By carrying out a quantitative evaluation of appearances of the shadow reflex, we obtained a spectral dependence of skin light sensitivity of immature specimens of Lymnaea stagnalis L. We performed experiments on juvenile specimens with a maximum shell size of 15 mm, to rule out the influence of the sexual dominant on the appearance of the reflex response. With its maximum at 490 nm, the obtained dependence apparently corresponds to the absorption spectrum of the photosensitive skin pigment. 1....

Comparative research on spectral dependence between the appearance of shadow defensive reflex in intact and eyeless adults of Lymnaea stagnalis proved the excitatory role of dermal photoreception and the inhibitory role of the ocular one. The shape of the curve and the modified spectral maximum of the absorption of dermal light-sensitive pigment (490 nanometers) allow the authors to suppose the presence of rhodopsin-like pigment in dermal photoreceptors. 1.

This research contributes to the study of colour terms as a cognitive phenomenon. Since colour is not a universal concept and an ordinary mind does not perceive colour separately from the object, it is possible to observe the knowledge about colour, which exists in the lan­guage but does not exist in its physical sense. We hold that the given knowledge is the cause of significant difficulties arising in the translation of various colour terms, though the nature of these terms existence should not...
