How Sea Spiders Breathe Without Lungs or Gills | ScienceTake

“A lot of strange creatures
live in the cold depths beneath the Antarctic
ice, but none stranger than the giant sea spiders. Sea spiders are often
tiny, but Antarctic species grow to dinner-plate size. Even stranger are
their internal organs. Their genitals and
parts of their guts are found in their legs. And because their
heart is too weak to pump hemolymph, the
equivalent of blood, around the body,
it’s the movement of the guts that do
most of the work. There are many questions
about these creatures, but one big one is how they
get oxygen into their bodies. Fish have gills, so
do crabs and lobsters. Water flows over them and
the gills absorb oxygen. Worms, in the sea and
on land, absorb oxygen through their skin. But the sea spider
has no gills or lungs, and its skin is an
exoskeleton, a bit thick for absorbing oxygen. What it does have are
hundreds of pores. They use this
respiration chamber to calculate how
much oxygen the sea spiders
were taking in. They found that
the countless pores in the spiders’ thick
skin acted, in effect, like breathing holes. The pores offer an easy
way for oxygen molecules in the seawater to be
absorbed by the body. To collect sea
spiders for research, scientists had to dive
beneath the Antarctic ice. Since the water
was so cold, diving requires serious preparation,
but the result is worth it.” “I was pretty petrified about
the cold and the ice ceiling before I started
diving there, but it’s kind of spoiled me
for anywhere else.” “Why devote all this
effort to sea spiders? Well, they’re kind
of irresistible. Everything they do is weird. And our planet’s
poles, north and south, are warming faster than
any other places on Earth. Learning how these
creatures live in these extreme conditions may help us understand
how they will cope with climate change to come.”

  2. I don't like snakes and 'm a little squeamish but I subscribed anyway.
    I hope it didn't break any rules.

  3. See that? That's why science tells you to wrap your willy. Or tiny lifeforms without even gills that look like that possibly could appear when you try to pee, at least under the microscope of clinical evaluations.

  4. i thought spiders are terrestrial organisms… are they real spiders or pseudo-spiders or true crustaceans or pseudo-crustaceans? they really look amazingly like real spiders trapped under frozen ice

  5. Thought this video looked interesting but unfortunately it was just another “climate change” propaganda clip in the end.

  6. Excuse me, we're 20 trillion in the hole…remember? It will be a couple hundred years before that water gets too warm for those things, assuming it ever does. Why do we even care anyway? More congressional pork, like studying why 2-yr-olds fall off tricycles.

  7. The sea spiders will do what they always do when the planet goes through its warming and cooling cycles like its always done.

  8. sea spiders? seriously we can't escape them! What's next? "space spiders" or something equally horrific?

  9. Big deal. Lots of living creatures breath through diffusion. And you don't have to drill through a continent in the middle of nowhere to study them. This is not news, in fact, it smells a lot like global warming crap. It is the NYT, after all..

  10. Plot Twist there's only around less than 700 Arctic Sea Spiders Left since their eggs mostly don't survive due to the environment conditions.

  11. Man these videos are well done.
    Glad the NY Times has adapted to the digital age well, unlike some newspapers

  12. Climate change lol. They will adapt or die, as animals and plants and humans always have. Enough with the fear mongering. Also, animals that CAN live in extremely harsh environments don't NEED extremely harsh environments to live. Polar Bears survive IN SPITE of the cold, not BECAUSE of the cold. They are bears. If it gets warmer,. they will not melt, they will just suddenly find it easier to find food.

  13. Why did the computer model have so many legs? It was standing on 12 legs while the arthropods in the clips did not seem to have more than 8 legs?

  14. Can you make a video about the kerguelen islands and the subcontinent that lies below it and it's ancient glaciers and creatures found on and around its volcanic soil. I would go myself but I don't own a boat and there's no airport. Thanks I love what you do.

  15. How has every living organism coped with "climate change" during the history of planet Earth?
    The climate has always changed, with or without human inputs.
    Some species adapt while others die off. One thing is for certain, planet Earth will be just fine, with or without human.

  16. Freezing, can't move at all
    Screaming, can't hear my call
    I am dying to live
    Cry out, I'm trapped under ice—Metallica

  17. Looks like operation "burn it with fire" is gonna work here. Time activate solar flare. We gon' vaporize this ocean!

  18. “they dont have lungs, gills and they cant breath through their skin”
    2 seconds later
    “They breathe through their skin”

  19. List of Spiders:
    Normal spiders
    Flying spiders
    Sea spiders
    River spiders
    Zombie spiders

    Next discovery:
    Space spiders
