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 ...

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 ...

Instead of fat, elves store energy as ethanol. Fats are the most dense form of food calories. Ethanol is a close second. From https://biology.stackexchange.com/questions/28511/what-is-the-most-condensed-form-of-stored-energy-used-in-biology Rather than pack on bulky fat, elves convert calories to ethanol and store it in their blood spaces and ...

Everyone else is speculating when there are proper reality check examples. Flight suits that allow for free movement of wings, legs and tail are a thing. Some also contain diapers, so that your bird won't poop on people's heads. These things are even fashionable. Someone even managed to bedazzle their pigeon. Your flying people could wear such harnesses.

Fat or adipose tissue carries out some very important functions, so if the elves are anything like humans—or like any sort of mammals—they need fat to survive. Long term energy storage is just one thing, but fat also produces hormones, contributes to thermoregulation and other good stuff. You know that friend of yours, the one that can eat ...

Use their attraction towards magic to drown them into poop It's too exhausting to renew all these expensive defense mechanisms. There is one resource the kingdom will never run out of: poop. Let your drowning tank refills itself, as monsters are irresistibly lured toward the huge pile of magical artifacts you placed at the bottom of it. It is actually a ...

Why would ants unearth pieces of gold? What evolutionary purpose would this behavior serve? It makes their chimneys work better. The workers gather the gold and bring it to the colony. The soldiers use their large powerfull mandibles to shape the soft gold into roughly flat flakes which they distribute around the nest site. The gold's reflection of the ...

Maybe they could have mating rituals like bowerbirds, in which the males, as part of their courtship display, strive to create visually interesting displays outside their bower (the hut-like structure they build for females to come in and mate with them). As the wikipedia article says: In and around the bower, the male places a variety of brightly colored ...

Make it really, really smart Literally seeing the future is, from a perspective of modern science, impossible. Even theories that may allow some degree of time travel through relativity run up against problems when trying to resolve predestination paradoxes and the like. Most modern science fiction stories tend to prefer branching timelines to linear ones ...

The monster doesn't have armor - it has blubber. Bullets don't bounce of the monster - instead they penetrate, but not deep enough to pass through the protective layer of blubber. The blubber isolates the bullets and then spits them out over time. But the monster is allergic to this special wood. Instead of expelling the wood shards, the wounds close ...

This is the four-eyed fish: It has only two eyes, but it two pupils and two retinas in esch. It evolved to hunt by the water surface, catching prey from both above and below. Where there is an evolutionary pressure, there is a way to evolve. This fish proves that what you want is possible. However, do notice that this fish evolved multiple pupils because ...

Yes, this is possible and in fact already happens in humans causing apparent infertility in couples (alongside a host of other sexual reproducing organisms). Consider for instance variations in two genes encoding for proteins in the eggcoat, ZP2 and ZP3, and another gene encoding for a sperm protein that latches onto the eggcoat, C4BPA. Each of these three ...

Your worms are ambush predators. They very rarely move. https://www.bbcearth.com/blog/?article=snapping-death-worms-can-hide-undetected-for-years These giant polychaete marine worms (Eunice aphroditois, also known as the sand striker) are real. They lurk, waiting for something to pass by in reach and then they pounce. They get big; at least 3 meters....

If you don't want or can't afford ejecting matter, you are left with solar sail: since photons carry momentum, reflecting photons can allow you to harvest that momentum and use it to move. Expand reflective leaves in a suitable way, and use the light coming from the star at your advantage. Mind of two consequences: If you reflect the photons, you are not ...

There are trees which are capable of killing large animals, in fact, only they don't eat them afterwards. But it's a start. Pisonia brunoniana is known as the birdcatcher tree for a reason. The seed pods of this tree are coated with a mucus which traps insects - even this alone could evolve into carnivory, but wait till you hear what happens next. These ...

It seems to me that your angels wouldn’t be invincible, impossible-to-defeat warriors with the parameters you’ve set. Like other answers have said, since they have to land eventually, they will be vulnerable to the other, larger races in your world. While they would be excellent raiders and quite powerful warriors (a wine skin filled with flammable oil and ...

Because they convert any excess energy directly into mana. As stated they are powerful mages, and as such are deeply linked with magic, and it's fuel, the omnipresent Mana. Thus they - or at least the more magier ones - eat A LOT of calories. It's just converted to astral energy which surrounds them on another plane. Thus they do get fat - just not in this ...

In our world, we do have an animal that habitually violently smashes its head against things at high frequency: the woodpecker. Their heads have multiple adaptations to the repeated stresses caused by pecking, such as: A specific kind of spongy bone structure is lining the skull. It is compressible and most of it is located around the front of the back, ...

Offering a different angle from many of the other answers... Bird people can be fearsome warriors in battle, yes, especially in numbers. But they live much higher than most land-based races, in inaccessible crags and the occasional beautiful high city, the glories of which are rarely seen by land-based races. At 3,800m above sea level, the air temperature ...

It's known as Biomineralization Biomineralization is the formation of complexes containing inorganic materials by living organisms. This occurs in organs as diverse as bone, teeth, egg shells, and invertebrate exoskeletons. Calcium is a very “popular” biomineral, occurring for example, as phosphates in vertebrate skeletons and carbonates in ...

It depends (but probably not). Some forms will be achievable, with more or less difficulty. Any form? No. There are several limitations you did not take away (some of them are discussed in the Sight of Proteus (Behrooz Wolf) series by Charles Sheffield, where an intentional transformation machine, the "form-change vat", is a plot device): conservation of ...

The bullets are made from Adina cordifolia. Adina cordifolia aka Haldina is a decideous tree that grows up to 20 meters (65 feet) high. Haldina cordifolia, syn. Adina cordifolia, is a flowering plant in the family Rubiaceae, the sole species in the genus Haldina. It is native to southern Asia, from India in the east to Yunnan and Vietnam and south ...

Since your angels are light, flying entites, they probably can't carry much. The more they carry, the more slowly and laboriously they fly, and as a result, the better a target they present themselves. This would, naturally, lead to light armor and armaments, think leather armor and your earlier mentioned projectiles - stones, spears, etc. But in order to ...

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 ...

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 ...

They don't value the Gold - They expel it from their burrows What use is a shiny metal to an ant? They don't make artefacts or have currency. They don't have an aesthetic sense apart from food. The ants line their burrows with a sticky substance they produce from their rear ends. Obviously a lump of gold is an obstruction to the building of their ...

Rule 1: Don't feed like a tiger, feed like an alligator. Alligators (and several other animals) eat only rarely: they can sustain themselves on just a single large prey animal every year, or even every two years, because they move slowly and don't use up much energy. Trees are great at moving slowly and conserving energy! That means that your particular ...

The same way a nautilus swims around in water: jet propulsion. Nautiluses move using a hyponome, which expands to pull in water from the sides of the nautilus, and contracts to expel a jet of water. The bio-blimps can majestically wheeze across the land using what is essentially an organic bellows, just like the nautilus. Whenever it wants to move, it ...

Polycephaly is a medical condition, in which an animal has multiple heads. This is a special type of conjoined twin. 2 is the most common form, but there is at least 1 case of 3 heads documented (a turtle). In many cases, each head is capable of sleeping independently of the other, allowing your Biological Creature to function without turpor. In some ...

Agriculture: Goblins can do anything larger animals can't do. It shouldn't be too difficult to teach them to harvest crops, vegetables and fruit, take care of the plants in general, get rid of unwanted weeds, sow seeds etc. They might even lead larger animals for plowing. Manufacturing can also be made easier. If they can clean, anything for textiles for ...
