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? 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 I just love to eat crabs for dinner.  I wonder what attracts them to the area. I can't confirm you the reason but I know that they are the largest arthropod that lives in land in the World. Imprevise, right? I wonder how big these animals could have gotten in ancient times.
knowledge: It is found on Indonesia, islands across the Indian Ocean and parts of the Pacific Ocean as far east as the Gambier Islands mirroring the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar.
