...L. M. Mäthger; E. J. Denton SUMMARY Observations were made of the reflective properties of the iridophore stripes of the squid Alloteuthis subulata and Loligo vulgaris , and the likely functions of these stripes are considered in terms of concealment and signalling. In both species, the mantle...

...J. B. Messenger; C. J. Cornwell; C. M. Reed ABSTRACT Colour changes in cephalopods are controlled by complex organs termed chromatophores whose radial muscles are directly innervated from the brain. In the squids Alloteuthis subulata and Loligo vulgaris , light microscopy of silver- or Methylene...

...Candida M. Reed ABSTRACT Dye coupling between the cone-shaped radial muscle fibres, which control the expansion and closing of a squid chromatophore organ, was investigated in the squid Loligo vulgaris. Particular attention was paid to the role of the myomuscular junctions located between...
