OK, another one. There is apparently a "pygmy" subspecies of the blue whale, which "only" reaches 24 meters in length. LOL. So apparently some kind of early warning system á la Dr Strangelove detected two previously unknown populations of said pygmies in the Indian Ocean, one around the ill-reputed Chagos Archipelago, the other in the vicinity of Oman.
I admit this little story made me somewhat more optimistic about the prospects of cryptozoology...
