Unlike many of the land-based creatures, it feels like we’ve barely scratched the surface when it comes to how many breeds of fish or other marine animals dwell in the murky depths of our oceans, rivers, lakes, and other bodies of water.
In 2017, there were seven new breeds of fish discovered, one of which was the Mariana Trench dwelling Pseudoliparis Swirei (or Snailfish of the Deep for us land lovers). Looking like a rather large tadpole, these little guys have milky white skin that is so translucent that you can see some of their internal organs without much effort. On top of which, this creature has earned the title of deepest living fish, with almost 8,000 meters beneath the surface being the number to beat to steal the title. Scientists are skeptical if it will ever be surpassed, because the water pressure may be too great to thrive. But who knows? Maybe there will be another fish or critter that swims its way into the fray!
