Adaptive Coloration in Young Cuttlefish (Sepia Officinalis L.): The Morphology and Development of Body Patterns and Their Relation to Behaviour
Young Sepia officinalis (0-5 months) were studied in the laboratory and in the sea, and their appearance and behaviour compared with that of adult animals, confirming that patterning is neurally controlled and apparently mediated exclusively by the visual system.
Growth, reproduction and life span of Sepia officinalis (Cephalopoda: Mollusca) cultured through seven consecutive generations
Hundreds of Sepia officinalis were hatched and cultured through the life cycle in each of 13 populations, and two genetic lines were maintained: one for an unprecedented seven generations and another presently in its fourth, with a trend towards larger individuals and longer life spans in subsequent generations.
Principal features of the mating system of a large spawning aggregation of the giant Australian cuttlefish Sepiaapama (Mollusca: Cephalopoda)
By aggregating to spawn and spawning asynchronously, females may also increase male–male competition through indirect mate choice and have implications for understanding the species' life history and the impacts of fishing.
Mechanisms and behavioural functions of structural coloration in cephalopods
It is illustrated how structural coloration contributes to the overall appearance of the cephalopods during intra- and interspecific behavioural interactions including camouflage.
Sound detection by the longfin squid (Loligo pealeii) studied with auditory evoked potentials: sensitivity to low-frequency particle motion and not pressure
Both the AEP response characteristics and the range of responses suggest that squid detect sound similarly to most fish, with the statocyst acting as an accelerometer through which squid detect the particle motion component of a sound field.
Effect of temperature on laboratory growth, reproduction and life span of Octopus bimaculoides
Higher temperature accelerated all aspects of reproductive biology and shortened life span by as much as 20% (from approximately 16 to 13 mo).
Maintenance, Rearing, and Culture of Teuthoid and Sepioid Squids
The challenges of collecting, transporting, and maintaining healthy wild squids have been nearly as formidable as those of determining the structure and function of ion channels in squid giant axons, but any improvements in maintenance, rearing or culture will lead to greater availability to meet the demand from researchers, but hopefully to the provision of healthy squids for a wide range of experimentation.

This primer provides an overview of recent work on the mechanisms and principles of rapid adaptive camouflage of cephalopods — octopus, cuttlefish and squids.
Continuum robot arms inspired by cephalopods
In this paper, we describe our recent results in the development of a new class of soft, continuous backbone ("continuum") robot manipulators. Our work is strongly motivated by the dexterous
Color blindness and contrast perception in cuttlefish (Sepia officinalis) determined by a visual sensorimotor assay
It is shown clearly that cuttlefish must be color blind, as they showed non-disruptive coloration on the checkerboards whose color intensities were matched to the Sepia visual system, suggesting that the substrates appeared to their eyes as uniform backgrounds.
