The biology of deep-sea life
Welcome! I'm so excited to explore the mysteries of the deep sea with you. It's one of the most fascinating, alien, and unexplored places on our planet.
Before we dive into the pitch-black depths, I'd love to know a bit more about you. What is your background in biology or oceanography, and what specifically sparked your curiosity about the deep ocean?
I have some science background and want to understand the extreme physics and chemistry.
It is great to have you here! Since you have a background in science and a keen interest in physics and chemistry, we are going to dive straight into the brutal physical boundaries of the deep ocean.

The Boundaries of the Deep Sea
To understand the biology of this alien world, we first have to draw its physical borders. Oceanographers generally define the deep sea as anything starting below 200 meters (about 656 feet) from the surface, according to the . This depth marks a profound transition zone where the ocean gets rapidly colder, darker, and more pressurized.
