Species examined were: Ligia oceanica, Sphaeroma serratum, Idotea balthica, Talitrus saltator, Hyale nilssoni, Gammarid amphipoda and the mysid Pranus flexuosus. Feeding is known to decline near moulting; this may be because the chewing surfaces become loosened before moulting. Also the surfaces are worn down and useless, and feeding ceases. Very long intermoult periods, as found in old individuals, may thus cause long periods of starvation and this could enhance the symptoms of senescence.
