Common housecats have a mutualistic symbiotic relationship with the parasite Toxoplasma Gondii. When it infects rodents (usually spread from cat Feces), it removes their fear of cats and even causes them to seek out cats. The cats can then easily eat the rodents, finishing the life cycle of the parasite. While this is not a chemical compound, it is a real-...

Perhaps this creature uses hallucinogens? Cannabis can cause depersonation/derealization (see https://americanaddictioncenters.org/dissociative-disorders/depersonalization-drug-abuse for a description of this disorder) and furthermore, cannabis can be extracted using alcohol, which is used to make perfume. Now, perfumer's alcohol is made of three things: ...

There are substances called getters which are used to absorb volatile elements in sealed vacuum chambers, which, for obvious reasons, cannot be pumped down more than once. For example they were used in CRTs. A getter is a deposit of reactive material that is placed inside a vacuum system, for the purpose of completing and maintaining the vacuum. When gas ...

All prior answers suggest the direct route of materials with high strength. I suggest an alternate solution, based on inertia. Any projectile has a certain mass, and it imparts momentum from that mass onto its target upon impact— No matter how fast it's going, it can only penetrate so far before it's shed enough of its momentum into the struck material that ...

A rigid swim bladder would do the trick Fish already have an organ that allows them to control their floatation called a swim bladder. In fish, it's basically a ballon, but if the bladder covered bone with only a small opening, it would likely be able to hold a low-pressure region relative to the outside. Mythbusters tested if you could cause a container ...

It might work well! I initially thought - no way. This molecule is for cold blooded creatures living in low oxygen environments. It is going to be burnt by our high O2 environment and will not deliver O2 adequate for our hot muscles. To my surprise I found a bunch of stuff about using hemerythrin as a blood substitute! Towards the Development of Hemerythrin-...

The photosynthesis process doesn't change — cell resiliency and water do Photosynthesis is merely the process of converting electromagnetic radiation into sugar. Plants favor the blue-green spectrum of visible light because it packs a lot of energy and abundantly passes through everything from the Van Allen radiation belts to the atmosphere to reach ...

Melanized fungi manage the trick of radiosynthesis, to the point where their attenuation of gamma radiation is such that they're being considered (as in the linked paper) for biological spacecraft shielding. Specifically, Cladosporium sphaerospermum is a relatively commonplace fungus that manages the trick. So it wouldn't be "photosynthetic life", ...

Maybe start looking for special chemical process that will differ from what we have on earth, and try to use it in some situation. For example, find a material the reacts with silicon but not with carbon and use it to harm the alien or something like that. Another option could be tell in a more subtle way, like having a silicon alien calling a human a ...
