This enables it to find its prey even if it is burried in the sand. • The flying fish are attracted to light. This habit allows fishermen to catch them easily. • At night many Parrotfish secrete and then sleep inside a mucous cocoon. This cocoon protects it from parastes and snails, also helps it warn about the presence of predators and adds a horrible taste and smell to the parrot fish thus keeping the predators at a safe distance. • Some fish species are able to change their sex. Clown fish is a classic example of this, they are all born males and the dominant males change their sex during the course of life. • Bettas breathe air. If they don't breathe air they will drown. • Male betta fish builds a bubble nest for the arrival of eggs. • The Salmon fish spends most of its time in the ocean but comes back to the freshwater for spawning. • Oils from orange rough which is a deep-sea fish, are used in making shampoos.
