The PINKTAIL TRIGGERFISH (called
humuhumu hi'u kole), also called the Pinktail Durgon, is dark brown with a
white tail, often with a pink tinge. The dorsal and anal fins are
cleanish-white and lined in black, and the pectoral fins are yellow. They
primarily feed on algae or plankton, but occasionally eat octopus, crustaceans
and other fish. Although typically skittish and quick to hide female
pinktails will become bold when guarding their eggs, with their dorsal spine
erect. Females protecting their eggs will even attempt to bite a diver
that gets too close.

Gray Reef Shark
The GRAY REEF SHARK (called
mano) is a gray shark on its back and sides, and lighter below. The dusky
margin on the tail helps to distinguish them from the Galapagos Shark.
They are territorial sharks and act aggressively toward intruders, although
they rarely bother divers. However, they show signs of upcoming attack if they
hump their back, raise their head and drop their pectoral fins. So fight
the urge to take photos of these sharks if you see those signs, especially if
your camera has a flash. Instead, slowly and calmly withdraw, never
taking your eyes off the shark.
Although these sharks are common in the
Indo-Pacific, they're not commonly seen in the Hawaiian Islands except around
Molokini, off Mauai, and around Niihau. Around Hawaii, most mating and
pupping occurs between March and July, and the gestation is 12 months.
Come dive with us and try to find one of these gray
reef sharks and admire from a safe distance!!

Smooth Seahorse
The SMOOTH
SEAHORSE lacks spines, most are black or brownish, but white ones are
occasionally seen, and females tend to be yellow. They're most common in
shallow protected environments, such as Kaneohe Bay. They're often
covered in algae and silt and are easily overlooked while diving. They're
a rare species, but they occasionally have population booms, most recently in
2005. They grow to be up to 8" in length with tail
outstretched.

Blue-Eye Damselfish
The BLUE-EYE
DAMSELFISH is a yellowish gray damsel with bright blue eyes and blue markings
on the dorsal and anal fins. They are found living among the branches of
living coral, feeding on coral polyps. They tend to spawn most frequently
between September and October, and again between February through May.
The male damsel creates a nest by killing a small section of coral. They
become very territorial against multiband butterflyfish, but do not become
territorial against other butterflyfish.

Multiband Butterflyfish
The MULTIBAND BUTTERFLYFISH
(called kikakapu) is a small butterflyfish that's light tan covered in brown
spots that form 4-5 vertical bars. They tend to swim in pairs and are
very common around the Hawaiian Islands, seen feeding on the coral.
Despite eating coral, they do minimal damage because they take a few nibbles on
a coral head and move onto another one. They've been noted to spawn
around dusk during the week before a full moon in February and March.
