  We show the existence of an infinite collection of hyperbolic knots where
each of which has in its exterior meridional essential planar surfaces of
arbitrarily large number of boundary components, or, equivalently, that each of
these knots has essential tangle decompositions of arbitrarily large number of
strings. Moreover, each of these knots has in its exterior meridional essential
surfaces of any positive genus and (even) number of boundary components. That
is, the compact surfaces that have a meridional essential embedding into a
hyperbolic knot exterior have meridional essential embeddings into each of
these hyperbolic knots exteriors.
