Crustaceans contain a great variety of sensilla along their antennules that enable them to sense both hydrodynamic and chemical stimuli in aquatic environments, and can be used to inspire the design of engineered sensing systems. For example, along the antennule of the freshwater crayfish, Procambarus clarkii, four predominant mechanosensory sensilla morphologies are found. To study their respo...

Near-field disturbances in the water column are known to trigger reflex antennular flicking in the crayfish Procambarus clarkii. We have identified the hydrodynamic sensors on the lateral antennular flagellum that constitute an afferent limb of this reflex and have measured the relative directionally dependent thresholds of the sensory neurons associated with these structures to hydrodynamic st...

Giant interneurones mediate a characteristic `tail ̄ip' escape response of the cray®sh, Procambarus clarkii, which move it rapidly away from the source of stimulation. We have analysed the synaptic connections of proprioceptive sensory neurones with one type of giant interneurone, the lateral giant. Spikes in sensory neurones innervating an exopodite-endopodite chordotonal organ in the tailfan,...

Climate change, such as elevated temperatures, may facilitate biological invasion. Aquatic animal systems are more vulnerable to biological invasion when the temperature rises. Animal personality also plays an important role in the possibility of successful establishment of invasive species. However, it is still unclear how personality traits of invasive species will respond to global warming. ...

Estrogenic hormones and organic ultraviolet-filters (UV-filters) have attracted increased attention as endocrine disrupting chemicals (EDCs) due to their potent estrogenicity widespread occurrence in the environment. This study investigated accumulation of three estrogenic five UV-filters red swamp crayfish (Procambarus clarkii). Exposure experiments were conducted for 42 days with a mixture ED...
