This is the nth time I'm using this image on the site. I could not find a specific question to point you to though. Just remember that the square-cube law is a cruel mistress: every time your creature height or length doubles, if other measures scale proportionally then its surface area quadruples and it volume increases 8x. Even when they are able to stand, ...

Different swallowing techniques: Strong throat muscles: Once getting food between the jaws, stick your neck up allowing gravity to throw your food into your gullet, at which point the throat muscles take action and crush the food for you. No tongue! Sublimation: I don't think this exists on Earth, but acids inside the creature's mouth turn the food into a ...

demigods birthed by goddesses are brought to the heaven/Olympus/magical wherever, because they are in the womb, and therefore reach their full powers quickly, and are well trained. The ones sired by males are left on earth and think they are human. if they do discover their powers it is by accident. they are less powerful on average, because they are ...

I'll suggest something a little like the wonderful 60s project, the paracone. A re-entry system with no parachute, no landing rockets, no wings and no moving parts. The shape-holding structural elements aren't even rigid initially... you pump them up with some suitable gas. The payload is injected into a re-entry trajectory, and then the heat shield is ...

Let's make some assumptions on the shape of our animal first: It is roughly mountain shaped, so a flat cone. To get a good base area, it's radius is about 3 times its height. It propells itself over the frozen wastes by resing on a hard shell of bone on the underside, using stumpy appendages to push itself over flat, frozen land at almost glacial speed. It ...

Mostly My first instinct is to say that this is totally plausible and just a reskinned dinosaur. Except, it's not. If you take a look at the Goliath's muscle structure around the chest and pectoral region, it's clearly based off a human's physique and a bodybuilder's one at that. So let's get something out of the way - 60 feet bipedal creatures do not exist ...

I see two issues here. First, the transition to mobility would be tricky. Plants already spread their seeds wide pretty far just using simple mechanisms and wind power. Why doesn't that work in your world? The next would be that it seems somewhat likely that intelligence at least partly stems from the need to outsmart your prey. You'd have the same issue ...

Parasitism ≠ Symbiosis TL;DR Living creatures that support whole ecosystems of parasites and decomposers would evolve better mechanisms to protect themselves unless those ecosystems provided benefits. Appearance and Behaviors Humanoids 6-9 feet tall Plague doctor mask heads Plantoids First off, we can justify such extreme humanoid heights by having your ...

The shell needs to absorb 9.6j/s (9.6 Watts) of heat energy over that 2 second period. ... but how heating and cooling will wear on the shell are my key concerns. Calcite specific heat capacity: 0.8343 J/g*K So a max of 20J for those 2 secs? At that energy as heat, a 200g (a tenth of those 2kg) mass of calcite will heat up by: 20/(200*0.8343) = 0.12K. ...

There are colonial prokaryotes. source . Used with permission. Nostoc (aka star jelly) is a colonial cyanobacteria. They get as big as small plants. The component cells are held together by matrix they secrete. There must be some sort of communication between them to organize the shape of the colony. I like Nostoc because of the possibility that it ...

Anything is possible really, it just takes time and must yield an advantage along the way. What you're describing is essentially (over many generations) the following sequence: slow, shortening of neck disappearing of the neck altogether, with head now blended on top of body slow bending of spinal column within the body, such that the skull starts to ...

As any mechanical designer knows, if you want to increase the frequency of an oscillatory motion, you need to reduce the oscillating masses. This is why the hummingbird is to little: with bigger masses in its wings, it could not be capable of flipping them back and forth as it does. Since the bio-mechanics you want to emulate is that one, the only way is ...

If done safely/hygenically, you could pierce nearly anything without organs in it. If I see your pictures, the first thing I would think is pierced gills. Very possible, but it would have a massive drawback on underwater breathing. But people have lip tunnels which have any liquid they drink pour straight out. Where there is a will, there is a way. Of ...

I would use the camel as template. The guy stores fat on its emblematic upper back "breast" and when the body needs water, it breaks down the fat to produce water. Say you approach these species as adapted to produce a reserve, increasing the fat/oil reservoir size.The act of lactating could be done away from away from food on weeks long trips. In our ...

When you talk about contamination, are you speaking about biological contamination, or cultural contamination? As far as biological contamination goes, it should be fairly simple for any human society advanced enough for space travel, just make sure that any exits out to the planet's surface (through buildings or out of ships) are kept behind airlocks with ...

There are several possible solutions to this if you think about it. The tongue is used to manipulate food in your mouth. It isn't 100% there to shove it down your throat. On example would be birds. Birds often have fairly fixed tongues. They don't usually go outside of the mouth and have small upwards and downwards movements. In this case, you can see ...

This greatly depends on what you define as consciousness. Do you need to have full body to be a consciousness? Do you need to have a physical brain? What do you need to have to be a conscious being? So I'm going to get technical here - neural networks. A definition from the interwebs is as follows: Neural networks are a set of algorithms, modeled ...

Fungal jellyfish balloons These creatures are plausible. Difficult to justify evolutionarily, but plausible. Let's break it down. Buoyancy: Hydrogen bladders the atmosphere and planetary pressures confine the scientist to ships and droids... The species look like yellow soft orbs, seemingly capable of floating... using a specially evolved Buoyancy organ....

You're looking for photosynthetic slime molds on a primordial world. The colonies need to be smaller. The most glaring issue with this colony is its sheer size. Even alien amoebas need to eat - but if they take up 75% of the planet's surface, chances are they won't leave much room for prey, or nutrients, or much of anything. Even though many colony-forming ...

I’m going to assume that the blood in the lakes and rivers is only red blood cells. White blood cells wouldn’t survive in the open as there would be unlimited bacteria/viruses to fight against. Blood will naturally latch onto oxygen that’s in the air and carry the oxygen with it. That’s what blood does. Note that blood deeply submerged in a lake would not ...

Very difficult if you were there, possible if you weren't Contamination can occur in many ways. Through our biology, through interaction, and through detection. Through Fungal Spores and Bacteria Probably the best known and most obvious one is biological contamination, being transmission of bacteria and fungal spores. The unfortunate thing is, it is ...

See the Portuguese man o' war's structure Being a colonial siphonophore, the Portuguese man o' war is composed of three types of medusoids (gonophores, siphosomal nectophores, and vestigial siphosomal nectophores) and four types of polypoids (free gastrozooids, gastrozooids with tentacles, gonozooids, and gonopalpons), grouped into cormidia beneath the ...

You only need a mobile seed, what evolutionary advantage being a "sentient seed" brings into the picture? Maybe if you add a parasitic component to it, like immobilize/kill some animal and bring the body into an appropriate place before seeding it? At least this way some elements of world perception and tactics may be necessary. Another problem: "sentient" ...

If the universe is populated as you suggest, then it is possible, but begs the question why If civilisations elsewhere exist, they are more likely to be much further advanced or not advanced than us, than they are similar to us. In actual fact, it could be likely that they are so much more advanced that they may not even notice us, like we don't tend to ...

Alternative 1, with the twist: bio-luminescent organ is skin! Well, not all skin. Belly skin. Some skin on the belly is different. We are talking hormonal changes which happen during male puberty which allow human males to grow beards and whiskers. On the other hand, you do not grow beard on your feet, do you? Instead of hair follicles growing, you have ...

Tzeench must be optimized to support the Great Plan Appearance I won't address a lot of the cosmetic changes like "short stubby faces," "blue skin" or "three toes" because I'm assuming these are all possible evolutionarily. No eyes This is plausible, but what's the alternative? Do these creatures use echolocation, or do they sense infrared radiation ...

You're not going to wind up with anything like a dragon because the square-cube law is a harsh mistress, but if you're creative you might be able to make a giant creature, of sorts. The square-cube law is a lot less problematic if your creature is relatively flat, and no single part of it is unreasonably thick. Say, for instance, a giant starfish-like ...

Various prey and predators or fighting eachother I see no reason this creature couldn't exist as there are hundreds of examples of real creatures that have developed similar traits, even if not necessarily all of them. Therefore there is no reason they wouldn't have other related personality traits. Preying mantis will sit perfectly still among leaves, ...

The first step would probably be to form something akin of a biofilm: a community of unicellular organisms thriving in the same environment. The next step would be a separation of roles and tasks: some of them on the outside could specialize in protecting/shielding those inside, some other could specialize in digesting nutrients for the rest of the ...

You've basically provided the answer in your own question under the extra facts. The life co-existing on this creature's home world is dangerous. So given sufficient intellect, who controls the sky, control the world. They can take refuge in arboreal communities or settle in places inaccessible by those tied to the ground. Avoiding competition permits ...
