Gandakasia is an extinctgenus ofambulocetid fromPakistan, that lived in theEocene epoch. It probably caught its prey near rivers or streams.

Just likeHimalayacetus,Gandakasia is only known from a single jaw fragment, making comparisons to other ambulocetids difficult.[3]

The first ambulocetid to be described,Gandakasia was not initially recognized as a cetacean.[4]

Gandakasia probably inhabited a freshwater niche similar to thepakicetids.[3]
