Crescent-tail bigeye fish, Great Barrier Reef, Australia

Say hello to the crescent-tail bigeye, a fish as eye-catching as its name suggests. With large, wide eyes and a distinctive tail shaped like a crescent moon, it"s hard to miss. Measuring between 45 and 50 centimetres in length, it has a sleek body and a protruding lower jaw with small conical teeth. Its eyes are adapted to the low-light conditions of deep waters, helping it spot prey and avoid predators. This fish mainly feeds on smaller fish, crustaceans and invertebrates, fuelling its active lifestyle as it patrols reefs in search of food.
