Hexacorallia is a class of Anthozoa comprising of roughly 4,300 species of aquatic organisms formed of polyps, normally with 6-fold symmetry. This class includes all of the stony corals, most of which are reef-forming, as well as all sea anemones, and zoanthids, arranged within five orders. These organisms are formed of individual soft polyps which in some species live in colonies and can secrete a calcite skeleton. These organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant
extinct order of rugose corals.
This drawing by Ernst Haeckel embodies the love and intimate knowledge that he had about the things that he drew. His combines science and art in a way which onlya select few have been able to do in such a breathtaking way (like Leonardo da Vinci, for example).
