a coordinated effort using its rays like legs.
But most sea stars get around using hundreds or thousands of tiny tube feet on their underside. This is a Northern Sea star, living in the coastal waters of New England, and it’s a predator.
It’s hunting a scallop. It’s a drama played out in slow motion as the sea star moves in for a grip on the scallop’s shell.
But the scallop is not defenseless. With a mighty blast of water, the scallop jets away to safety.
So the sea star wraps itself around a mussel. Mussels are attached to the bottom and can’t get away.
The sea star uses it’s strong tube feet with suction cups to pull the mussel open a tiny bit, and digests its victim by injecting its stomach inside the mussel.
Picking up the sea star, I can see that it has the mussel firmly in its grip.
But not all sea stars feed on mussels and scallops. A Basket star feeds on plankton in the water. It has finely branched arms that act like a net, to catch the tiny bits of food floating by. It positions itself to be able to grab as much plankton as possible in the current.
Exploring a reef in the tropical Pacific, I find a Crown-of-thorns sea star dining on the coral.
This thorny, armored sea star is one of only a few animals that can digest living coral. It wraps itself around a coral colony and eats the polyps, leaving a dead, bleached coral skeleton behind.
Here’s a healthy colony of plate coral. And here’s one that has been eaten by a crown-of-thorns. Outbreaks of these sea stars have been known to kill entire reefs.
Carefully picking one up to avoid the sharp and venomous spines, I can see the stomach, which the sea star inverts out of its mouth to digest the coral outside of its body.
These sea stars are the second largest in the world, growing bigger than a dinner plate. But if you think these are big, wait until you see the largest sea star in the world!
To find it, I've come all the way to British Columbia. I'm looking for the Giant Sun Star, and you won't believe the size of this thing!
In the cold, murky waters of the Canadian north Pacific, I swim through beautiful gardens of sponges, anemones and soft coral, searching for a Giant Sun star.
And then, down on the bottom, I find what I’m looking for. It has up to 24 arms, more properly called rays and reaches 3 feet across. This is the world’s largest sea star!
Compared to most sea stars, the Giant Sun Star is a speed demon, cruising along the bottom in search of its favorite food-other sea stars and the occasional sea cucumber!
Here, a sea cucumber makes an emergency retreat to escape this hungry Sun Star on the move!
A thousand miles south on a reef in the tropics, I find a blue Linckia sea star on the bottom. Like the vast majority of sea stars, this one has only 5 rays.
With tiny tube feet on its underside, this sea star barely seems to move, but when I speed things up with time lapse photography, Linckia sea stars appear very active, moving about and grazing the bottom for food.
But even more curiously, they are polite, restraining from walking on top of each other. Like bumper cars, when one Linckia touches another, they each go the other direction. It’s all very civilized.
In an hour, a Linckia on the move can travel several car lengths.

The blue sea star look like they're made out of clay lol so cute

I'm from BC and have only been diving a few times. Been lucky enough to see a lot of flora and fauna though! I've been watching a lot of your videos recently and your passion has really inspired me in terms of diving and otherwise. Thank you!

Back ground music is superb it gives some feeling to see the star fish visually 🐠🐠🐠

[@mister.quack.6527]

Is nobody gonna talk about the sea star on the head of Jonathan in the beginning?

[@JDoe001]

Ha! Ha! I’ll bet it was thinking like the falling whale in The Hitchhiker’s Guide to the Galaxy “Ah … ! What’s happening? it thought. Er, excuse me, who am I? Hello? Why am I here? What’s my purpose in life? What do I mean by who am I?”

[@dat1dude688]

3:28 patrick, since when where you called the crown of thorns sea star? And can you stop eating the coral?

[@katiejackson1203]

It's painful how slow the sea cucumber was😂

[@apdroidgeek1737]

To be fair both the starfish and the sea cucumber are slow...

[@notaspacefan3350]

Interesting facts about Sea Stars and their natural habitat.

[@keanethepro2931]

[@JDoe001]

OMGOSH! So fascinating❤️

[@jonathansantos6691]

Its amazing how you found a brittle star walking around during broad daylight. That sea cucumber was so lucky intuitive in escape performance coverage. What a generous luck separated? Yes, those bluish linkys are fun related. I mentioned about a personal story with one of them. In my other comments of another video. Thanks for such videos. It shows and tells us so much more we get to wonder about. 🐙

[@batmeister]

3:03 galactus of the sea and I bet the sea cucumber was like oh sunstar your aproching me not walking away but coming tourds me

[@moalzaben5554]

Sea stars are such effective hunters and voracious carnivores. They are effective because their tiny tube feet have small suction mechanisms that can build enough pressure to tear open an urchin shell to suck the nice juicy insides which is the Bat star’s favorite food

[@user-mh2bw4hu3o]

7:35 Is that a magenta/pink starfish ontop of a yellow sponge?!

[@TaurusToyVideos]

Yes

[@apdroidgeek1737]

A day in a sea stars life: Find scallop, get grip on it, too slow, it sneezes and fly's away, look for another one, etc, until you get one

Beautiful, Mr. Bird, sir,

[@ningyosekai]

Oh wow I thought sun stars were everywhere! I didn't know they specifically live in my area

[@jonathansantos6009]

I remember when I was on the island of Guam I found blue sea stars on the beach and I pick one up and felt it and look on all side of it and when I was contented with it I threw it like a ninja star in a way that it had the most amazing fun as it spun and floated through the air and back into the water. I still wonder if it had learned from that moment and created more babies of its kind. I appreciate your time you take to edit your videos and say good things we all need to hear and experience. Presentation shows the time away from the water too.... Thank you so much. Your my favorite diving guy I know of.

[@TheNerdCorporation]

Sea stars do not have brains :/ so it cannot think/feel according to science, otherwise your idea was a fun one 😅

I bet both, because all are wild and some are able to defend or attack. . . so a knowledge is prob best to not be scared, but fascibated
