Though the name suggests it, baby octopus are not actually the young of adult octopuses. Baby octopus are actually adults of a species called octopus aegina. The octopus aegina are nicknamed baby octopus because they are small compared to other octopus. These baby octopuses are usually smaller than the palm of your hand. Before cooking fresh baby octopus, they should be cleaned. Cleaning can be done by beginners, as it is simple and quick.
Use a knife to carefully cut out both of the eyes.
Find the mouth/beak of the octopus. It is located between the arms. Push it out and remove completely.
Use a knife to cut a slit in the head. The head is the big round area. Turn the head inside out. Gently but firmly remove the entire contents. Take care not to break the ink sac.
Rinse under clean running water.
