The sea jockey, or Mediterranean rainbow wrasse, is a bright sea fish up to 25 centimeters long. It lives near rocky shores and in seagrass thickets, changes color, and can change sex from female to male.
The sea jockey differs from other wrasses in its bright changing coloration and ability to change sex from female to male. It is important for nature because it eats small invertebrates and serves as food for large fish.
Immature form that undergoes metamorphosis before adulthood.
