Trans- and Cis-Atlantic Distributions of Three Marine Heterotardigrades

Comparisons are made between specimens from areas on both sides of the Atlantic Ocean based on metric, meristic, and eidostic characters. In the Batillipedidae, the morphology of Batillipes tubernatis from Massachusetts, U.S.A. is compared with that of specimens from Britain, Germany, and Florida, U...

Description
Summary:Comparisons are made between specimens from areas on both sides of the Atlantic Ocean based on metric, meristic, and eidostic characters. In the Batillipedidae, the morphology of Batillipes tubernatis from Massachusetts, U.S.A. is compared with that of specimens from Britain, Germany, and Florida, U.S.A., and B. dicrocercus from Poland is compared with specimens from Massachusetts, Florida, and Italy; in the Halechiniscidae, Tanarctus heterodactylus from Delaware, U.S.A. is compared with specimens from North Carolina, U.S.A. and Brazil. All of the specimens considered here fall within the range of acceptable morphology for their respective species. Broad trans- and cis-oceanic distribution, therefore, seems to apply to these species and, by extension, perhaps to other meiofaunal species as well.
