We analyze the entanglement spectrum of superfluid phases of
3He, the 3D B-phase and the planar phase in two dimensions.
We find explicitly the wave functions of the low-lying eigenstates,
including Majorana zero modes, as well as the corresponding part of the
spectrum of the entanglement Hamiltonian.
