The coral reef looks very different at night as once the diurnal animals, the reef will look bare and still. After a while, nocturnal creatures soon emerge from their hiding and the reef is soon back to life as nocturnal creatures are active at night.
Coral polyps, worms(not the ones that you find in your garden), sea stars, eels, lobsters and octopuses are all nocturnal thus creatures that eat them come out at night at night. Talk about supper!
Some animals such as the squid are bioluminescent which means that they create a glow inside their body. Some scientists think that they do that to attract prey by simply to flash their lights on and off. Yummy!
