some sharks do swim into coral areas but big sharks can get scratched by the coral
The environment for a coral reef needs to be well investigated. First of all, you need to mimic an outdoor coral reef using waves and sunlight. These are the essentials for an ideal coral reef. Also along with the reef, you should include fish. The fish will eat algi off of the reef and will make it more natural looking.
they block big waves
no one will protect our coastal communities from big waves
Kenya's coral reef stretches about 500km long(310 miles),and covers an approximate area of about 630 km.square.Its ranked number 54 in the world and constitute 0.22 percentage of the worlds total area.Kenya`s coral reef stretches from latitudes 1 degree,42` South to 4degree,40` South.
a coral reef is not one big animal, it is a bunch of small coral polyps growing on top of each other. the outer layer are the live polyps (coral is an animal) and they are on top of the dead coral skeletons. a coral polyp does not have a backbone because it is an invertebrate of cnidaria phylum. it has a skeleton made of calcium carbonate, or carbon and calcium. neither one coral polyp has a backbone and a coral reef does not have a backbone either.
They are not. I study elephants but have never found one on a coral reef. My associate studies big cats with similar results.
many different kinds. they help feed many different animals. and keep the water clean
Smaller
The area ratio is 32,27.
Very big. Western Australia is the largest state in Australia. Look up an image of a map of Australia and you'll see.
