!!Stock Explanations for Addressing This Subject:

It's rare to see anyone [[ElephantInTheLivingRoom actually address the subject onscreen]], but if the matter ''does'' come up, expect to see one of these [[HandWave stock explanations]]:
* The genitalia of some creatures (e.g., reptiles, amphibians, fish, monotreme mammals, and birds) just aren't externally visible to begin with.
* Even when they are, these "attributes" might be ''so'' alien that we humans [[WeirdnessCensor wouldn't recognize them as such anyway]].
* Some creatures have external genitalia, but they are not conspicuous (e.g., cats, rabbits, guinea pigs, and beavers) and are at least somewhat easy to avoid noticing in RealLife.
* Some creatures (e.g., sponges, even frogs and toads) just don't have any genitals to begin with. For this explanation, please just list aversions (inversions in their case) and lampshades as animals correctly lacking genitals are Administrivia/PeopleSitOnChairs.
* Some forms of life are so alien that they may not even need to have such anatomy in the first place.
* The details are logically present, but are obscured beneath a layer of body fur or other BizarreAlienBiology.

The last explanation is probably the most common assumption, even though it's not true to RealLife observation. With many mammals, the body pelage (covering of fur or hair) is actually thinner around the genital and anal area (to avoid getting it soiled when nature calls). The human is an exception to this rule as the hair around the genitals (or pubic hair) is thicker, but it doesn't hide male human genitalia. The human anus may not be seen easily due to the way the butt is shaped, but many mammals, like dogs and skunks, have an anus that would be seen easily in real life. Also many mammals don't have a thick enough coat to adequately conceal their genitalia and anus in the first place. The male pig, for example, has a rather prominent pair of features on its underside that are hard to ''avoid'' noticing in RealLife, even though the fictional male pig never has them.

!!How The Anus is Rendered if it is Shown:
In anime/manga, comics and 2D animated cartoons, if the anus is shown, it is often drawn as looking like the letter "x", the character "*", or simply a dot.
