Ancient Lava Caves in Hawai'i Are Teeming With Mysterious Life Forms

Microbes are the smallest known living organisms on Earth and can be found just about everywhere, even in the cold, Mars-like conditions of lava caves.

On the island of Hawai'i, scientists recently found a marvelous assortment of novel microbes thriving in geothermal caves, lava tubes, and volcanic vents.

These underground structures were formed 65 and 800 years ago and receive little to no sunlight. They can also harbor toxic minerals and gases. Yet microbial mats are a common feature of Hawai'ian lava caves.

Samples of these mats, taken between 2006 and 2009 and then again between 2017 and 2019, reveal even more unique life forms than expected. When researchers sequenced 70 samples for a single RNA gene, commonly used for identifying microbial diversity and abundance, they could not match any results to known genuses or species, at least not with high confidence.

Diversity among the sites varied. Older lava tubes, those between 500 and 800 years old, hosted more diverse microbe populations than geothermically active sites or were less than 400 years old.

I'm sorry you feel that way. But I speak 'n' spell American, and we spell it Hawaii. When it comes to all things Hawaiian, I'm going to have to appeal to Steve McGarrett, my authority on these matters. Steve always says "Hawaii". No exceptions.

“Excuse me, sir, my wife and I are having an argument, She says it’s pronounced ‘Ha-way-ee’ and I say it’s pronounced “Hav-ay-yee”, how do you pronounce it?”

“It’s pronounced ‘Hav-ay-yee’.”

“Thank you!”

“You’re velcome!”
