1. What are mesophotic coral reefs?Mesophotic coral reefs are colorful coral gardens that live in the ocean's twilight zone, between 30 and 150 meters deep, where the light is much dimmer than at the surface.
2. Why are mesophotic reefs called the "twilight zone"?They are called the twilight zone because they are deeper than shallow reefs and receive far less light, similar to the dim light of twilight.

Mesophotic Coral Ecosystem (MCE): A marine ecosystem found at depths of 30-150 meters, characterized by dim light penetration and unique coral communities.
Endemic Species: Species native and restricted to a particular geographic region, not found naturally anywhere else.
Ecological Refugia: Areas that provide a safe haven for species during periods of environmental stress or habitat degradation.
Heterotrophy: The mode of nutrition in which an organism derives its nutritional requirements from complex organic substances.
