The distribution of the ribbon leech, NepMlopsis obscwra, was examined in the Central Lowland and Missouri Coteau regions of North Dakota. The leech was found in 12 of3S ponds sampled during a two-year period. Leeches were trapped with throated metal cans and burlap sacks baited with frozen fish parts. Leech ocamence was positively correlated with maximum depth, mean conductivity, and percent l...

Placobdella cryptobranchii (Johnson & Klemm, 1977) was originally described from specimens collected from Ozark Hellbenders (Cryptobranchus alleganiensis bishopi) from the North Fork of the White River in Missouri, U.S.A. Leeches collected during August 2009 to August 2011 from five localities in Missouri (including the type locality) facilitated a redescription and molecular characterization o...

The oscillations that underlie swimming movements in the leech arise from a series of identified concatenated circuits within the ventral nerve cord. In the intact nerve cord, ascending and descending intersegmental interactions via axons within the lateral connectives function both to generate robust oscillations throughout the cord and to establish an anterior-to-posterior phase delay among s...
