Crabs are scavengers that clean the reef floor of dead plant and animal material. We can help the reefs by never killing snails for their shells nor buying such shells in shops. Jacks, called ulua in Hawaiian, are often seen on coral reefs. For these strong swimmers, the reef is a hunting ground. In contrast are butterflyfish, commonly seen on coral reefs.
Some species spend their entire lives near a single clump of coral.
The sanctuary has come through with its promise of marine education. Now all we citizens have to do is take advantage of the offer. Marine science writer Susan Scott's Ocean Watch column appears Mondays in the Star-Bulletin.
