Aspect: Oblong body of varying mottled colours (predominantly white and light brown) with white dots on the back. Head is preceded by tentacle-like arms with rows of suckers on their undersides, while a pair of wing-like triangular fins run from either side of the body, from the back of the head to the rear of the pointed body. Population: Common, especially at night, tend to have their "corners". Notable feature: Has the ability to dramatically change change colour patterns, sometimes several times in a second, which makes it look very "electric". Environment: Reef. Behaviour: Not too wary, especially if initially approached head-on.
