Many of the animals found in the twilight zone have adapted to the dim light in one way or another. It is likewise for cock-eyes squid with its dimorphic eyes. One eye is almost twice as big as the other, which is not a coincidence. The bigger eyecatches shadow from being above it, whilst the little eye tracks bioluminescence from creatures underneath, making their bodies preferred horizontally rather than vertically. The photophores scattered around the body have two functions; concealing and counter-illumination. Silhouettes of marine animals appear darker when seen from underneath with the light coming from above, making counter-illumination an effective camouflage method for the squid while also being effective against predators to avoid certain doom.
