One of the most beautiful ocean fish found on coral reefs, the queen angelfish. It gets its name from the "crown" on its head. Their bright colours are a scare tactic to predators, warning them to "Stay away!".
Usually, scuba divers can easily approach without scaring away these fishes as long as you refrain from any sudden motion.
Parrotfishes are important in maintaining the diversity and health of coral reefs. They are herbivores. Think of parrotfishes as the weed whackers of the coral reefs. They use their beak-like mouths to graze on algae preparing new surfaces for colonizing creatures.
On the downside, they can be very destructive. Ever wondered where all the sand-like ground coral comes from? Yup, grinding away at coral they can affect the clarity of the water around reefs at times during the day. These fishes leave evidence of chomp marks on coral affecting coral health,
* Here's an interesting fact :-
They are hermaphroditic (can change from female to male)! Isn't that cool?!
