How To Kill SaucebacksSome Sagan 4 organisms are a little bit different from the animals we're familiar with on Earth--all their body parts are in different places, and in some cases basic strategies like strangulation don't seem to work at all.
This can make creating carnivores and armored species difficult, as it's unclear what to attack or defend, respectively. So today, I will list various ways to kill
saucebacks.
Taking a Look at Sauceback Anatomy


Saucebacks are a great example of a group of organisms that many normal strategies won't work on. You could still probably make them bleed out, sure, but there's no windpipe to crush, the brain is well-protected, and with the brain's odd position there's probably not an easy-to-access jugular equivalent to bite into.
But there are still ways to kill them.
FasterThe fastest way to kill a sauceback is to destroy the brain. This can be done with a powerful strike from above, either smashing it directly, or concussing it so badly that it turns into mush. The
ascendophrey uses this strategy, stomping the brains of other flying saucebacks from above.
But while this is fast, it is not very easy, as it requires getting directly above the sauceback and using a lot of force; the ascendophrey is able to accomplish it because its prey can fly, so it won't hit the ground and shatter its legs immediately afterwards.
A sauceback is immediately doomed and dies of asphyxiation when the base of its tail is broken. Breaking one of the first 4 caudal vertebrae will paralyze some or all of the lungs, thus causing it to suffocate. Predators can aim a bone-crushing bite to the base of the tail to accomplish this.
If the attack is aimed too far along the tail, however, not all the lungs will be affected and the sauceback can escape and heal--after kicking its attacker to death, of course.
SlowerA sauceback can be disemboweled by slicing or tearing its chest, as the digestive system is in the font. This requires getting through the gastralia, however.
This does not work on flying saucebacks, as their keel protects the chest.
CruelA sauceback with a broken leg cannot walk, and will likely starve to death. This is because saucebacks are obligate bipeds, and it is true of flightless birds such as ostriches as well. However,
a social sauceback can survive such an injury if it has a pack to care for it.
A sauceback with a broken neck cannot see or move its mouth and therefore cannot feed itself, and will starve. In some cases a pack might still be able to take care of it, but without the ability to swallow on its own, it will still struggle to eat.
A powerful strike to the chest can rupture a sauceback's intestines. If it does not die of internal bleeding, infection from its own gut microbes will leave a sauceback to die a slow and painful death.
Non-FatalIn the case of defense, an organism might just want to stop a sauceback that's attacking them rather than spend time and energy killing it.
Suddenly yanking the tail can knock the wind out of a sauceback. This is because the lungs are contained in the tail. This can be compared to punching someone in the chest or throat.
Striking a sauceback on the "sauce" or right above the legs can stun it. This is because this is where the brain is, similar to knocking someone on the head.
