Cuttlefish Sepia officinalis Preferentially Respond to Bottom Rather than Side Stimuli When Not Allowed Adjacent to Tank Walls. [PDF]
PLoS ONE, 2015 Cuttlefish are cephalopods capable of rapid camouflage responses to visual stimuli. However, it is not always clear to what these animals are responding.

Control of zootechnology leads to improved Cuttlefish (Sepia officinalis, L.) reproduction performance up to pre-industrial levels [PDF]
, 2020 Cephalopods are gaining momentum as an alternate group for aquaculture species diversification, not only because they are a good food source (highly appreciated in some worldwide markets) but they also have the potential to quickly reach a market size ...

Sperm displacement behavior of the cuttlefish Sepia esculenta (Cephalopoda: Sepiidae) [PDF]
, 2005 Sperm displacement behavior of cuttlefish (Sepia esculenta) was observed in a tank. Before ejaculation, male cuttlefish used their arms III to scrape out sperm masses attached to the buccal membranes of females. The removed sperm mass debris was directly

Elemental Ratios in Cuttlebone Indicate Growth Rates in the Cuttlefish Sepia pharaonis
Frontiers in Marine Science, 2020 Cuttlebone is a hard calcified structure that supports the cuttlefish body and aids in the regulation of buoyancy. The calcification rate of cuttlebone is high and is close to the growth rate of the cuttlefish mantle.

A Migration-Based Cuttlefish Algorithm With Short-Term Memory for Optimization Problems
IEEE Access, 2020 Cuttlefish algorithm (CFA) is a metaheuristic bio-inspired algorithm that mimics the color-changing behavior by the cuttlefish. It is produced by light reflected from different layers of cells and involves two processes, i.e., reflection and visibility ...

Early Exposure to Water Turbidity Affects Visual Capacities in Cuttlefish (Sepia officinalis)
Frontiers in Physiology, 2021 In La Manche (English Channel) the level of turbidity changes, not only seasonally and daily in seawater but also along the coast. As a consequence, vision in marine species is limited when based only on contrast-intensity.

The effect of unexpected rewards on decision making in cuttlefish
Scientific Reports, 2022 Despite numerous studies demonstrating the cognitive ability of cephalopods, there is currently no study showing an emotion-like behavior in this group of animals.

Learned valuation during forage decision-making in cuttlefish [PDF]
Royal Society Open Science, 2020 Decision-making, when humans and other animals choose between two options, is not always based on the absolute values of the options but can also depend on their relative values.

The brain structure and the neural network features of the diurnal cuttlefish Sepia plangon
iScience, 2023 Summary: Cuttlefish are known for their rapid changes of appearance enabling camouflage and con-specific communication for mating or agonistic display. However, interpretation of their sophisticated behaviors and responsible brain areas is based on the ...
