Subject: Close up and personal with a Day Octopus (Octopus cyanea). The octopus’ eye with its split-like pupils, work in a different way than the eye of a human. Man’s eye focuses by changing the thickness of the lens inside the eye where the octopus moves the lens in and forward, a bit like a lens in a camera. Octopuses have excellent eyesight, comparable to ours. Breathing happens through gills in cavities situated on both sides of their body. Expired water is channeled through a funnel.
Technique: To get so close isn’t that difficult, it just takes time. The time you need to build confidence so that when you get close, real close, the animal doesn’t flee. Show the animal that you’re not a threat, avoid sudden movements and increase the power of your lights gradually so you do not immediately bombard the animal with a blinding light beam.
