Corals look like colorful underwater rocks and plants, but in reality they are a combination of exoskeletons from invertebrate polyps. These polyps will continue to multip and create an identical copy of themselves to replace themselves. Over time, coral exoskeleton structures become larger and larger.

Corals can live for hundreds of years or more, and blackhorn corals are among the longest-lived corals. The name comes from its black or dark brown bones, but its tissues are brightly colored. The Cape Nichrove coral reportedly found off the coast of Hawaii is 4,265 years old, making it the oldest coral species on Earth. #人人能科普, there are new knowledge ##Wonder Animals##自然上头条 everywhere #
