The Biology and Evolution of Cassowaries
Cassowary are large, flightless birds known for being extremely dangerous. They are not as aggressive as their reputation might have you believe, and are in fact extremely important seed dispersers for the rainforests where they live. Have a look as I explain their phylogeny, habitat, behaviours, and conservation.

The Biology of Four-Horned Antelopes
มุมมอง 82819 ชั่วโมงที่ผ่านมา
Four-horned antelopes are unique bovines that are the only wild animal alive today with four horns. As shy animals, they are poorly known, but are increasingly brought into conflict with humans and domesticated animals due to habitat fragmentation. Have a look as I explains their phylogeny, habitat, behaviours, and conservation. All pictures attributed to Animal Analytics were taken by me perso...
The Biology and Evolution of Nautiluses

Nautiluses are the most ancient group of Cephalopods. They originate from 500 million years ago, but are amazingly still around today. While they are from the same class as squids and octopuses, they are highly unique and have many features not seen in the other living Cephalopods. Have a look as I dive into the nautiluses.

Vampire Bats: the Only Mammals to Feed on Blood
Thank you for your amazing quality work. I really didn't understand how your channel still has so few subscribers. Hang in there and keep them coming when you can.
numbers are very low ...Car accidents , destruction of habitat and inbreeding . Sadly this relic of the megafauna era in Australia is struggling . I doubt it will survive in the wild and only specimens will be a captive breeding program . Stunning bird from a very ancient time .
are the introduced cane toads a threat to them since cassowaries can get poisoned from predating on them like many other opportunists
penguins are also flightless birds, so what makes then different from these other flightless birds? some of them are pretty large, too!
There is an awesome kiwi band called The Beths, their song Expert in a Dying Field is so good, you should check it out if you have never heard of them!
nice video, impressed you included some original photography !
I like to include some of my own photography when I get the chance. It means actually doing something with my photos instead of letting them gather dust in my hard drive!
Always eager to hear a Kiwi take on the failures and shortcomings of their cross-Tasman neighbours! 😉 Love to hear your version of the Great Emu War! (Greetings from Canada)
They may not be alive today but did those early birds get the Worm?
I would have loved to see Giant Moa's and the Hawst eagles 🦅 before they went extinct. Same as the elephant birds and dodo birds. Also getting to See Terror Birds would have been INSANE
One of the most fascinating animals today...
cool
I think people forget just how much megafauna was wiped out by the Polynesians in their island hopping. So much unique fauna that evolved on Islands was decimated by the Polynesian peoples - particularly New Zealand's amazing megafauna, and Hawaii's larger species. And somethin else, that nearly always goes unspoken, is the fact that virtually all Australian megafuana-extinctions (during the Holocene) occured only after the Aboriginals' arrival.
Well that’s only part of it
Yes! Thank you for saying this! The natives had no concept of preservation of species and/or what it meant to over hunt and the consequences of their own actions. It's wonderful that we civilized people know better today and have set up safeguards to prevent over hunting/fishing/farming from occurring and ravaging the Flora, Fauna, and the land itself any further. We may not be able to bring back the countless unique creatures that the Aborigines and Polynesians drove into extinction, but we can (and must) protect the ones we have left today and heal the land as best we can for future generations to appreciate 🙂
@@HunterChristian-o7o Really?! 😂
Observe a footprint of an Emu or Cassowary and you are looking at a Dinosaur footprint. Fossilized you would not know he difference. "Chickens are Dinosaurs" Save the Kakapo
Just saying but I would love to see a video on the genus bison and the genus is made up of only two living species the American bison or as it is also known as the Thunderbeast and the European bison aka Wisent but the rest of the species in the genus are extinct and these include Bison schoetensacki aka the Pleistocene wood bison, Bison antiquus, Bison latifrons aka the long horned bison, Bison occidentalis and Bison priscus aka the steppe bison and the ancestors of American and European bisons first appeared in south and Eastern Asia between 2-3 million years ago and the ancestors of the American bison went to North America where they evolved into the American bison while the ancestors of the wisent migrated from south and east Asia to Eastern Europe and the Caucasus and both species of living bison are even broken down into subspecies with the subspecies of the American bison being Bison bison athabascae aka the wood bison which live in forests and they are the largest land mammal in North America weighing more than a moose with a large male wood bison reaching up to 2,000 pounds while an adult female bison weighs 1,200 pounds and an adult moose weighs around 1,500 pounds which means a male wood bison can be around 500 pounds heavier than a moose. The other subspecies of the American bison is the more commonly seen, more recognizable and more popular Bison bison bison aka the plains bison and these are the bison that inhabit and roam the Great Plains and prairies of the midwestern and western United States and they along with the wood bison used to inhabit the eastern United States with their range in the eastern us spanning from New York in the north to Florida in the south and from the Mississippi River in the western part of the eastern states to the Atlantic coast however by the 19th century they were hunted out of the eastern states and now the only places in the us where wild plains bison are found is the western and midwestern United States. But while the American bison has two subspecies the European bison aka wisent had 3 subspecies and these subspecies are Bison bonasus bonasus which is the only living subspecies of the wisent and it inhabits the Forests, Woodlands, grasslands and plains and its currently restricted to central and Eastern Europe including the nation’s of Belarus, Lithuania, Poland, Russia, Slovakia and Ukraine however the other two subspecies of the wisest are extinct and the other two subspecies are Bison bonasus caucasicus aka the Caucasian wisent which inhabited the the Caucasus Mountains and it was hunted by carnivores like the asiatic lion, Caspian tiger, steppe wolves and the Syrian brown bear however in 1927 the last Caucasian Wisent became extinct. The other subspecies of the Wisent to go extinct was Bison bonasus hungarorum aka the carpathian wisent and the carpathian wisent inhabited the Carpathian Mountains in Moldavia and Transylvania and it went extinct in 1852.
Someone just made a video, literally this week, comparing both Bison species on TH-cam. I think it was made 2 days ago if you search for it.
@ oh okay thanks for letting me know about the video.
This was my favorite video! We appreciate all your facts and knowledge. Thank you kindley sir 🫡
Minor correction: giraffid horns are called "ossicones" not "osteoderms"
Pronghorn are thought to be missing their predator, American cheetahs.
I really enjoyed this. Glad to have stumbled upon your channel!
Winner of the redundancy award goes to... The Four-horn Four-horn Four Horned Antelope!
Can U please do water bears tatagrades🌊🐻
Haven’t commented in a while but. Your video are some of the best ever on TH-cam. NEVER stop these wealths of information. What do you study btw?
I have a masters in pest management. I have degrees in biology, classics, and history. It's an interesting mix, but follows my interests 😄
@ pest management? Would have never guessed. What type of pest? Insects? Are you an entomologist… because I’m an entomologist would be a crazy coincidence
They remind me of the little muntjac deer we have in the uk though they look a bit less sheepish and more deer-like. I love learning more about animals like this, it’s amazing how many mammals are not really talked about even or maybe because they’re common in their home ranges but haven’t been made a tourist draw to westerners. This first time I discovered the existence of the black wildebeest I was kinda outraged! How could so many documentaries focused on African wildlife miss a goofy, prancey bovid with a double Mohawk, one on its face!
My favourite silly little blighters, fun video!
Loved this video! :D
I love Nautiloids but my favourite Cephalopods are the Ammonoidea even though they are extinct. This is the first of your videos I've watched but definately not the last. ❤
You forgot to mention C’thulhu…
I am currently using speech to text so enjoy whatever the computer figures out I'm saying Thank you very much for that I cut opals and a part of opals that you're getting Coober PDR specially I called bellam knights which are nautiloids. I recovered a clear specimen which had something that look like a straight tube in the centre now I know what that is thanks to your video
Is the accent new Zealand?
I prefer octopidi
Fascinating, thank you! Have you ever done a video on Ammonites? Where I work, there is a fossilized ammonite shell that is almost a meter across! It's been on display for years and I always enjoy seeing it.

Love you video can't wait to see more haha
Very enjoyable. Unique style. Strongly disagree with your plural choices. Looking forward to more content from you! 😊
Evolution is entirely imagined.
That’s quite the assertion, 🧌
@ Yes evolution is an assertion.
@ sure, only if you ignore the mountains of evidence that proves otherwise 😂
@@nektu5435 Genetic entropy disproves evolution. You probably don’t even know that Neanderthals had a larger genome than we have today.
@@nektu5435 Except you can’t show any evidence for evolution. We are only degrading over time.
Maybe a video on Shrimp. From tiny grass shrimp to giant ones.

Hay man can you please 🙏 do a episode on water bears🌊🐻
cool! i wanna see one
wish we knew more about these creatures with such an ancient lineage. gonna need EV Nautilus to step it up!
I watched all this vid - which was very good - waiting in vain for an image of any kind of the animal ratger than its shell.
Love your videos!
Just in case you didn’t notice, the tusk shell you showed actually has a hermit crab inside it, not the original organism
@3:13 Good catch! "That's not a cephalopod in that shell!"
I'm pretty sure "octopuses" or simply using "octopus" for both singular and plural have been considered more correct than "octopi" for a while now.
Probably, but it wouldn't stop someone going "well, actually..."
@@animalanalyticsas someone who had both Latin and Ancient Greek in school, i appreciate you taking the time to point out those variants, and also appreciate you opting for "octopusses" if i want to be mean, i typically go for "octopodes" but pronounce it _ok-TOP-od-eeze_
I'm speakin 21st century, so theyre lucky it's not "funguses" and "nemesises" all over the place! @fariesz6786
Yes, ‘octopodes’ is more linguistically correct, but many people would look at you strangely if you used that term. ‘Octopuses’ is a good anglicised plural for use today.

Thank you very much. I have learned a lot from this video.
Nautiloids were the end product of Ammonites.
