The uptake of macromolecules and larger energy-rich particles into the cell is known as
phagocytosis. Phagocytosed material is enzymatically degraded in membrane-bound …

The structure of the gut barrier and luminal chemistry in non-mammalian vertebrates and
invertebrates has been given little attention with respect to the dietary uptake of engineered …

The ingestion of microplastics has been shown for a great variety of marine organisms.
However, benthic marine mesoherbivores such as the common periwinkle Littorina littorea …

The phylum Mollusca is one of the largest and more diversified among metazoan phyla,
comprising many thousand species living in ocean, freshwater and terrestrial ecosystems …

We investigated the histology and histochemistry (of carbohydrates and proteins) of the
digestive tract of the freshwater stingray Himantura signifier. The alimentary tract consists of …

Although Aplysia depilans is a widely known European species and the type species of the
genus, the distinctions that separate it from other related congeners are not entirely clear …

To continue the investigation on the digestive system of polyplacophoran molluscs, a
histological and ultrastructural study of the oesophagus, stomach and intestine of …

In addition to water and small inorganic ions, macromolecules traverse the uterine
epithelium in viviparous skinks to be absorbed by the developing fetus. In some species of …

The esophagus and intestine form the longest regions of the digestive tract in the giant
keyhole limpet and are lined by epithelial cells sharing a common morphology and …

Invertebrates harbouring endosymbiotic chemoautotrophic bacteria are widely distributed in
a variety of reducing marine habitats, including deep-sea hydrothermal vents …
