The Americana lock is a common grappling submission very similar to the Kimura lock. When the (bottom) opponent's hand is up by his head it is an Americana, when it's down by his waist it is a Kimura. This submission is commonly performed from side control (top position) and consists of grabbing your opponent's wrist with one hand and then weaving your other hand under their arm to connect to your own wrist. The attacker needs to keep their opponent's arm bent and then lift the elbow while using the double wrist control to rotate their opponent's hand under their arm, attacking the shoulder.
Other names: bent armlock, keylock, top wristlock, figure four armlock (catch wrestling), ude garami (judo)
The Anaconda is a blood choke where the opponent is strangled in between their own shoulder and your arm in something resembling a north-south position. The Anaconda is very similar to the D'Arce choke, they are both arm triangles from the front headlock position except locked up on opposite sides. From the front headlock if you thread the chinpick arm through to the armpit on other side it is an Anaconda, if you instead thread the elbow-grip arm from their armpit to their neck it is a D'Arce.
