ABSTRACT
This chapter discusses the majestic manta rays are widely noted for the interest in divers, but similar curiosity is shown by the smallest to the largest of fish. In one, known as aggressive mimicry, they either blend into the background or, alternatively, stand-out conspicuously by imitating a non-threatening organism. Historically, fish have often been regarded as evolutionarily primitive with low intelligence and 3 second memories yet, countless observations of marine life have consistently shown that fish are notably intelligent and naturally curious. The relationship between form and function has been much debated since Aristotle and deeply considered by Darwin. The Oceanic sunfish, Mola mola, presents an interesting enigma. Although rarely seen on coral reefs, these gigantic fish make an unforgettably dramatic encounter at close quarters. The dual modes of mimicry mentioned above are particularly effective for the frogfish since, although they do change colour and texture to match their surroundings, the process can take weeks.
