I suspect she is a woman. Be able to live or at least spend long periods of time underwater in a lake "Long periods" is relative and opinion based. Kimberly Jeffries can hold her breath for six minutes even after having drank a load of coffee. Also notice that women are easily capable of outsmarting men, specially men who do not pay attention to ...

Evidence suggests that no creature becomes more intelligent than it needs to be, intelligence is expensive of calories, for example, human brains are about 2% of our overall mass but require 20% of our minimum calorie intake. So intelligence beyond basic survival needs is actually maladaptive for individuals and species. A gecko therefore has a biological ...

She is a normal woman standing in a submerged bin While she awaits the chosen one she sits on the stool. As soon as she hears the coconuts, she stands on the stool and arranges her samite robe to conceal the edges of the bin. She raises the sword aloft and waits for the future king to appear. Clearly there are variations. She could remain sitting with the ...

Their skin contains a set of proteins that will bind to each other and harden when exposed to certain wavelengths, much like dental composite polymers: Composites are placed while still in a soft, dough-like state, but when exposed to light of a certain blue wavelength (typically 470 nm), they polymerize and harden into the solid filling (for more ...

Speed Not Required Give your sword a hydrophobic coating and it will never get any blood on it. The coating repels liquids, causing them to bead up like water on a lotus leaf and just run off. Bonus it stays nice and clean. Edit: A blade made of steel does not mean that It cannot have a coating that makes it repel blood. Furthermore, the surface ...

Slimes can't be harmed with weapons They don't have a solid form. Slash it with a sword, whack it with a hammer, poke it with a spear, and all you get is a wet thud. Slimes can't be harmed by fire They are so wet and gooey. If you throw a torch at them, it would go right out. Even a Grade A magical fireball won't do too much damage. You need a whole team ...

First off let me say yuck!, that is a series of Google searches I can never take back. But as to your question, apparently plants often germinate inside the human body, specifically inside the lungs, as the warm moist environment is good for sprouting a seed. There are multiple reports of this happening with a variety of plants, this was widely covered ...

There is historical record (although old and unreliable) that, in 1031 or 32, Vazul, the grand prince of Hungary, was blinded and deafened using molten lead to make him unsuitable as king. It was not a regular punishment though. Feeling his powers slipping away, [King Stephen] sent messengers in haste to have his uncle's son Vazul brought from prison in ...

Square-Cubic Law tells us that at some size the neck of our giant breaks under its own weight(2), but how large is a giant that has a ring that fits a forearm? Our Giant's finger's diameter is the diameter of the forearm of the human. I am a rather slender person of 2 meters height, my wrist is pretty much skin over bone. To fit my wrist, that'd be $d_{w}=...

An electrode wired directly into the brain's pain centers would provide any level of pain you require at the flip of a switch. We have done this with test animals, mostly mice in order to study pain responses and chronic pain treatment methods. Nothing is preventing us from doing this to people other than ethics. At maximum your subject would eventually ...

Your former projection will be in for a hard time, even if they've faithfully served their summoner for decades. Why? The calcium in bone (and more so teeth, especially the enamel) is relatively permanent -- it doesn't get replaced rapidly or frequently. This is why, for instance, Strontium 90 in nuclear fallout is such a problem -- because it replaces ...

Another classic trait of trolls, is a tremendous regenerative ability. Sometimes to the point where only fire can kill them. So I'd suggest trolls create a chemical in their body that boosts their regenerative abilities, and any damage will increase the levels of this chemical. Sadly (for the troll) this chemical reacts with UV light from the sun, and ...

Not only is speed not required as per Joe Kissling's answer but speed is not able to keep it clean, either. The sword will be pushing through blood as it cuts, it's impossible for blood not to get on the sword. Thus keeping it clean means either a material that blood will not adhere to, or a speed in which the air movement will scour the blade free of ...

Sadly, (for they would be adorable) no. One of the main things that's going to hinder your dear "water boars" (hey if normally sized tardigrades are called water pigletts why not call these ones boars...) are predators. Dehydrating yourself to survive without water/nutriants is absolutely useless if a predator can come around and kill you anyways (...

Probably not I agree that the work is incredible, but ultimately the problem with the design is always going to be the downstroke of the wing. Birds have massively well developed pectoral muscles. In chickens, this is what we mean when we describe the breast meat. It's the largest single muscle group on a chicken and most other birds because of the sheer ...

A real answer is a calculus problem that requires many different iffy variables that will be difficult to determine. So I am just going to ballpark it instead. In a lot of places, I have rounded or just taken sweeping approximations. It should hopefully be within an order of magnitude of the right answer. However, I think getting a realistic answer to this ...

Slimes are very big. The little puddle on the floor is to the body of the slime as a mushroom is to the mycelium below. The mushroom is the size of your finger. The mycelium is the size of a car. Most of a slime's vast biomass (and even vaster water mass) is kept safe from dessication in the interstices and cracks of the substrate. Only a tiny bit ...

Such a creature would most likely dine on a diet of the finest pixie dust Unfortunately, the creature you describe is so far from reality and the laws of physics that we are pretty much 100% in the realm of magic. First off, let's talk eyesight. The metaphor of a baseball at 0.1 m isn't quite good enough. Let's take a look at the most likely food ...

I'll take a stab at this... First things first, I'm finding it hard to find exact figures about the weight of a macaw's feathers but a general consensus seems to be the bird itself weighs around 1kg (depending on species, but I assume you want a scarlet or blue and yellow as they are the most famous and both weigh 1kg). According to this answer on Quora a ...

Art Imitates Life Lucky for you, the implantation (or rather reimplantation) of endocrine glands is already a thing. During parathyroidectomy, it is common practice to perform autotransplantation of a portion of the hyperactive tissue. This is usually done in the muscle tissue of the neck or forearm. This is a whopping big parathyroid, much larger than the ...

In addition to Ash's answer: You assume that every lifeform spends its entire life learning indefinitely. This is just plain incorrect. Not only could you look at the elderly of most species and see that at some point the intelligence does not seem to improve anymore or in some cases by tendency degrade in old age. (e.g. Humans) But some animals learn very ...

Do not make a problem where you do not have one Demi-gods have been born by fully human mothers in hundreds of myths all around the world for thousands of years without anyone ever making an issue out of it, so you do not need to make an issue of it now. In fact if you do make an issue of, you are more likely to hurt your work than help it. This is because ...

Every drop of slime is a slime. If you splash goo everywhere while hitting, they'll each act as separate conscious slimes. The drops on your armor will search the gaps. The drops on your weapon will climb the blade. The drops on your boots will climb your legs. The drops on your face or hands or flesh in general will eat you and grow and eat and grow and ...

Did you know some turtles can breathe through their butt? Here we have a similar thing: a humanoid lady clad in long folds of her own skin, which just so happens to look like samite. Which, after some googling is apparently some kind of embroidered silk. This species has a peculiar mating ritual: the males migrate over land towards ancestral spawning ponds ...

Manatee are believed to have given origin to the myth of the sirens: their swollen breasts while breast feeding their younglings, their humanoid appearance, the human sounding sounds they can emit, together with the months long forced heterosexual abstinence experienced by old time sailors, could easily explain the "chanting naked ladies luring sailors to ...

Even if they survived Zeiss Ikon's way, there's not a hope of surviving this: The neurons in the brain don't get replaced over this sort of time period. It is widely understood now that new neurons can grow, but when a nerve cell dies, it is gone for good. The nerve cells in your brain today have the same molecules of DNA that they were initially created ...

If it's pure steel? Hell nah. But there are other options. The scaly-foot gastropod, also known by the considerably more badass-sounding names of iron snail and Chrysomallon squamiferum, hails from the deep-sea thermal vents known as black smokers, deep-sea vents from which water gushes constantly. That water, by the way, originates from below the mantle. ...

Pretty easily, even if it will be really messy and obviously painful. Drive a red-hot spike through the ear canal, about one inch deeper than the eardrum membrane. This will destroy the tympanus and the small bones of the ear, and cauterize the vestibular ganglia and the cochlear nerve. Obviously, you're also looking at a pretty grim fatality rate. ...

Same as for normal living beings. Natural selection: only demigods who manage to not kill their mother in their fetal stage get the chance to be born and pass their genes to their descendants. All others are simply subject to Darwinian selection. If you want to sprinkle some divine intervention in the picture, than the deity who impregnated the woman ...
