Jánoíks

Jánoíks are a fictional species from the Star Trek universe, specifically appearing in the animated series Star Trek: The Animated Series. They are a silicon-based life form encountered by the USS Enterprise in the episode "The Infinite Vulcan." Jánoíks resemble crystalline structures and possess the ability to communicate telepathically. Their physiology is significantly different from carbon-based life, as they do not require air or water to survive. Instead, they draw sustenance from geothermal energy. The Jánoíks are depicted as a peaceful and ancient race, deeply connected to their home planet.

During their encounter, the crew of the Enterprise learns that the Jánoíks are vulnerable to certain sonic frequencies, which can disrupt their crystalline structure. Captain Kirk and his crew work to find a way to protect the Jánoíks from this threat, demonstrating the Star Trek ethos of understanding and protecting alien life. The species' existence highlights the diverse possibilities for life beyond what is commonly understood on Earth, a recurring theme in the Star Trek franchise.
