The Rhinomuraena quaesita, or ribbon eel, is known for its vibrant coloration and elongated body. Found in Indo-Pacific reefs, it exhibits a fascinating color change from male blue to female yellow. The ribbon eel's unique, tube-like nostrils and mesmerizing swimming patterns make it a standout species in marine ecosystems.

Rhinomuraena quaesita, commonly known as the Ribbon Eel, is native to the Indo-Pacific region. This species is typically found in the warm waters of the Indian Ocean and the western and central Pacific Ocean. Geographically, it is distributed from East Africa to southern Japan and northern Australia, including the Red Sea, Indonesia, the Philippines, and the Great Barrier Reef.

Ribbon Eels inhabit coral reefs and lagoons, preferring areas with abundant coral cover and sandy or rubble substrates where they can easily burrow. They are usually found at depths ranging from 3 to 60 meters (10 to 200 feet). The water temperature in these regions is generally warm, typically between 24°C to 28°C (75°F to 82°F), which is ideal for coral growth and, consequently, for the Ribbon Eel's habitat.

Ribbon Eels are carnivorous, primarily feeding on small fish and crustaceans. They are known for their unique and vibrant coloration and spend most of their time hiding in crevices within the reefs, with only their heads protruding to ambush prey. They play a critical role in the reef ecosystem as both predator and prey, contributing to the ecological balance by controlling the population of smaller fish and invertebrates.
