The colouration and its behavioural significance in the corkwing wrasse, Crenilabrus melops
The colour patterns of the corkwing wrasse Crenilabrus melops and the functional significance of these patterns has been described. The resting colours of the fish are described for juveniles, matureExpand
The ethology of Labroides dimidiatus (cuv. & val.) (Labridae, Pisces) on Aldabra
A small group of Labroides dimidiatus were studied over a period of 4 months in the shallow reef environment of Aldabra. It was found necessary to redefine the concept of a cleaning station.Expand
Cleaning symbiosis among British fish with special reference to Crenilabrus melops (Labridae)
Three new examples of cleaning symbiosis are recorded among the British labridae, Crenilabrus melops, Ctenolabrus rupestris and Centrolabrus exoletus . The first two have only been seen in aquariaExpand
The diet of the two-spot goby, Gobiusculus flavescens (Pisces)
Juvenile and adult two-spot gobies were collected at three sites in the Plymouth area: the Plymouth Breakwater, Fort Bovisand, and the Yealm estuary from early June until the end of September 1987. Expand
Defensive behaviour of sea anemones in response to predation by the opisthobranch mollusc Aeolidia papillosa (L.)
Evidence is presented which suggests that acontia have some deterrent effect on this predator, and most acontian anemones are probably able to move by pedal locomotion and to detach from the substrate, much less frequently given than by Actinia equina. Expand
The Anatomy of Respiratory Structures in the Dorid Nudibranchs, Onchidoris Bilamellata and Archidoris Pseudoargus , With Details Of The Epidermal Glands
The respiratory function of the naked body of sea slugs (Opisthobranchia) has long been recognized and histological details, but do not seriously add to the understanding of the function of dorid gills or their circulation system. Expand
Spectral absorbance changes in the violet/blue sensitive cones of the juvenile pollack,Pollachius pollachius
SummaryUsing the technique of microspectrophotometry (MSP) we have found that the short wavelength sensitive cones in the retina of the pollack (Pollachius pollachius) shift in spectral absorptionExpand
