Groupers are carnivorous fishes that are typically large and slow moving, found under ledges and caverns.  They feed primarily upon fishes and large crustaceans.  Due to the high fish diet, many shallow water reef species can contain enough ciguatoxin to cause illness and caution should be exercised when eating fish in areas where ciguatera poisoning is common, including Hawaii..

True Groupers or Sea Basses are nearly absent in Hawai'i.  The only fish divers are likely to see is the blue-spotted Peacock Grouper that was intentionally introduced in 1956 (that was dumb) along with the dreaded Ta'ape.  Several other large groupers were released but fortunately none became established.

There are three native species recorded from Hawaiian waters.  Several Jewfish weighing hundreds of pounds have been caught, but none have been reported recently, therefore the population may have been wiped out.   The Hawaiian Grouper Hapu'upu'u is a deepwater endemic caught while bottom fishing.  It may be seen by divers at Midway along with the colorful Schlegel's Grouper.
