Obama (genus)
''Obama'' is a genus of land planarians from South America.
== Description ==
The genus ''Obama'' is characterized by having a leaf-shaped body. Most species are about 10 cm long, but some may reach over 20 cm. The hundreds of eyes distributed along the body are of two types: monolobulated, which are simple and circular, and trilobulated, which have three lobes. The copulatory apparatus has a permanent conical penis occupying the entire male cavity. It is very similar to the related genus ''Cratera'', the main difference being the absence of trilobulated eyes in the latter.
