Anon been looking at these PDF's

https://www.secnav.navy.mil/foia/readingroom/CaseFiles/UAP%20INFO/RF%20Reports%20Navy%20Redacted%20(202306).pdf

Lots of redactions, hard to read but here is the screen shot of the one that mentions a pod of whales. It's on page 51

i might add that some are ballons and some can move around by themselves
