San Pedro's Corals
A unique example of an artificial reef, San Pedro site is a fractured patch reef whose coral structure today reflects the past and present patterns of disturbance. San Pedro's corals grow mainly in clusters which are a legacy of extensi
ve salvage and treasure hunting activities that took place on the site since it was rediscovered in the early 1960's. Since the establishment of the preserve in 1989, IU had the opportunity to observe and document San Pedro corals. Below are some of the
latest images and video documentation of San Pedro's most significant corals.

The corals in this image compromise one of the largest coral clusters (C2) on the San Pedro site. The protruding corals on the left are two Symetrical Brain Corals (Diploria strigosa) spanning 2.4 feet that are join
ed by a patch of a Massive Starlet Coral (Siderastrea siderea). On the left are two, about 1 foot each in diameter, Massive Starlet Corals (Siderastrea siderea).

This 5 feet long coral cluster (C3) on the San Pedro is a conglomerate of Massive Starlet Corals (Siderastrea siderea) intersperesed with Orange Encrusting Sponge and reef building algae of Halimeda family.

For past 11 years this Massive Starlet Coral (C4) (Siderastrea siderea) has been home to a Basket Star. The top is encrusted by Fire Coral (Millepora alcicornis) and a variety of alga and sponges. |

Almost 3 feet in diameter, this boulder of a Massive Starlet coral (C5) (Siderastrea siderea) has tumbled off the balast stones. The area covered with Orange Encrusting Sponge is the "scar" on the boulder. The coral
is currently located exactly sixty feet southwest of the crown of the anchor. |

This video gives a close up view of Symmetrical Brain Coral
(Diploria Strigosa). Note that the coral grows on
a ballast stone in close vicinity of seagrass bed. |
