Hamas claims it has captured one of Israel’s stealthiest secret agents — an undercover dolphin.

Divers working for the terror group say they seized a dolphin in the Mediterranean off the Gaza Strip that was equipped by Israeli intelligence with a remote-control camera, according to reports.

It was also found wearing another device from which harpoons large enough to kill a man could be fired remotely, Hamas alleged.

The Palestinian naval fighters wrangled the mammal to shore a few days ago after they spied it making “suspicious movements,” according to Arab news reports quoted by The Jerusalem Post.

The whereabouts and condition of the dolphin were not known, and Israeli officials have not commented on the animal.

Hamas believes Israel was using the dolphin either to keep tabs on the movements of its naval commandos — who are part of a group called Eziddin al-Qassam — or to target its operatives while they train at sea.

The group’s military officials claim the dolphin is proof that Israel has been waging an underwater espionage war off the Gaza Strip.

They say it also supports previous spying allegations against Israel involving members of the animal kingdom.

In recent years, birds tagged with tracking devices and other surveillance devices have been captured by Palestinians — including an eagle that was labeled a Mossad spy in 2012, according to The Times of Israel.

An Egyptian official has even gone as far as to say in the past that Israelis have been controlling sharks in calculated attacks on tourists swimming in the Red Sea.

It is not unusual for nations to draft aquatic mammals into service.

The United States reportedly has 85 dolphins and 50 sea lions that, since 1960, have been used for tasks such as spotting mines and locating enemy swimmers.

The $14 million US program, dubbed the Navy Marine Mammal Program, is based at Space and Naval Warfare Systems Command in San Diego, according to Business Insider.
