- It's time to learn all about animals! And we aren't just talking about cats and dogs here, did you know that sea sponges and corals are also animals? It's a very diverse kingdom, that Animalia! It even includes us humans. So what defines an animal, and how do we categorize them? How many types of animals are there? Well in short, a lot, so strap in let's dig through the animal phyla one by one!

This video led me to hours of catch-up reading.
I'm 67. In school, I took all the 'advanced' or 'honors' classes in biology and zoology. My grades were good, as with any subject that interested me.
But there were then only three Kingdoms: plant, animal, and protist. The entire classification system has been rewritten.
Maybe a cautionary tale for young folks studying now. It's not cast in stone folks, and will always be subject to revision when new tools and information become available.
This is the best comment I've read in quite a while
Goddamn 67. You are one cool ass grandpa ngl
Omg love your vids 🤗
You’re complaining I’ve actually got a biology degree from the same time. Talk about catch up time .
@@STWD1ST I hope you know, some of us old farts went beyond high school.
I know this is cringy but I’m gonna be that weird kid here, I’m in middle schoole rn and want to better my education because one day I want to become a biologist and I just really wanna thank Dave for what he does, he makes learning stuff simple and fun and believe it or not your one of the only teachers I have actually enjoyed lol
Do not kill the part of you thats cringe, kill the part of you that cringes. Middle school already sucks, no need to bully yourself on top of it. Good luck on being a biologist, I've considered wildlife biology but I think I'll go into mathematics instead, simply because I can pay off the college debt.
Start with making a vocabulary list! I’m a college student and that’s what I do. There Gonna be a lot of words you don’t know and it can be overwhelming so while you learn make yourself a vocab list to get rid of that pesky anxiety that may come with learning. Hope you are well and still enriching your mind! -a fellow zoologist 😉
Why would it be cringy?
i’m also a middle schooler who really wants to go into biology!
same here bro
So exciting! I can tell this series is going to be AWESOME. I appreciate that you are mentioning obscure animals such as gastrotrichs, bryozoans, etc. I just love those obscure phyla. You did a good job explaining about the importance of common ancestry and DNA. Thanks for doing this series.
This zoology series is gonna be so interesting. Excellent work professor Dave. I appreciate your hard work.
I once had someone seriously ask me if yeast was an animal. I didn’t even know what angle to approach that from. Your angle is good.
Fun fact: Some members of phylum Loricifera also can live in oxygen-free environments. This is because they use hydrogenosomes instread of mitochondria.
Hydrogenosomes? More like "highly interesting!" Thanks for sharing that piece of information.
Very interesting, also, aphids are part of the very few animals that can preform photosynthesis
Dave has made it his mission to gather all of humanity's collective knowledge on one youtube channel.
Hooray! I have been looking forward to this series for a very long time. Thank you so much Dave. I really appreciate your channel. Keep up the good work.
Thank you a lot!!! You are a lifesaver! Because of your free classes which are also understandable, and far more away from any complexity, I can enrich my knowledge and be capable of understanding certain subject in another language which is not even second.
I accidentally got into zoology but now loving it. I know it doesn't pay much but it sure is an interesting field
how do you produce so many quality videos in so little time???
Writers and editers
He really does know about all the science stuff!
Been watcing these videos for a while now and it's about time to say thank you. Your videos are perfect - exactly the depth level that I need, well and clearly explained, even for a non-native speaker, just perfect! Thank you for doing this! It's been such a big help and will be even more with this series.
My favorite part was the shilly shally worm. I just love creatures that have photosynthetic symbionts.
Great series, do paleontology next if you haven’t already as those 2 Fields of science are the most interesting in my opinion. Anyways, keep up the great work, love the videos as always!!
Now this is my favorite branch of Biology, the study of animals.
You’ve single handedly been helping me thro my zoology degree
Hi I'm really thankful, appreciate you and your work. We're learning from you from Tajikistan so what I wanna say you have knowledge in so many field. Can you please make videos about How To Learn efficiently, online, how to become a better learner
Some amoebas actually are animals. Amoebas are not a monophyletic grouping and some of them are members of kingdom animalia. I'm going to love this series haha.
Awesome video professor 👏🏾
I'm currently stuck in a technical field and I want to be a zoologist. I really want to learn about animals.
I'm curious, and if I might ask, what field are you in?
This video is absolutely staggeringly amazing. Thank you.
RUclips: I think you'll like this video, it's titled "What are animals?"
Alright, listen here, you
Dave's a pretty smart guy
He just makes me love every subject he teaches 🌈🌈
Incidentally, I have met people that actually thought that the way that fish breathe is that the fish literally take the oxygen out of the water molecule itself. In other words some how the fish break the covalent bonds in water to get oxygen. I explained to them that actually the oxygen is just dissolved in the water.
🐟🐡🐠💥💧
@@cookieman2028 Now you've got me thinking of a hypothetical fish... one that applies electrolysis to get oxygen out of the water and--
[ZAP] *[BANG]*
...huh. So *that's* why we don't find exploding fish in the fossil record.
Awesome and amazing presentation of science as a whole as well as Zoology. What a great teacher you are. I didn't realize how much I enjoy science. Thanks for sharing.
Thank you so much Jebiosus
Thanks so much I’m so into animals been raised around animals my whole life
Thank you for including links to videos for review. Great work!
Gotta love the knotted dogs at 00:24 lol
wth 💀
il miglior prof❤️❤️
Finally!!!
Great zob professor
Are you trying to study each and every field that exists?
😂
Yessssssssss
Extremely ironic question, considering your screen name.
He just has writers write this shit up for him he dont study
@@billballinger5622 Yea,someone wrote the script,but that doesnt mean he hasnt studied what he is presenting. You just dont like him. Oh well.
@@johngavin1175 hes an unlikable guy. Not my
Fault
Great guy!
good one there
thank you so much 🥰🥰
Great 👍👍👍
Zoology? More like "Cool-ology", at least as explained by you!
How will we classify animals when we find them on other planets? Surely, they would not originate from the same animal that we all came from, and it may potentially be possible for them to also violate a few of those rules, maybe more consistently across an entire planet than ours.
From a biological perspective they would be their own categories!
Well "animals" or "plants" of other planets would be aliens and they would their own categories of lifeforms like when there would be life on a planet like PandoraIII it would be "Pandora-III-Multicellularkingdom-subunit96345" or maybe "P3-nimal" or so as shortcut.
Evolution isnt real. Archetypal form existed before the material
@@billballinger5622 Nope. This is a denial of genetical observations and independently we would find claimed archetypes in old burials. But we don't.
@@billballinger5622 Ahahahahahahahahahahahahahaha
everyone pray for me, I am a frehman psych student and we have this subject. As of now i'm really anxious and to mention that the professor is intimidating. (Pls i don't manifest any bad luck) 😔
Hey professor when will you make that video on dr Eric berg.
I understand that almost everyone does this as it is pretty common these days and not really a big deal, but, zō-ology (more like toe) instead of zoo-ology.
It just bothers me, like when people use homogenous (archaic biology term) instead of homogeneous (scientific term to describe uniform mixtures). Also, like how most people will completely butcher tinnitus.
Keep up the good work though, please don’t take this as hate on the video.
No its zoo-ology
@@billballinger5622 unfortunately, it isn’t. It’s zō-ˈä-lə-jē. Even when you reference the root word, it has a long ō sound.
Doesn’t mean people don’t pronounce it zoo-ology, that’s just the common usage because people see the two o’s, think oh zoo like the place that has animals, and use the zoo pronunciation. Ignoring that if it were zoo, it would have 3 o’s.
Please, don’t take my word for it, the Merriam-Webster website let’s you hear pronunciations of words.
On the other hand, Google translate will give the zoo-ology pronunciation, because it has become common everyday usage for the term.
For reference, the word zoological is literally pronounced zō-ə-ˈlä-ji-kəl.
@@billballinger5622 now, I’m not insisting you change pronunciation. You can use whichever you please.
Just pointing out that it’s a common mispronunciation of the term.
Google "pronunciation zoology", select American pronunciation, see what you get.
It is perfectly fine for the first o to make the sound "oo" and the second o to make the sound "ah". There are much weirder vowel inconsistencies than that in English, such as how the word "women" has the o making the ih sound. Both pronunciations are good.
@@sciencenerd7639 look, it’s a common mispronunciation. That’s all I was pointing out.
Also, please read what I wrote, I acknowledged the google translate pronunciation as well as how a dictionary uses the actual pronunciation. The zoo pronunciation is simply a mispronunciation that has become commonplace.
I work in the medical field, I know actual physicians, nurses, PAs, NPs, EMTs, you name it who will insist the medical term “tinnitus” has a long i sound in it, making it sound like tin-eye-tis. Most English speakers pronounce it that way, but your audiologist will politely point out (correctly) that it is actually pronounced ti-nə-təs.
Lastly, I’m not trying to tell you how to pronounce it, you can do what you please. But don’t get on here and just make up reasons why the pronunciation is correct/acceptable. It’s only accepted in common usage because most people pronounce it that way.
Go to any dictionary, look for the words zoologist or zoological or zoogeography. You’ll see it uses the long ō pronunciation because that is the correct one. I’ll do you one better, look up the word on RUclips even.
Much like how homogenous is incorrect, but is commonly used everyday by English speakers. The correct word is homogeneous.
Finally thank you
I always thought that the first ‘o’ in zoology is long because this is a compound word. Everyone knows that ‘ology’ means ‘study of,’ like in ‘geology’ or even ‘theology.’ (Note how the ‘e’ in both words is long ‘ee’ sound and not the ‘eh’ sound of a short ‘e.’)
The critical part is ‘zoe’ the Ancient Greek word for life (and a girls’ name). I have never heard ‘Zoe’ pronounced with a short ‘o’ or the ‘oo’ sound like in ‘too.’ So when you add ‘zoe’ to ‘ology,’ shouldn’t it be pronounced ‘zoh ahlogee,’ not ‘zu ahlogee?’
In Spanish, what Americans call ‘zoology’ is called zoológia, with the long ‘o.’ Russian has ‘Зоология,’ again with a long ‘o.’ Since we are not studying zoos, but life, I am of the opinion that we should pronounce it with the long ‘o.’
I realize that language changes over time, and at least Americans tend to mispronounce this word so consistently that the dictionary now shows both ways to pronounce the word. 🤷🏻♀️
I’ve always heard this word pronounced as Zo - Ology. Not Zoo - Ology. If it was the way it’s commonly pronounced in America wouldn’t it have three ooo In the spelling?
Wikipedia (US English) has the IPA pronunciation as Zoology (/zoʊˈɒlədʒi/). After the initial Z sound there is oʊ which the sound as in the middle of ‘Goat’. Then the ɒ as in the o in ‘Lot’ and the l as in the first sound of ‘Lie’.
Wikipedia therefore has the pronunciation as Zo Ology. Which is how I’ve always heard it and thus made me not get why Dave was pronouncing this way.
This aside, great video on what is Zoology.
As the wise Ken said one time repeatedly, they are all from a kind.
You should do some collab with Casual Geographic 😂
Its crazy how they jam all of this stuff into gen bio courses
i have a question. why it's pronounced as zooahlogy?
Thank you. :)
This guy knows everything like what
it's a biological Kingdom of eukaryote bunch exist alongside plants, fungi, and protists.
Thank you chemistry Jesus.
Just the channel I was looking for 😍💘💘💘💘
Why are 13 videos hidden?
They will be released over time.
OMG yes yes yes Zoology...
"Shilly-shally worm"? Nah, you just made that up.
Dave, do you ever stop???
Can't and won't!
What are animals? We just don't know
This video will be right up your street! 👍😘
Well I literally define them in this video, so you should probably watch it.
@@ProfessorDaveExplains haha thanks, I've already watched it. My comment is just a meme-ish reference: ruclips.net/video/Kh0Y2hVe_bw/видео.html
Ah, gotcha.
@@ProfessorDaveExplains mr literal over here
hiya professor
Wow!
Professor, you do not reply to our emails😔
I wouldn't take it personally. Hes clearly a very busy guy! I'm amazed he can hold down a job while doing all these amazing online tutorials! I doubt he's even seen your emails. I know it must be frustrating for you but im sure he hasn't intentionally ignored you.
I'm sure he'll get back to you when he's had chance to catch up on his emails :)
I didn't know tunicates could do that
Sir please move your hands. And please continue this
I'm not even visible in this.
My wife told me that I'm an animal....
You are
Evolution told you too…
nairobi connected
❤️❤️
That tree of life was extremely triggering.
Why?
@@MouldMadeMind Because its very oversimplified and it might get the creationists spitting their mouths
Green nature drink, ocean power, drawings crayon, doctors and molested kids, ;questions for molested when young, also therapists and engineers, only pure scientists
@@MouldMadeMind Because it's highly inaccurate. Like, to a ridiculous degree.
Hello
Having a nucleus is not really a good point for being an animal. Mymaridae do not have a nucleus, but are still animals.
Exception divines the rule, I guess
That is not accurate.
@@ProfessorDaveExplains, there are two lineages that do not have a nucleus in their neurons. It is true ;)
Hey professor Dave I hope you see my message I would love it if you can make a video about the psyche model of magic that says certain parts of magic are backed by science. An instance someone's Beauty care routine could be considered a glamour spell and inner Alchemy the action of manipulating the subconscious to get 1 or various changes of character like being more confident being more forward or being more aggressive this can be achieved with psychodrama and there are a lot of other elements this seems scientific for instance the belief in a god is actually the belief in an archetype the archetype is pretty much like a mask that your subconscious can wear and reveal knowledge to you. I have a ton of other examples of this suppose scientific method of doing magic
No tutorial necessary, that's all bullshit, end of story.
@@ProfessorDaveExplains wait so you don't believe that psychodrama exists and archetypes and herbalism and illusion magic like Criss Angel and David Blaine type Magic and what about dark psychology and understanding body language facial expressions micro-expressions tone of voice usage of language and the Art of influence and manipulation from what I've read all of these things can affect your reality and it's all based on actual science like psychodrama is currently used by psychotherapists... or is it that you disagree with the label Magic
You just named like 18 totally different things as though they are all the same thing.
@@ProfessorDaveExplains no I names 18 completely different things and said that the totality of knowing all these things can be considered magic two people that practice the Psych model of magic understanding how to create Illusions can give you the ability of looking Supernatural understanding plants their usages and how to extract isolate and concentrate their elements can be used to create remedies and cosmetics Understanding Psychology body language facial expressions micro-expressions usage of language tone of voice understanding how to influence how to be persuasive and manipulation can create an illusion that you are an empath there's a lot more within the psychology model of magic but basically what I'm saying is that if you learn all of these talents you can give off the illusion of being magical now revealing the secrets would demystify the whole thing but if you kept the secrets the secret then you would see spiritual enlightened or Supernatural I'm not saying that these judgments are correct I'm just saying that this model of of magic exist
@@ProfessorDaveExplains PS I just want you to know that I love your channel and I think you're awesome I watch all your videos so don't think that I'm trying to argue with you or played the bay Pro I truly do appreciate all the s*** you do
👏🙂
Answer: delicious
Maybe I'll finally get to learn if a sandwich is an animal.
Sand - Latin for it's rough and gets everywhere
Wich - a practitioner of every day magic, like how did you slice that deli meat so thin.
The bread eats the meat and condiments so sandwiches are heterotrophic.
The bread has air holes in it so it's definitely respirating.
So thanks Prof Dave, sandwich is an animal!
So what they're evolutionarily close, sponges don't have a nervous system, cnidaria do, hence the cut-off is at jellyfish, if that irritates you just know that all organisms that aren't fungi, animals, or plants are called protists irrespective of how genetically far from each other they are.
Maybe go ahead and watch the tutorial on phylum Porifera, bud.
Just browsing and searching rage about calling humans as animals
horse??
Jesus is that you ???
Hello.. Incoming freshman heree😭😭😭
doggy go woof!
Please do not animals
I kinda think categorising things as animals even though they lost a lot of characteristics that would make them animals in the first place is erroneous. If an animal evolved somehow into a plant one day then we should just be ready to call it that. It seems so stiff
Cladistics and classification of organisms is not anymore solely based upon phenotypic characterietics, but genetic ancestry. As such, it matters not how much a species has changed, and nothing can alter its lineage.

Thanks Jesus
For supporting slavery.
@@MouldMadeMind they just dont want to talk about that part
