The cuttlefish can use its beak to help subdue prey and to defend itself against predators and rivals by biting. Like cuttlebones, beaks differ among species, and their remains enable scientists ...

The discovery that cuttlefish can pass a self-control test forces scientists to reconsider how intelligence evolves. Until now, impulse control was associated with mammals and birds, species with ...

A new study has suggested a species of marine animal may communicate with each other by waving. Researchers from École Normale Supérieure in France have found evidence of cuttlefish possibly ...

In its research, the team studied four different arm movements in two cuttlefish species, S. officinalis and S. bandensis. The researchers recorded videos of animals signing and played them ...

Two species of cuttlefish, Sepia officinalis and Sepia bandensis—the common cuttlefish and the dwarf cuttlefish—apparently send messages to their peers through movements that resemble a wave.

The smallest of the roughly 120 species of cuttlefish is the 3-inch-long Pfeffer’s flamboyant cuttlefish (Metasepia pfeferi). The tiny cephalopod can change its color and shape to resemble its ...

These pressures are difficult to uncouple because previously studied species face similar socio-ecological challenges. Here, we investigate self-control and learning performance in cuttlefish ...

Because the species Cohen-Bodénès and Neri studied don’t overlap in their geographic ranges and cuttlefish are quite solitary, Lane wonders whether the signals might be used to confuse prey ...

Some male cuttlefish seem to squirt out ink to enhance their courtship displays, offering the first evidence that cephalopod ink has uses beyond just fighting and defence against predators.

Examining genes from squid and cuttlefish, the researchers discovered that these cephalopod species also have modified neurotransmitter receptors in their suckers. But some of the squid and ...

Cultural and linguistics expert Louisa Stoeffler interprets these communication signals from the animals. Two species of cuttlefish, Sepia officinalis and Sepia bandensis—the common cuttlefish and the ...
