The photos were shot by a camera attached underneath Rockingham Wild Encounters� dolphin swim boat.
Director Aaron Heath said dolphins had an unusual way of eating the poisonous fish.
�The dolphins here just love to eat blow fish but as we all know their skin is quite poisonous,� he said.
�So they bite the tail and suck the flesh out and leave the skin behind.�
Mr Heath said the group�s swim crew also noticed the rapscallion dolphins tended to be more sexually active after eating blowfish.
�The swim crew seem to think that this a bit of an aphrodisiac, as the dolphins seem to be a bit �active� after having a blow fish feast,� he said.
�At times when blow fish spawn, the water can be filled with tiny baby blow fish and the dolphins love to eat these like popcorn.
�They don�t seem to have any issues with the poison in the baby blowfish, they eat them whole and it makes a popping.�
