The event horizons of stationary black holes are marginally outer trapped surface (MOTS). For dynamical spacetimes numerical relativists continue to track these surfaces as proxies for black hole boundaries. In this talk I will review recent (and ongoing) analytical and numerical work on MOTS. We will see that inside the apparent horizon (the outermost MOTS of a black hole) there is a rich interior structure including infinite families of self-intersecting MOTS. During a black hole merger these interior structures play a critical role in the construction of the MOTS equivalent to the event horizon “pair of pants” diagram.
