Subject: The Porcupinefish (Diodon hystrix) is a durophagous carnivore (a carnivore that consumes hard-shelled or exoskeleton bearing organisms, such as urchins, clams, crabs, etc.…). They are well known for their ability to inflate themselves by swallowing water when threatened, causing their spines to extend outwards and avoiding most predators from consuming them.
Technique: Always try to obtain a frontal shot of the animal. Filming fleeing fish or the back/rear/tail of any creature won’t make great footage. Your subject is more likely to cooperate and might show its best side to the camera when you stay calm and don’t chase or scare it.
