  We show a new property of sonic black holes. After deriving the metric of a
sonic black hole from the Schrodinger equation and quantizing the perturbation
fields near the sonic event horizon, we show particles of Hawking radiation can
act as a source of entanglement: two-mode squeezed entanglement is produced
near the event horizon, which can be used in quantum teleportation. The
fidelity of the teleportation is closely related to the temperature of the
sonic black holes, but high fidelity seems difficult to reach in our case.
