Subject: An Estuary or Common Seahorse (Hippocampus kuda) uses a seaweed leaf as his anchor. Seahorses use their elongated snouts to feed on small crustaceans and fish larvae. They are slow to digest their food as they have extremely simple digestive systems. The absence of a stomach means that they must eat continuously to stay alive.
Technique: When filming a subject close to or on the bottom it is best to pose your camera in such a way that it stays stable/unmovable and that you can film horizontally (avoid filming from above). Small camera movements are easy to correct in post-production with the stabilizer tool of your editing software.
