Yes. If your not looking for intelligent life, there are "extremophilie" organism that can survive intense pressures and temperature. These microbial critters can survive in nearly any environment imaginable. Including hitching a ride in on an asteroid. Some theories even say life on this planet was seeded from outer space by hitchhiking in on asteroids.
Now if your looking for something a little more evolved, then the answer is still yes. We are discovering new species at the bottom of the ocean all the time. In places were light from the sun never reaches (underground caverns) are strange, opaque, bioluminescent fish. (They glow in the dark)
The world underneath our oceans is so vast, and we have only explored a small fraction of it. Indeed we have explored more and know more about outer space than we do about the world beneath our own oceans.
After decades of searching scientists have discovered that a vast reservoir of water, enough to fill the Earth’s oceans three times over, may be trapped hundreds of miles beneath the surface, potentially transforming our understanding of how the planet was formed.
The water is locked up in a mineral called ringwoodite about 660km (400 miles) beneath the crust of the Earth, researchers say. Geophysicist Steve Jacobsen from Northwestern University in the US co-authored the study published in the journal Science and said the discovery suggested Earth’s water may have come from within, driven to the surface by geological activity, rather than being deposited by icy comets hitting the forming planet as held by the prevailing theories.
