  One of the conspicuous features of real slices of bicritical rational maps is
the existence of Tricorn-type hyperbolic components. Such a hyperbolic
component is called invisible if the non-bifurcating sub-arcs on its boundary
do not intersect the closure of any other hyperbolic component. Numerical
evidence suggests an abundance of invisible Tricorn-type components in real
slices of bicritical rational maps. In this paper, we study two different
families of real bicritical maps and characterize invisible Tricorn-type
components in terms of suitable topological properties in the dynamical planes
of the representative maps. We use this criterion to prove the existence of
infinitely many invisible Tricorn-type components in the corresponding
parameter spaces. Although we write the proofs for two specific families, our
methods apply to generic families of real bicritical maps.
