Octocorals,
Soft Corals, Gorgonians, & Sea Pens
| Octocorals have a variety of forms ranging from delicate mats to sea
fans & massive leather corals. They share a common trait in
having polyps with eight tentacles (hard corals have six).
Octocorals are most prolific in areas of high water flow where they
capture zooplankton with stinging cells. Identification of many
species is difficult beyond the genus or family level without
dissection. Hawaii has a relatively few species at diving depths
compared to other parts of the world. |
