response: I am not sure about that either. But I know something interesting: Beaches occur in areas where the sediments are deposited and reworked by current or wave action
original_response: yea well they typically occur in areas along the coast where wave or current action deposits and reworks sediments that can contain crawfish and crabs
history: I just love the beach do you know anything about it's coral reefs? Unfortunatelly I don't know anything about coral reefs, all I know is that beaches are composed by particles made from rock, like gravel, sand, pebbles and others Where do those materials come from?  Are they washed up from the ocean? I am not sure about where they are from but I know that they can have a biological origin also, like mollusc shells Do any animals live on the beach?
