Coral core

  • Exhibition Text

    • These are sections cut from a core of coral (Porites lobata) that grew between 1937 and 1994. This core shows well-developed alternating light and dark layers. Each pair of the layers indicates one year’s growth. The horizontal lines are the skeletons formed by each individual coral polyp as it grew. Also visible are small, scalloped markings that show where fish grazed on the coral.
