Propodus-dactylus joint in Sphaeroma serratum. a Scanning electron micrograph of the joint between the propodus and the dactylus in the aquatic sphaeromatid S. serratum. The dorsal side of the pereopod is at the top of the image. The propodal process does not form a full semicircle. Its thick edge fits into a smooth, semicircular groove on the dactylus. b Propodal process with the dactylus removed. Its curved ventral edge is thickened. c Higher magnification of the thick edge. Its surface is patterned and forms parallel ridges. d Ridges on the propodal process in S. serratum appear flat and cross-striated. Particles are trapped in the grooves between them. Scale bars: 50 μm (a), 20 μm (b), 5 μm (c), 1 μm (d)
