The darkest depths
Deep in the ocean, further than anyone wearing our swimsuits has gone, lies a different world. In the pitch black, 1,000 - 6,000 meters below the surface, light can be a blessing or a curse, and it makes all the difference to the squids that live here. Their bioluminescence protects them, attracts their prey, and helps them find mates. For the squid, light is a 1-stop-shop.
