Description
Kuei-Chiu Chen and Ramaswamy Narayanaswamy report a small freshwater crustacean, the tadpole shrimp Triops cancriformis, in Qatar for the first time. The species is well known in Europe and North Africa but rarely recorded in the Middle East, and almost nothing was known about its genes there. At a single site, the pair checked body features and read two genes to place the animals on the family tree.
Body traits matched one subspecies while the genes matched another, adding to earlier hints that the two forms may not be truly separate. The Qatari animals were all female and genetically uniform, and their closest relatives live in Germany. The authors infer a recent arrival, most likely as sleeping eggs carried in by migrating birds.
