deschauenseei, the darkly-spotted anaconda – a rare species, found in northeastern Brazil and coastal French Guiana Eunectes beniensis, the Bolivian anaconda – the most recently defined species, found in the Departments of Beni and Pando in Bolivia The term was previously applied imprecisely, indicating any large snake that constricts its prey, though this usage is now archaic. "Anaconda" is also used as a metaphor for an action aimed at constricting and suffocating an opponent – for example, the Anaconda Plan proposed at the beginning of the American Civil War, in which the Union Army was to effectively "suffocate" the Confederacy. Another example is the anaconda choke in the martial art Brazilian jiu-jitsu, which is performed by wrapping your arms under the opponent's neck and through the armpit, and grasping the biceps of the opposing arm, when caught in this move, you will lose consciousness if you do not tap out.
