Family
Poritidae
Lobe
& Finger Corals
|
Massive or branching species easily recognized by their
small hexagonal calices. Many are difficult to identify in the field since
ID's are based upon minute skeletal structures. Lobe and Finger coral are
dominant reef-forming species in Hawaii while the others are occasional in clear
waters.

FINGER CORAL
|
One of three dominant corals in
Hawaii. Prefers quiet shallow bays as well as deeper water with little
surge. The open water form is light gray and finger-like, creating
extensive thickets. The lagoon form in Kaneohe Bay is yellowish
green with short fused branches creating hemispherical mounds. Calices are
shallow and the outer wall is not sharp and elevated. Endemic to
Hawaii. Replaced by P. cylindrica in the Indo-Pacific.
