What two types of rays typically compose the dorsal and anal fins of wrasses?
Answer
Spiny rays mixed with soft rays
The morphology of the fins plays a crucial role in the stability and movement of wrasses within their environment. Specifically, the dorsal fin, which runs along the back, and the anal fin, located on the underside near the tail, are structured to incorporate both spiny rays and soft rays. The presence of the spiny rays provides essential structural support and rigidity, aiding the fish in maintaining stability, particularly when it needs to hold its position steady against strong ocean currents or during precise hovering movements near reef structures.
