Next up for animal phyla is Cnidaria! This phylum contains jellyfish, sea anemones, corals, and all kinds of other organisms. This one is pretty meaty so it will take several tutorials. Let's start by getting through some information that pertains broadly to the entire phylum!

That is fascinating. I never thought I’d be honored to have been stung by a jellyfish.

@kennethkossan5547 2 года назад

I became a fan of yours, as I think a lot of people did, when you were dealing with the flat earth crowd. I have been pleasantly surprised at your ability to communicate science topics with such deftness. This series is wonderful. It’s so great to hear you pronounce these words so precisely and with such ease. It really does communicate a mastery of the subject matter which gives me confidence that you are supremely qualified. Thanks again.

@CrochetIsLife54 2 года назад

I find Cnidaria fascinating. In the long haul between single cell organisms (which are incredible in themselves) to the post-Cambrian world, animals had to evolve muscles and nerves, and Cnidaria have both. Some even have rudimentary sight. I suspect that, at one point in Earth’s development, Cnidaria were the apex predators. They don’t have the fan club of the T-Rex, but some of us like them a lot.

@uprightape100 2 года назад

Whilst Cnidarian fossils "only" go back 580my, cladistics place the development of their cnidocyte stinging cells much further back, closer to 700my, in creatures not unlike the modern Hydra that are too tiny and squishy bodied to fossilize. By the Ediacaran, Cnidarians had already diversified into myriad forms.

@HardToBeAPoopGod 2 года назад

I hope this hasn't been asked ad nauseam already, but *what's the key difference between symbiosis and mutualism?* I never quite got a straight answer on that, so maybe you're the right guy!

@brittanyjacobson5199 2 года назад

Mutualism is one type of symbiosis. The other types are commensalism and parasitism. Commensalism is when one organism is benefited and the other is not effected. The examples often given are cattle egret eating bugs scattered by cattle and barnacles hitching a ride on a whale.

Hey Professor Dave, currently I'm watching your "Learn math start to finish" playlist, I took Calc 2 last semester and dropped, I was having difficulty with even the simplest things, but I feel so much more confident after watching some of your videos, even though I haven't gotten to far into the course. Turns out I didn't even have a strong grasp of Algebra, I feel like for the first time ever I actually somewhat understand math. I always wanted to be good with my left brain, physics math and computer science just the analytics, now I don't think I'll be able to conquer the world of physics, but Cs I feel is something I might be able to get a grasp on, were you ever planning on making a playlist on CS or programming to be more precise.

@ProfessorDaveExplains 2 года назад

Yes I will get to that! I have to do all areas of engineering first, then computer science, then coding/programming, so it will take me several years to get through all of that.

@qlex26 2 года назад

When I see the name cindaria, i think of a similar (non-real) creature in a game called ARK: Survival Evolved. The base game has different dinosaurs and prehistoric animals from different times, that are biologically and functionally changed (some changes are high, while some are small), so they don't actually exist. They are super electric and can destroy a lot of things if you don't pay attention to them. Well, it's s survival-type game that evolves into fighting massive monsters in the end, which is awesome. There's loads of lore and such. I suggest checking it out.

Hello professor Dave, not related to this video, but do you maybe know of the experiment a guy made I then hundert years ago or so maybe 80 ago, he measured the earth curve on a beetch with a physical divice he engendered, like a 2 or 3 Meter long construction with a very accurate steel plate he connected many of those, i thought this is so interesting and such great craftsmanship, but I can't find it no matter how I search for it

Quick question what are the Vanallen bets ? What material did we use to get through them and finnaly how did we Achieve escape velocity with all that extra mass on board . Thank you for your time and consideration. E Z that's M E . he he

@ProfessorDaveExplains 2 года назад

There's nothing to "get through". It's just radiation. We also don't need to achieve escape velocity. That's for projectiles, not rockets with boosters continually firing.

@Tornadopelt 2 года назад

The Van Allen Belts are not a material; they're radiation belts, primarily alpha and beta particles. Alpha particles are helium-4 nuclei with no electrons; beta particles are high-speed electrons that were ejected from the nucleus of some radionuclide. Both of these are charged particles, which means that technology where a single stray electron can mess up the entire system, namely *modern, digital* technology, has to be extensively shielded via some sort of Faraday cage so as to protect the technology onboard. Older technology, such as the magnetic-loop computers in the Saturn V, were vastly more resistant, but were also larger and far less powerful than today's tech.

Fun fact: a study from 2007 (DOI: 10.1007/s00427-007-0165-0) has shown, that Hydra magnapapillata apparently has an aboral pore, that is maintained by a constant degredation of the extracellular matrix and is present independent on the form of reproduction. Would be interesting if that pore could be confirmed in other polyps as well
