The Strawberry Squid: A Master of Adaptation in the Deep Ocean
Summary
In this article, we explore the fascinating adaptation of the strawberry squid, which has one small eye and one large eye, and how this helps it hunt for food both above and below it in the deep ocean. We also look at the squid’s bioluminescent pits, which emit light and help it blend in with the surrounding environment.

The Asymmetrical Face of the Strawberry Squid
The strawberry squid is known for its unique facial features, which include one small eye and one large eye. While this may seem strange, it is actually a brilliant adaptation to life in the deep ocean. The squid needs to be able to hunt for food both above and below it, and having one eye that is better suited for each task allows it to do so efficiently.
The Big Eye: Scanning for Prey from Above
The larger eye of the strawberry squid is used to scan for creatures casting silhouettes against the dim blue light filtering down from the surface of the water. This allows the squid to hunt for prey that is swimming above it.
The Tiny Eye: Hunting for Bioluminescent Prey Below
The smaller eye of the strawberry squid is used to hunt for critters using bioluminescence to communicate. This is important because many of the squid’s prey use counter-illumination, which makes them blend in with the surrounding environment. By using its small eye to search for bioluminescent prey, the strawberry squid is able to find food that other predators might miss.
Bioluminescent Pits: Emitting Light for Camouflage
The strawberry squid has pits on its body that make it look like a strawberry, but these pits actually emit light. By firing up these pits on its underside, the squid can match the light coming from above, making it nearly invisible to anything watching below. This is known as counter-illumination, and it is a common tactic used by many deep-sea creatures.
The All-Seeing Eye of the Deep
While the strawberry squid’s unique facial features and bioluminescent pits make it a master of adaptation in the deep ocean, it is not invincible. Prey that use counter-illumination can still spot the squid if its glow is too green compared to the blue light above. However, the squid’s large eye absorbs more blue light, making it less noticeable to prey. In this way, the strawberry squid is able to use its all-seeing eye to hunt for food and avoid becoming prey itself.
Conclusion
The strawberry squid is a fascinating creature that has adapted to life in the deep ocean in unique and interesting ways. Its asymmetrical face, bioluminescent pits, and all-seeing eye make it a master of camouflage and a formidable predator in its environment. By studying creatures like the strawberry squid, we can learn more about the incredible diversity of life on our planet and the many ways in which organisms have evolved to survive and thrive in even the harshest of environments.
