The strawberry squid (Histioteuthis heteropsis) has one big eye and one small eye. Together, this improbable pair helps the squid hunt for food in the ocean’s twilight zone. The big left eye looks upward to spot shadows cast by prey in the dimly lit waters above. The eye’s tubular shape helps collect as much downwelling light as possible. Often, this eye has a yellow lens to see through the luminescent camouflage of its prey. The squid’s right eye is small and looks downward. This eye searches for flashes of bioluminescence produced by prey or predators lurking in the darker waters below. This squid is sometimes called the cockeyed squid for the remarkable difference in size between the two eyes.
