Distribution
Leptodiaptomus ashlandi is a zooplankton species widely distributed across Canada and the northern half of the United States in large deep lakes. It occurs in all the Great Lakes.[1]
Identification
Lua error in package.lua at line 80: module 'strict' not found.Adult females of L. ashlandi can be distinguished by their two-segmented urosome and asymmetrical, rounded metasomal wings. Males are characterized by a large lateral spine on leg 5, located in the proximal third of the terminal segment, and by the presence of a slender process on the third segment from the distal end of the right antennule.[2]This species is morphologically similar to other Leptodiaptomids (Leptodiaptomus minutus, L. sicilis,) and Skistodiaptomids (Skistodiaptomus oregonensis).
