I will report on morphological estimators of the filamentary structure of the Cosmic Web, the so-called skeleton. Based on a global study of the matter density gradient flow, it allows us to study the connectivity between a density peak and its surroundings, with direct relevance to the anisotropic accretion via cold flows on galactic halos. It also provides a theoretical framework to study their cosmic evolution through the onset of gravity-induced non-linearities. http://uk.arxiv.org/abs/0911.3779
