The copulatory apparatus of Obama has a protrusible penis occupying the entire male atrium or most of it.

The name Obama is formed by a composition of the Tupi words oba (leaf) and ma (animal), being a reference to the body shape of species in this genus.[3] Unlike Baracktrema obamai, Tosanoides obama, and Etheostoma obama it is not named after Barack Obama and the similarity between the names is pure coincidence.

Thanks Obama…
