The “scaly-foot gastropod” is a type of snail that thrives in the hydrothermal vents found deep in the Indian Ocean. And it has a unique property: a magnetic outer shell.
We’ve seen the dramatic white creatures that live around underwater vents in the Earth’s surface. But what about the vents themselves? There’s no “fire” inside them, so what is the black “smoke” pouring out of them?
When it comes to life on Earth, we're not sure if it came from the outside (transported by comets) or on the inside. A new theory focuses on the "interior " theory, saying that microbes could have evolved from non-living matter such as chemical compounds in minerals and gases.
There are plenty of places on Earth that seem alien to us. The deep sea is a perfect example: it's been said that we know more about Mars than we do about the bottom of the ocean.
This is a new low, even for life on Earth — geologists have found bacteria living 1.6 kilometers beneath the ocean floor, twice as deep as ever recorded before. The simple bugs (one cell pictured, at the end of the arrow) are related to the ones found at deep sea hydrothermal vents, but they represent a stunning new…
