Mechanism of reflexion in silvery layers of fish and cephalopods
Qualitative observations on scales from herring and from other regions on the sprat supported the hypothesis that their guanine crystals were also arranged approximately in ¼λ0 stacks, and conclusions were reached for coloured surfaces found in the skin of the horse mackerel, the iris of the neon tetra, the reflecting tapeta of the dogfish and the spurdog.
Sound and Startle Responses in Herring Shoals
The behavioural experiments described in this paper were carried out to complement earlier physiological work on the acoustico-lateralis system of the clupeid fishes and suggested that the signals arising from the inner ear and the neuromasts of the lateral line are used in conjunction to provide information about direction and range.

It is illustrated how structural coloration contributes to the overall appearance of the cephalopods during intra- and interspecific behavioural interactions including camouflage.
The Buoyancy of the Cuttlefish, Sepia Officinalis (L.)
The excess weight in sea water of the living tissues of Sepia officinalis (L.) is approximately balanced by the cuttlebone, which accounts for about 9·3% of the animal's volume. The density of…
Mechanical factors in the excitation of clupeid lateral lines
It is estimated that the sprat lateral line system excited in this way could detect a neighbouring fish in a school at distances of up to a few fish lengths and so estimated the effective stimulus to different parts of the lateral lineSystem.

The organization of these crystals is described for the silvery surfaces of bony fish, the herring and mackerel, for the reflecting tapeta found in the shark and dogfish, For the photophores of the deep-sea hatchet fish and for the eye of the scallop.

It is shown that animals that can emit and are sensitive to such far-red light will have very great advantages in being able to see without being seen and the intensities of penetrating daylight are such that visual acuity could be fairly good down to considerable depths in the mesopelagic zone.
On the use of ammonium for buoyancy in squids
Squids (teuthoids) fall into two distinct groups according to their density in sea water. Squids of one group are considerably denser than sea water and must swim to stop sinking; squids in the other…

Genotype-dependent changes in whole-body protein turnover are shown to be of significance to metabolic efficiency, energetic maintenance requirements and associated rates of dietary absorption in Mytilus edulis, and proposed as a mechanism by which genotype may mediate intraspecific variations of growth among animals generally.
Mechanical Factors in the Excitation of the Lateral Lines of Fishes
The effective stimulus to a neuromast lying inside a typical lateral line system will be one that produces a movement of the cupula of the neuromast relative to the wall of the lateral line canal.…
