Amphipod silk is a fibrous, self-secreted, adhesive substance employed in tube-building by amphipod species within the Corophiidea, Ampeliscoidea and Aetiopedidea. In the present study we provide a detailed characterisation of a novel, marine-based s

The funnel of Gammarus oceanicus extends as a fold of the foregut wall into the midgut lumen. It comprises an anterior segment, to which both foregut epithelium and cuticle contribute, and a posterior segment that lacks the epithelium. The latter seg

Polygonal patterns on the surface of epimeral plates of adult Gammarus oceanicus were compared in matched areas of exuvial and postmolt cuticle samples. The patterns, which record dimensions and locations of epidermal cells at premolt, were used to a

Morphometrically mature male snow crabs, Chionoecetes opilio, are not known to molt; they are believed to lack functional Y-organs and hence molting hormones. Small regions of the dorsal surface of crabs were damaged and the ensuing repair of the cut

Transmission electron microscopy was used to analyze the structure and organization of the intracuticular pore canal system in 34 species of amphipod crustaceans. Pore canals were detectable in all species, including those that, from scanning electro

The cuticular surface of the head and second coxal plate of 124 species (104 genera) of Amphipoda has been examined by scanning electron microscopy. Most of the species examined possess a variety of microstructures that are presumed to be nonsensory,
