Which substrate type is utilized by wrasses that burrow for protection or sleep?
Answer
Sandy or rubble areas adjacent to reefs
While coral reefs are primary habitats, wrasses utilize adjacent transitional zones based on their specific needs. Certain species have adapted to make their homes in areas dominated by sandy bottoms or rubble situated next to the main reef structure. This substrate is essential for species specialized in burrowing, allowing them to dive into the sand for protection against nighttime predators or simply to rest when they are not actively swimming or feeding.
