  The prospect of identifying wormholes by investigating the shadows of
wormholes constitute a foremost source of insight into the evolution of compact
objects and it is one of the essential problems in contemporary astrophysics.
The nature of the compact objects (wormholes) plays a crucial role on shadow
effect, which actually arises during the strong gravitational lensing. Current
Event Horizon Telescope observations have inspired scientists to study and to
construct the shadow images of the wormholes. In this work, we explore the
shadow cast by a certain class of rotating wormhole. To search this, we first
compose the null geodesics and study the effects of the parameters on the
photon orbit. We have exposed the form and size of the wormhole shadow and have
found that it is slanted as well as can be altered depending on the different
parameters present in the wormhole spacetime. We also constrain the size and
the spin of the wormhole using the results from M87* observation, by
investigating the average diameter of the wormhole as well as deviation from
circularity with respect to the wormhole throat size. In a future observation,
this type of study may help to indicate the presence of a wormhole in a
galactic region.
