The aim of the study was the development of habitat models for Nephtys species (Polychaeta: Nephtyidae). The investigation area was the German Bight, the southeastern part of the North Sea. Models were developed based on field data collected between

The impact of bioturbation on the geochemistry of aquatic sediments is known to depend on the benthic infauna species that are present. However, burrowing and activity patterns of each species may also change during the different stages of a life cycle.

The molecular size, shape and conformation of the extracellular hemoglobin of Nephtys incisa were examined using scanning transmission electron microscopy, small-angle X-ray scattering and circular dichroism measurements. In electron micrographs,
