Vestigial organs are the structures which have no visible function in a specific living being possibly once they did.
They seem, by all accounts, to be a leftover part of an earlier progenitor.
Some vestigial organs in the human body are - Wisdom Teeth, Palmaris Longus Muscle, Male Nipples.
Names of those animals in whom same organs are functional are - Appendix, External Ear, The Coccyx or tail bones.
They are usually just the extra in the human body and if they are removed that there are no much problem for the human.

Answer:
Vestigial organs is a term used for organs which are degenerated, underdeveloped or useless for an organism. Usually, with the changes in the outer environment, the organs undergo a gradual change in order to cope up with those changes. Presence of vestigial organs is an indication that they were useful for our ancestors but as we evolved with the changing surroundings, these structures lost their functionality but our still found in our bodies. It is not compulsory that if an organ is vestigial for humans, so will it be for other organisms too.
