Daytime in the reef is as busy and as colourful our daily lives on earth. For us, its car, buses, busy people walking up and down, mothers trying to hush their babies...its the same in the sea, just that instead of all that, we have very busy fishes.
Thousands of fish hunt or graze on sea plants, like corals. Some eacape from enemies or some really hungry prey who hasn't eaten for days...while others defend their area against intruders. Close to two-thirds of reef fish are diurnal otherwise known as active during the day. Turtles and snakes also visit the reef in the daytime.
At the end of the day, the brightly coloured fishes change to slightly duller shades so that it's harder for crespular fish to spot. Crespular fish are fishes that are active in the day and in the night. Talk about 24/7! Some examples of crespular fish are: sharks, barracuda and groupers. As the tired daytime creatures go home for a good nights sleep, they make good and easy target for alert predators. Have a happy feast, dear sharks, barracudas and groupers!
