Dragonets - Callionymidae
DRAGONETS - CALLIONYMIDAE
These small bottom-dwellers are easy to recognize because they have both protrusive mouth and eyes and both protrude out of their head. Their eyes are able to move separately in different directions and this helps them to look out for predators and food. Most of the species blend well into their surrounding even though some are very colorful. The males are bigger and have a larger first dorsal fin which they use to show-off during courtship, or when having rivals. The most famous of all is of course the very colorful mandarinfish or Synchiropus splendidus. All dragonets mate and spawn just after sunset.
