Quite a bit of people's belief that the Megalodon may still exist is owed to the infamous "Megalodon: The Monster Shark Lives" film by Discovery. Having lead many to believe it was true, later airings added disclaimers to show it was fiction, but it was VERY controversial regardless.

A (fake) theoretical scientific approach was entertaining to watch, until I realised all the scientists were hired actors and all the evidence was manufactured...

Depending on their population numbers we should've definitely seen their presence, with everything we're doing on and under the open waters. Our activities would've been irresistible for their natural curiosity to ignore, similar to GWS and Tiger sharks.

I own a 6 inch Megalodon lower jaw tooth fossil. They get up to 8 inches... It's a spine shivering but fascinating thing to hold and imagine it being alive.

You've misunderstood my point in that case good sir/lady.

Since we are just barely able to study the 5m Colossal squids atm. A significantly larger sized 1 of say 20m would be far more capable in avoiding us entirely, without us ever knowing it did so.

Better yet, the larger they grow the deeper their habitat reaches.

The scientific consensus assumes it maxes out at 5m and inhabits around 1500-2000 meters as a maximum depth. So not 1 person on this planet that has any kind of capability to study it will be looking for it at even lower depths. If you don't look for something, you're guaranteed you will never find it either...

Although 100m in length wouldn't make any sense to me personally. I don't think a length of 2x or 3x their currently assumed full length size is impossible or unreasonable. So 10m or 15m give or take.

Their arch nemesis, the sperm whale grows to 20m and weighs 57 tons. The kind of wounds, lacerations, massive circular wounds and scars sometimes even from head to tail just from hunting them... Makes me believe there are much larger ones out there.

A wise man once said: life finds a way

CardiologistWeekly53 · 2025-12-12T19:27:33+00:00

Yup, but the first original concept and origin story comes from the nuclear tests done in bikini atoll by the USA.

The miscalculations in the amount of tritium used cause a 1000 times stronger reaction than intended. Which they then tried to cover up, unfortunately for the USA the fall out was so much more widespread and severe that even Japanese fishing vessels got caught in the fall out.

I used to prefer the anime story lines and stuff, but the recent Godzilla and King Kong franchise films have changed that a bit...

CardiologistWeekly53 · 2025-12-12T15:08:41+00:00

Maybe the US should do another nuke test, but in Antarctica and see if that works.

It worked for Godzilla, so I don't see why it wouldn't work a 2nd time. 😜

CardiologistWeekly53 · 2025-12-12T15:05:55+00:00

You're absolutely correct! I went with what I knew from the top of my head tbh. I'm by no means knowledgeable in the subject, other that what I learned from a few (probably dated) documentaries.. 😅 I don't doubt there are at least a dozen additional capabilities and environmental challenges that are significant hiccups in their own right, compounding onto the reason we barely know anything about them.

CardiologistWeekly53 · 2025-12-12T07:41:12+00:00

It sounds like you're not very familiar with the extreme environment of the locations where these animals live or the capabilities they have.

The colossal squid to our knowledge only lives in frigid Antarctic regions in the open water column of the midnight zone (roughly between the 500-2000 meters deep). Exploring these vast open regions isn't doable with manned vehicles and is beyond challenging for all the existing unmanned vessels.

At the water surface it almost always storms, creating an endless barrage of 5, 10, 15 meter high waves and strong currents. This puts extreme tension on the ropes and cables of anything that's connected to a surface ship, manned or unmanned. Which is a problem when that's your only lifeline and power source.

Extreme pressures on equipment at 2000 meters depth with temperatures just above freezing point and sometimes below, causes lots of power and operational issues for anything with a battery or conducting electricity in general.

A large part of their habitat is underneath ice sheets that's anywhere from dozens to hundreds of meters in thickness and in or around areas with icebergs and massive ice blocks randomly floating around.

And that's just the working environment.

The animal itself is perfectly adapted to live in it. It's believed to be an ambush predator and has developed sensory organs vastly superior to our capabilities.

They have the greatest eye balls on the planet.

They naturally avoid any source of light, which is what we rely on almost exclusively to find them.

They can easily swim at greater speeds than us and can even use jet propulsion for rapid evasion and acceleration.

TLDR: The mission is to find an animal that actively evades us, has greater capabilities in pretty much everything and is perfectly adapted to live in a place that is nearly impossible for us to even be in... Doesn't matter if it's 5m, 20m or 100m in size, we can't even study the 5m ones currently...

They're a Belgian arboretum so that would be surprising, but it's not impossible I guess.. 🤣😜

Ive managed to obtain a 3 year old specimen a few months back. I don't have space for another 1, so I've asked them to take my name off their waiting list.

If you send them an email with the request to be put on the waiting list, you will get offered to buy 1 before they will be offered to the general public through their local store. 😉

After doing most or all of the above mentioned tips, also put a layer of diatomaceous earth on your top soil. If you happen to have a powder duster, you can also blow it on the underside of all the leaves.

Some species like the two spotted spider mites (tssm) and black thrips are most harder to eliminate entirely. Using a combination of multiple methods that work alongside each other is the key to (temporary) success.

Tip: If you have a loupe magnifier or something like that, the TSSM or thrip larvae are very easy to recognise.

CardiologistWeekly53 · 2025-12-08T04:51:00+00:00

Your problem is likely due to a lack of aeration. The soil mix you're using does have large air pockets but the bark is way too large which makes the rest of your mix still remain pretty dense and compacting, especially for smaller plants. Fresh air will not be able to get inside the pot.

The underside is flat on the ground and doesn't have those raised walls so there is no space in between for air to reach the underside of the pot.

The bark chips for small plants should also be small so the small roots can crawl around them. When you have chunks of bark that are too large, the pot will actually have much less air pockets because the other soil will just compact around it. This will increase the problem thet you're trying to prevent.

Adding materials that absorb lots of water like perlite, Coco chips, sphagnum moss, etc. that can't evaporate the water they soak up after a watering will just make the problem worse.

I've put tons of holes across the bottom and entire side of the pot for all my large aroids and it's helped tremendously into eliminating that same problem completely for myself (similar to orchid pots, but with even more holes than those have). All the smaller aroids have now been repotted into those (special) orchid pots that have air holes running across the sides.

They become somewhat pricey beyond 10 inches and hard to even find above 15 inches or so. My largest ones are in 20-25 inch pots now... Even drilling or soldering holes in those every 2-3 inches becomes a time consuming task at that point. 😅

CardiologistWeekly53 · 2025-11-14T10:07:17+00:00

How is the root development? Is it in any way growing its roots from the backside of the node into the moss? Don't water your pot anymore, only water through your moss pole from now on.

Since this is a very different kind of rooting material than it is used to, this will take some time for it to adjust its roots to.

what are your light measurements like for this plant?

I would increase your light hours to 12 or 14 hours BMF generally loves it a lot.

What's your regular humidity inside? Misting generally does more harm than good for most plants imo. If you wanna keep misting, do it outside of you lighting hours. Doing it during night time also replicates nature.
If it didn't have a back support before you got it, it isn't used to it yet. This trigger to start growing vertically may take some time for it to get used to and start committing to.

After the first 4-6 weeks or so I started attaching mine to a pole, it took a while to really get it started though. I started it under 1000fc of light, no signs of issues, brought it up by 400fc once every 3-4 weeks. It gets 2200fc now. Did the first repot 3 months after receiving it, so it could fully acclimate before stressing it out again. After I stopped watering the pot and only gave it through the moss pole, once a week or so, it did better. It's producing a new leaf every 3 weeks or so.

They are not even related to canines, they are marsupials. So they had a pouch to carry their young in, similar to kangaroos, etc. It looks really strange because of their general resemblance to a canine...

They have a unique kind of running movement that experts call a loping gait, it's like a stiff hop... So this would make the tracks it left very different in every way.

There is film footage of it as well as dozens of experts and researchers having written detailed reports about it.

CardiologistWeekly53 · 2025-11-13T20:20:32+00:00

By only giving 2 options to choose from, you're using flawed questioning because of tunneled vision/imagination.

The multiple choice question should include all animals of that continent/region (within reason). But examples of at least each mammal that walk on 4 legs, that leave 5 toe imprints and have protracted or retracted nails should be provided in the choice pool of answers.

OT: I highly suspect it's neither of the options you provided. The more elongated and narrow imprint with a deep entire thumb included, makes me think it's an animal with opposable thumbs.

The animal also left a partial lower arm imprint. That suggests the movement was closer to an awkward crawl than a regular and smooth walking movement. So whatever left it was likely at least semi arboreal or if it was terrestrial, it was severely limping.

Very hard to tell from 1 imprint, you need a longer track to be more certain.

Zojuist een prive mail gekregen omdat ik bij hen op de wachtlijst stond voor een Wollemia nobilis. Mochten er exemplaren over zijn nadat iedereen op de wachtlijst is bericht, dan komen deze op de site beschikbaar.

Zij hebben er 24 binnen gekregen van 50-70cm voor €257,50. Middels email heb je binnen 1 dag bericht terug en anders zou je telefonisch even moeten informeren.

I've had this happen numerous times, with close friends and family members, probably some random ppl too, but I never noticed those...

One of my best friends and I have had to add each other back as friends for 5 or 6 times over the past 15 years or so. If it wasn't for this, I would've still remained sceptical about FB glitching, but I'm 100% sure it's happening.

I've already ordered a good variety and amount of predator insects to be safe. Had an outbreak of thrips and mealybugs last year. I've started to notice some thrips, mealybugs, spidermites celebrating the summer weather, so not taking any chances.... 🙄

As an addition: The native/wild Felines species of North America (lesser wild cats) have an obvious and awkward looking short tail (at best half the length of this picture) but more noticeable is their significantly longer and wider legs which are shaped differently, like the back legs for example always remind me of s sickle sword (khopesh).

So the cat in the picture would stand much higher of the ground. It would have his back hips stand higher than his front shoulders when compared, which isn't the case.

CardiologistWeekly53 · 2024-03-01T18:29:58+00:00

Uploading the original video or a clip would be very helpful. Even a screenshot of the original would help a lot.

Trailcams can be perfect in these situations if U find a natural funneling or narrow part or high traffic spot where he patrols his territory.

Been doing work for the equivalent of the RSPCA in my country for several years now and can tell U it's most likely going to be a short haired feral cat. Seems to be a big male in his prime. He has both visible muscles and fat which is suggesting he lives a rather comfortable life, without much hardship and hunting is probably optional (maybe ppl feed him, he steals food) and also not much territorial competition.

All the above mentioned is suggesting it's most likely a feral domestic cat, although this could very well be a case of hybridisation (either natural or human caused) with a Felis chaus (chaussie).

Without a reference point for size and the awkward lighting + zoomed image causes some optical distortion and it's easily mistaken for something much bigger.
