Reportedly a cetacean commando working for the Israeli Defense Forces was caught by Hamas operatives as it was making suspicious movements off the coast of Gaza. When Hamas combat divers (I had no idea they had such a thing) examined the dolphin spy, they said it was strapped with a camera, a monitoring device and an spear shooting contraption capable of killing a human. That is one deadly-ass dolphin.
Hamas thinks the dolphin was there to track their frogmens training as part of an ongoing intelligence operation to support Israels naval blockade of Gaza.
While a spy dolphin sounds completely insane, this is not the first time Israel has been accused of pitting the animal kingdom against its enemies. According to Sputniknews.com there has been a long history of accusations, some totally absurd, that Israel has animal warriors on their side:
In 2013, Egyptian police were reported to have temporarily detained a duck, after a local fisherman saw a device with Hebrew writing attached the bird, believing that it could be used to gather intelligence. In 2012, Turkish media repeatedly alleged that birds tagged with tracking devices by Israeli universities were being used for espionage missions.
Also in 2012, a vulture with an Israeli tag was captured in Sudan, and touted to be a Mossad spy. Israeli officials had to explain that only the vulture itself was being tracked, as part of a study on the migration patterns of the rare species. In 2011, some Saudi Arabian media accused Israel of using a griffon vulture for espionage purposes. In 2010, an official in Egypts Sinai province said that rumors of Mossad dumping a shark in the Red Sea near tourist areas deserved serious investigation.
Although there are no known reports of trained sea mammals working for the IDF, the use of dolphins and sealions for military purposes is not unheard of. The U.S. has maintained a marine mammal program dating back to the 1960s and today the animals are used to defend critical infrastructure from swimmer attacks, to locate sunken equipment and to identify mines and underwater explosive devices.
