Unveiling the Underwater Drama: A Crab’s Last Moments Before Becoming Cuttlefish Dinner

In May 2023, Matteo Santon, a marine visual ecologist at Bristol University, was diving in Indonesia to study cuttlefish. His goal was to see these fascinating creatures hunt, but he wanted to do it from the crab’s point of view—not just as an observer.

During his dives, he captured more than 200 cuttlefish hunts, finding that the cuttlefish employed some remarkable hunting techniques. Dr. Santon was amazed by their hunting displays, saying, “The first time I saw these hunting displays, it was probably one of the coolest things I’ve ever seen.”

In a recent study published in the journal Ecology, Santon and his team noted that cuttlefish use four different body patterns when hunting. Some of these patterns resemble drifting leaves or corals, cleverly designed to trick their prey. This camouflage may disrupt how crabs see them, making them appear harmless or even invisible.

Cuttlefish are skilled at deception. Like octopuses, they have special skin cells filled with pigments. This allows them to change their color and texture instantly. They can blend into the seafloor or disguise themselves as rocks or algae. While researchers have studied their hunting behavior in labs, examining it in the wild provides new insights into how they adapt and survive.

The work by Santon and his team sheds light on the fascinating tactics these sea creatures use to thrive in their underwater environment. By diving into their world, we gain a deeper understanding of the cuttlefish and the incredible strategies they employ to hunt.
