The bottle-nosed Atlantic dolphins - Makai and Tacoma - have been taught by the US Navy to help divers hunt down Iraqi mines in the waters.
The navy is training more than 70 dolphins and 20 sea lions to do the job.
Their mission is very important because the mines planted by Iraqi troops must be moved to allow ships carrying vital aid through to Iraq.
Clever sonar
The mammals find mines using their natural sonar.
But the clever dolphins are trained to stay away from them when they see one.
Once they spot a mine, they are taught to drop a floating marker which tells divers where the explosives are.
This means they stay out of danger too.
According to the US navy, they are keen and work very hard.
Anger
But animals rights campaigners are angry the animals are being used like this.
They feel they are being exploited, are just being taught tricks and could get hurt.
Although the US navy say the only real danger they face comes from other dolphins who might not like new faces in their waters.
