I dont remember if there were others along the way, but the cadre of top secret spies trained to collect information by sea, land and air has grown with the newest recruit.

According to the JPost, Hamas is claiming that a Zionist dolphin was used by Israeli forces to chase Hamas frogmen off the coast of Gaza. This Zionist dolphin was not just collecting information, and don't think "chasing them" was a figment of their imagination - this Israeli employed and trained dolphin was brandishing a weapon and was seeking to kill these frogmen.

I did a tiny bit of research and discovered that dolphins do actually eat frogs (should they ever cross paths), as they are carnivorous, so this accusation and claim is actually completely reasonable. The dolphin was trying to kill the frogmen so it could have lunch, and then would also bring back the secrets to its Israeli Mossad handlers. I assume the information was just going to be an added bonus.
