of Marine Life, Census of Coral Reefs Expedition to
French Frigate Shoals (October 2006)
Target Habitats: All proposed habitats including Forereef,
Reef Crest, Backreef, Intertidal Shores, Lagoonal Sands,
Lagoonal Patch Reef, La Perouse, Arc shell reefs, Acropora
Target Organisms: Sessile and mobile epifauna; macrosponge
This is the most general method employed by invertebrate
zoologists for the collection of macrofauna. Animals are
taken by hand, placed in bags or jars with ample seawater,
and taken to the shipboard lab for study. Many species
are simply taken from the reef surface; others are taken
from under rubble. For the latter, loose pieces of coral
rubble are gently lifted, targeted specimens secured, and
the rubble replaced in the same position as it was found
to cause minimal disturbance to other organisms. One example
demonstrating the efficiency of this method is that of
sponge and opisthobranch fauna hand collected in Guam.

component of the reef biota lives exclusively on sponges,
numerous organisms occurring on and inside marine
sponges have been described as "an ecological community,
in which, however, interrelationships are not yet clear" (Westiga
and Hoetjes 1981). Neither is their systematics or their
host specificity well understood. In order to observe and
collect them, subsamples of tissue are removed from the
macrosponges that have been collected for identification.
The pieces of sponge are collected in mesh bags, maintained
in running seawater in the laboratory, and dissected to
remove associated animals.
