New phenomena of ductile behavior are briefly presented that are mostly relevant for anisotropic materials. These include void rotation induced ductility enhancement under off-axes loading and two modes of coalescence that are different from the internal necking mode. The effects associated with some phenomena are of first order and the general question arises as to what microstructural parameters affect ductile behavior.
