Aspects of the biology of iron, copper and other metals in relation to feeding in<i>Andaniexis abyssi</i>, with notes on<i>Andaniopsis nordlandica</i>and<i>Stegocephalus inflatus</i>(Amphipoda: Stegocephalidae), from Norwegian waters

TL;DRAbstract

Abstract Data are presented on the gut contents, ventral caeca fine structure and concentration of metals (Fe, Cu, Zn, and Cd) in Andaniexis abyssi and Stegocephalus inflatus captured live off Bergen. Additionally, some observations on gut contents and ventral caecal fine structure are also given relating to preserved Andaniopsis nordlandica collected off. the Norwegian coast. Andaniexis abyssi stomachs from shelf and fjord locations contained sand grains, muscle(?) tissue, fragments of arthropods and other animal remains together with dark granules. Animals derived from the fjord location also contained nematocysts. Andaniopsis nordlandica stomachs likewise contained sand grains, much larger quantities of nematocysts, arthropod fragments and muscle tissue, together with occasional brown crystals. The dark granules in Andaniexis abyssi stomachs are interpreted as voided Curich granules, the brown crystals in Andaniopsis nordlandica as voided ferritin crystals. The mouthparts of Andanie
