Pacific Hatchet Fish

Argyropelecus affinis

Pacific Hatchet Fish

Flattened side to side like a hatchet blade, this silver deep sea fish points rows of downward glowing organs into the dark to erase its own shadow from below. It lives in the mid water around three hundred to six hundred metres, making short daily rises, and feeds on copepods, krill and other small drifters.
