Microstructural and biochemical characterization of the nanoporous sucker rings from Dosidicus gigas
Recent interest in the development of environmentally benign routes to the synthesis of novel multifunctional materials has resulted in numerous investigations into structure-function relationships of a wide range of ...
Biological versus electronic adaptive coloration : how can one inform the other?
Adaptive reflective surfaces have been a challenge for both electronic paper (e-Paper) and biological organisms. Multiple colours, contrast, polarization, reflectance, diffusivity and texture must all be controlled ...
Dynamic masquerade with morphing 3D skin in cuttlefish
Masquerade is a defence tactic in which a prey resembles an inedible or inanimate object thus causing predators to misclassify it. Most masquerade colour patterns are static although some species adopt postures or behaviours ...
Dramatic fighting by male cuttlefish for a female mate
(University of Chicago Press, 2017-05-02)
Male cuttlefish compete for females with a repertoire of visually dramatic behaviors. Laboratory experiments have explored this system in Sepia officinalis, but corroborative field data have eluded collection attempts by ...
Primary and secondary defences of squid to cruising and ambush fish predators : variable tactics and their survival value
Longfin squid (Loligo pealeii) were exposed to two predators, bluefish (Pomatomus saltatrix) and summer flounder (Paralichthys dentatus), representing cruising and ambush foraging tactics, respectively. During 35 trials, ...
To be seen or to hide : visual characteristics of body patterns for camouflage and communication in the Australian giant cuttlefish Sepia apama
(University of Chicago, 2011-04-06)
It might seem obvious that a camouflaged animal must generally match its background whereas to be conspicuous an organism must differ from the background. However, the image parameters (or statistics) that evaluate the ...
Experimental evidence that ovary and oviducal gland extracts influence male agonistic behavior in squids
(Marine Biological Laboratory, 2004-02)
Recent investigations of sensory and behavioral cues that initiate sexual selection processes in the squid Loligo pealeii have determined that egg capsules deposited on the substrate provide a strong visual and chemotactile ...
Lack of growth enhancement by exogenous growth hormone treatment in yellow perch (Perca flavescens) in four separate experiments
The effect of exogenous growth hormone (GH) treatment on the growth of juvenile yellow perch (Perca flavescens) was investigated in four experiments. In the first two experiments, juvenile yellow perch were reared at either ...
