Kinda disappointed. A lot of interesting details about octopus in general were left out, and the whole reason for clicking on video was never actually brought up. What would happen if an octopus lives past 5? How big could they get? Why can't captive octopuses live longer?
Pretty obvious why any captive animal doesn't live it's full potential life span - humans presumptuous research therefore over-feed them or feed them incorrectly
@@NZCLUB_reals indoor housecats on avg live longer than ones allowed outside; captivity really isn't that bad considering they aren't at risk from predators; feeding isn't the problem either; i'd say the main issue is stress from containment, and excessive human interaction; there are some real jackasses that bully zoo animals and then are all surprised when the animal lets em have it
Octopus are smart. I found a Octopus in a gallon glass jug with the lid taped on and left in the sun on the beach. I let it out and I was surprised at how big it was and that it fit in the jug. For some unknown reason someone had locked it in the jug, but I let it out on the shore in a tide pool. I expected it to s urry off in to the ocean but it hung around and it thanked me. We sat on the beach and watched the sunset. That Octopus was grateful, it wrapped its tentacles on my hand and arm with out suction, it just sort od caressed my hand, I think it was saying thanks. For a year when I visited that beach and tide pool I most always saw it, it would come out of the ocean to hang out with me and my buddies, that Octopus was smart, it was an interesting experience and encounter. I think they are sweet critters. I would put a bait fish down by it and it would eat it. An excellent lil creature, and very smart. We put a fish in a mason jar once and screwed the lid on, the Octopus opened that jar to get the fish, that octopus was a good lil friend. That was over 50 years ago, I hope it is doing well. And I don't think they actually know how long an Octopus lives, just like sharks, an oceanographer told me they really don't know much about octopus, they are an inigma in a way,,,🐙🐙🐙🐙🐙❤❤❤❤❤😮😊
I doubt it was trapped in the jug, they are really strong, and probably could have screwed the lid off or wiggled it loose, despite the tape. That’s how the can open the strongest clams.
They're more curious than a cat.🤣 I kind of become obsessed with them when I started diving 25 years ago. I've dived with hundreds of them over the years. A guy in Thailand got stabbed by one. Not deliberately. It wasn't a gang octopus 🤣. The diver was playing with the octopus and had a knife attached to his BCD in a sheath. The octopus pulled the knife out of the sheath and swung it around like a child would. Then stabbed the diver. Not fatally. Just a cut, but it showed it's curiosity and fascination with new objects. And a great story for the grandkids🤣.
I knew that Octupus. He was living in that jar bc he lost his lagoon in the divorce. He mentioned some nice person use to visit and spend time with him while I was gone. I suppose that was you. He really appreciated your visits.
Deep sea creatures are larger because of the cold. It's the square-cube law. Heat exchange (i.e. loss) is proportional to size squared, but heat production and capacity are proportional to size cubed. The bigger you are, the better you are at producing and retaining your body heat.
@@COEYRNits easier for me to understand from a maths perspective: Imagine two cubes and one is 3times bigger yhan than the other Basically the bigger cube has all its lengths three times its size however its area is increased by nine times this also means that its volume increases 27 times This means bigger animals have a more stuff inside of them compared to stuff like skin (surface area)which makes it way easier to retain heat as there is less area for heat inside the animal to be lost because the area outside the animal is way smaller in comparison to the volume inside
@@areminderofwhatweare I know and that's why I said life isn't fair. My teachers were adamant that a Latin Word must have a Latin ending to be correct. I was taught Octopi. I was taught octopuses is wrong. But apparently my teachers had not caught up from their education and how language evolves and eventually in the 19th century around The 50s It became octopuses Due to the English convention of adding S or ES for plural. Fish is a really fun one. Fishes is actually correct when you're talking about multiple kinds of fish even though fish is plural by itself.
Some whales had skin marks of sucker diameter that was re-calculated to arm lenght and width of serously giant octopus. Also depth of claw scars from some squids on big sperm whales were re-measured in huge proportions of the prey as well. Recently and again there was found half of a whale bitten in half by one single bite through... Megalodon might be secretly still rulling the oceans...
A thirty foot long, 600 pound octopus is a man-eater without a doubt! We just haven't seen it or recorded it. The smallest octopus at around 5 inches and less than a pound is the blue ringed octopus and it's far deadlier than the biggest octopus! 🦑
@@czarcoma Well they can (beak is good enough) at the very least. It will happen in captivity most likely tho, on the depths these guys live there is close to 0 humans, and a bunch of rubber, steel and plastic with some meat inside is definitely not appetizing. Human corpses however...they most likely already tasted in the past.
@@alexturnbackthearmy1907just because they CAN, doesn't mean they WOULD. like I said. NO EVIDENCE an octopus that large will hunt and eat humans. Just like orcas have the capability but don't eat humans.
It could be because of their life span, but octopi(octopuses?) Lack culture, that is the passing of generational knowledge. If youll hear my long rant, there are 3 factors we have largely determined that are necessary to reach high(human-like) intelligence. Capacity for intelligence, this is a sufficiently complex brain and nervous system. Ability to maniuplate fine tools, fingers or octopus arms would meet this. Lastly culture, the passing of knlowedge between generations. Youll find that the smartest creatures outside of humans tend to have 2 of 3 of these. The capacity for intelligence then either cutlture or the ability to manipulate fine tools. Octopus lack culture and things like orcas lack the ability to manipulate fine tools. Its also up for debate whether a water based creature would be able to reach this level because of the inability to really utilize fire. Fire being a keystone of humans progress from cooking to utilizing it in making technology. There are underwater vents that could be used similarly, but these would be highly geographically restrictive to where society could form.
@@imALazyPanda nay, do we use more electricity now?..with burning of hydrocarbons mainly for transportation. As far as transferring culture goes, with longer lifespans, maybe there would be some adaptation with brooding, or pod formation than the currently random dispersal of babies.
That caused problems in WWII when French forces placed themselves under British command when France fell to Germany. They had French handling motor pools and told to provide enough fuel for each vehicle for 500 miles and the French solders instead provided enough for 500 kilometers.
Yeah, I live outside the US, ie: most of the civilized world and find all the references to pounds , feet and degrees fahrenheit as unhelpful. If you intend to give a quasi scientific information video then giving metric quantities first should be a given, with maybe an imperial /US measurement added on.
Deep sea Octopusses are only seeming smaller. The water pressure at one mile is oppressive and Octo’s realise their actual size after equalised and decompressed at shallower depths. Love Octos.🐙
I’d beat up that like button before even watching your videos because I know your videos in your content are very educational and very good on many levels. I'm just saying!.
There's that slurp! Hi Steve! Great information, I didn't know about their age, growth and temperature differences! Thank you for sharing all the information! There's always an exception!
Some of us like videos for good content, and dislike for bad. Watop is one of the most subtle requestor of likes and just because he said it twice doesn’t make a solid content bad.
I think of "hit the like button'' like the game kids play with daisies. The first time I hit the like button. The second time I hear "hit the like" I hit the dislike or thumbs down button. Game on
on one of your projects or ventures, I'd be interested to have you guys interview each other.. -some day. I really enjoy your voice, personality, writing and presentations on a few channels I've discovered you on.. just "thank you" for keeping the standard, and the presence online..
I wish they would live as long as humans. I think if they did they’d probably develop complex culture and we might have another intelligent species to converse with. Might need to stop eating calamari though that’s a downside..
Still waiting on an answer to the question posed in the title. Those cold water outliers aside, what happens if octopuses survive beyond their standard mating cycle/life span without mating?
I would ask the octopus what they prefer, however I wouldn’t worry about it, octopus are very intelligent and almost certainly can make the Fahrenheit to Metric conversions in their head pretty quick 👍
Even though it's mentioned but not pointed out, another factor for the deep-sea gigantism is the "oxygen-rich waters". Almost EVERYTHING grows bigger in situations like that. That's why we had two-foot dragonflies in ancient times. More available oxygen. 😳
Imagine if there was an octopus that survived and lived in the ocean of either the North or South Pole. It could be as huge as the octopus from the movie "It Came From Beneath The Sea."
The fact that every video I see has someone commenting about how they don't like the "hit the like button" thing is insane 😭 Like I empathize but if you're really that bothered just ignore it and don't do anything lol, or find a different channel and watch that for a little while before coming back or something Anyways!! Love this video, octopuses are my favorite animal :3
3:09 "Preferred temperature for common Octopuses ranges between 59 & 60 degrees Fahrenheit"..... If it is that fussy it's in a world of hurt once "global warming" truly kicks in!
As far as the bumps on the smaller octopi, I would guess that they are the same(ish) mass, but rather the pressure requires them to adjust their skin to keep the pressure manageable... octopi have a muscle that provides them the ability to manipulate their skin in all kinds of wild and bizarre ways, but an octopus under less pressure wouldn't need to use this all the time. (for example, the blob fish explodes once it leaves the depths of the ocean). what would be interesting to see, is whether these octopi can safely travel the mile difference in depths without the pressure change killing them (even if slowly). that would confirm the hypothesis 😁
Experiment needed. Catch a normally small octopus, put it in a cooler tank and feed it more than it's normal routine diet. I wonder if the octopus will grow larger and live longer than it's normal life span and if mated, will it's offspring be larger?🤔
CAN YOU PLEASE USE METRIC SYSTEM SO NON AMERICANS UNDERSTAND TOO? I mean, if you do it on purpose to not use it, I get it, it s stupid but I get it, but if you didn t think about it..just please do it.
Besides generating more body heat. Is there more oxygen compressed into the water at that depth also?? I honestly wouldn't know. but I do know that higher oxygen % is 1 reason land animals used to be so big.
❤❤❤❤u got this revelation !! Wow Amazingly some new words are being fused in ways that inspires my emotions =‘ignites!! The word u translate is 💯 %❤❤❤ Words are 🔑 ❤❤❤ Amen o 1:39
Once on Discovery channel they said that octopus can double its size every 3 months if has enough food. Therefore if it lives for long enough... who knows from where fairy tales about Kraken come.... I ponder if there's relation in effectiveness of digestion of proteins and volume of oxygene contained in sea water. Colder deeper water contains more oxygen that supports metabolism and growth meanwhile warmer water closer to surface contains less oxygen in tropic seas. Also the water pressure in deep ocean is factor supporting need of big body that can handle everything related, physics as well as chemistry, to travel from depth to surface and back. Some cephalopods have ammonia in their body by nature. If they get in warmer water it kills them. They must remain in cold water to avoid lethal chemical reaction of ammonia with warm solt water. Experts of astro-biology claim that cephalopods are so exceptional and extraordinary form of life to all other species that probability of their extraterrestrial origin is very high. It's not their fully developed embryo what they suppose to come passengering an asteroid but amino acids which might fall into ocean billions years ago and evolve into species with abilities like no other.
Wondering if the bumpy skin (~8.50 into feed) is an echolocation defense against hunters such as whales or dolphins. Suggestions and comments welcomed.
Global warming CO2, methane etc U definitly know If you think that is a lie, what do you do on this Channel? Its all about research and science and if you dont belief the global warming (because of co2 etc) is real you dont belong here
What were your sources? For differences in size, you provided most of the clues, but the conclusions were off. Size is a function of a) surface area (squared) to volume (cubed) ratio, so bigger means able to keep heat created by metabolism; oxygen variability (more = larger); and food is necessary for size, but the ocean floor is rich with this (not the opposite as stated, which is true only if you’re a pant needing sunlight) as it literally falls down in abundance as organisms die above.
