The organization, ultrastructure, growth, and development of two types of cuticular photophore in oplophorid shrimps (Oplophorus spinosus and Sys- tellaspis debilis) are described. Photophores located in the third maxilliped consist of a unit structu

We present the results of the first quantitative, whole-lifespan study of the relationship between age-specific neurolipofuscin concentration and natural mortality rate in any organism. In a convenient laboratory animal, the African migratory locust,

The prospect of removing cellular deposits of lipofuscin is of considerable interest because they may contribute to age related functional decline and disease. Here, we use a decapod crustacean model to circumvent a number of problems inherent in pre

Interspecific variations in rhabdom structure between various oplophorid shrimps are described and the differences are related to the light environment at different depths within the mesopelagic zone. The ultrastructure of the distal rhabdom in these

Use of the lipofuscin ageing method as a crustacean fisheries research tool requires a calibration of tissue lipofuscin concentration to chronological age that is applicable to the natural population under investigation. Current approaches, involving

The spectral sensitivities of five species of decapod crustaceans have been determined by electroretinogram measurements. Their spectral sensitivities conform to the general picture for marine crustacea with high sensitivity to blue-green wavelengths

The structure and optics of the mesopelagic double-eyed mysid crustacean Euchaetomera typica Sars, 1884 are described for the first time. The lateral eye is a typical refracting superposition eye with a wide field of view (172°) and low resolution (

Temporal responses of eyes from four decapod species taken from sublittoral (Pandalus montagui Leach), coastal [Nephrops norvegicus (L.)] and deep-sea [Paromola cuvieri (Risso) and Chaceon (=Geryon) affinis A. Milne Edwards and Bouvier] habitats were

The long-term survival and growth of Norway lobsters, Nephrops norvegicus (L.), were examined in relation to light-induced retina breakdown. The incidence of eye damage was first assessed in tagged N. norvegicus released in Loch Torridon, on the west

The natural rate of lipofuscin accumulation in an eyestalk ganglion was determined from microtagged European lobsters, Homarus gammarus, of known age, recaptured from the Yorkshire fishery (United Kingdom). This calibration, in combination with suppo
