Outside the Nigali Pass
by Howard Hall
We
slipped off the Undersea Hunter's skiff two miles south of
the Nigali Pass and began the long swim along the outside
edge of the reef. At sixty feet, our underwater IMAX(R)® dive
team spread out six-abreast and slowly moved north looking
for banded sea snakes foraging in the coral below. Sea snakes
were the subject of a short sequence I hoped to film for our
IMAX® film, Coral Reef Adventure, scheduled for release in
March 2002.

I
was anxious to find a couple more sea snakes so that we could
finish our film sequence, and the hours that passed without
spotting a snake could be frustrating. But dives like this
are why I continue to make underwater wildlife films. "It's
the process that counts," I keep telling myself. "Enjoy the
process." I enjoyed watching the reef drift by beneath me.
A
dark shadow interrupted the cobalt-blue water seaward of the
reef. I recognized the shadow as a pinnacle I thought of as
"the thumb." Peter Kragh and Betty Almogy dropped down to
one hundred and twenty feet skirting the outer edge of the
pinnacle. From high above they seemed suspended in space.
Betty was looking for a pair of clown triggerfish she had
seen nesting the previous day. She thought, quite rightly,
that I should shoot a sequence of these colorful fish as they
engaged in reproductive behavior. I had put off the idea wanting
to get the sea snake sequence finished first. The question
of when to do the clown triggerfish sequence became academic
when Betty ascended and signaled that the fish were gone.
I had waited too long.
Filming
a sequence when the opportunity presents itself, instead of
waiting until tomorrow, is a lesson I keep relearning the
hard way. Of course, it's difficult to break stride, drop
a plan you're working on, and suddenly switch to filming another
sequence right in the middle of a dive. But some of the best
wildlife behavior I've captured has been filmed just that
way. In this case, I figured that if the clown triggers were
nesting, they'd be at it for days. I figured wrong, again.
Anyway,
there would probably be room for only one triggerfish nesting
sequence in the film and I planned for that sequence to star
titan triggerfish. These very large and colorful animals were
nesting all over the reef. Swimming along, we would pass over
a nest every minute or so. Common as dirt. Titan triggerfish
were also very aggressive in defending their nests. Cat Holloway
had a small scar on her ankle where a titan had bitten her
a year earlier. And I'd seen a picture in a fish identification
book of a woman who had been struck in the forehead by one
of these fish leaving a nasty cut. Looking at that photo,
I'd found it a bit hard to imagine how you could be dumb enough
to let a fish bite you in the face.
I
planned to work on the titan triggerfish sequence as soon
as we finished with sea snakes. I only needed a couple more
shots of the reptiles before moving on. "I've got one over
here," a voice said through my underwater earphone. I recognized
Cat's voice immediately. Cat Holloway and Rob Barrel of Nai'a
Cruises have been acting as our local guides and marine life
experts while we worked in Fiji. There is no substitute for
good local knowledge when making a wildlife film. Despite
having six divers searching the reef for sea snakes, nearly
all the snakes we'd found were discovered by Cat. It seemed
like coincidence, but I knew better. She was familiar with
the animals and was simply better at spotting them. Filming
the sequence would have taken at least twice as long without
her help.
"We're
on our way," I responded to Cat. "Surface copy?"
"Surface, go ahead," John Anderson responded
from the skiff drifting a few hundred yards away.
"Launch the camera. Launch the lights. Launch
Michele and Rusi," I said into my rebreather mouthpiece.
"Launching camera. Launching lights. Launching
Michele and Rusi," John confirmed over the comm.
"Ok, ok, ok," I said.
I
couldn't see Cat from where I was, but she always out-swam
the rest of us, so I knew she must be further down the reef.
After a few minutes of swimming I saw her hovering thirty
feet above the coral looking down at the reef. When she saw
me approach, she pointed down at a banded sea snake moving
slowly over the corals. I glanced to my left and right and
saw most of the other divers converging on our position.
A
lot of things would happen now as the team went into action.
Betty or Peter would surface marking the position. The camera
boat driver would bring the camera into position for launching.
The separate lighting boat would move in bringing the surface
powered cable lights into position. Mark Conlin would enter
the water to receive the IMAX® camera as John Anderson winched
the 250-pound system over the side. Mark Thurlow would accept
the movie lights from the other boat and Betty Almogy would
help drag the cables into position. Bob Cranston would ascend
to get a second underwater IMAX® camera to film the team and
me as we shot the sequence. Michele and Rusi would descend
from the lighting boat. Cat kept her eyes glued on the snake
as the logistics for filming underwater in IMAX® fell into
place. Me? I didn't do anything. I just waited and watched
it all happen as I'd done hundreds of times before. And it
was fun to watch. The team worked like a well-oiled machine.
Peter
and Mark mounted the lights on the camera and passed it over
to me. I adjusted the focus and exposure then flipped the
power switches for the camera and the video viewfinder. When
I was ready, I looked up to see Michele and Rusi on their
way down. "Michele, when I say action, pick up the snake gently.
Hold him for about twenty seconds then let him go. If he begins
to act unhappy, let him go sooner. Rusi, you hang about ten
feet behind Michele," I said. Both Michele and Rusi gave me
an OK signs. They understood. I glanced around to make sure
all the other divers were out of the frame. I noticed Bob
above and behind me with the second camera. He nodded that
he was ready. I said, "Action!"
The
scene went perfectly. I wanted to show that these highly venomous
but docile creatures did not deserve a reputation as being
killers. Michele gently holding the snake would help drive
that point home. During previous dives, I'd filmed Michele
getting close and looking at but not touching the snake, conforming
to the more modern diver ethic of "look but don't touch."
The editors at MacGillivray Freeman Films could cut the sequence
either way.
The camera ran for about thirty seconds and then Michele released
the snake and it resumed foraging on the reef, obviously undisturbed.
We shot the sequence a few more times before running out of
film. Then I sent the camera up for a fresh film load. That
would take about fifteen minutes. While we waited, however,
the snake swam into a hole and went to sleep. If I wanted
to shoot more sea snake footage, we would need to find another
snake. I called John on the boat and told him to hold the
camera after it was loaded. Then I instructed the dive team
to resume moving down the reef.
As
I swam, I reviewed the sequence in my mind and figured that
we had enough footage to make it work. I decided that if we
didn't find another snake before reaching the Nigali Pass,
we should move on to the titan triggerfish sequence tomorrow.
That should be an easy sequence. They were nesting everywhere.
We
had already been underwater nearly three hours. Fifteen minutes
later the reef began curving east and I realized we were entering
the pass. I looked over my shoulder to see if I could spot
Bob, Mark, Cat, Betty and Peter, but I could only see Bob
and Mark as fuzzy shapes in the distance. When I turned back
to look forward all I could see was the huge, ugly face of
a titan triggerfish about four feet away as it rushed at my
face with incredible speed. I had no time to move, raise my
hands, or even anticipate what was coming. SMACK!

I
took the impact on my forehead just above my left eye. It
was like being hit by a thrown rock the size of your fist!
I saw stars! I put my hand to my forehead then stupidly looked
at my fingers expecting to see blood on them. My hand came
away from my face in a green cloud. Yep, I was bleeding.
I
suddenly realized that I was swimming up and backwards, instinctively
trying to get away from the insane fish. Then I saw it still
swimming fast as it circled its nest in a state of high agitation.
The nest was over thirty feet away! The crazy fish had attacked
me more than thirty feet from its nest! I pressed the button
on my comm. microphone and called to Mark and Bob. "Hey guys,
see where I am? Avoid this spot. There's a mad triggerfish
here that just bit the hell out of me!"
Back
on the Undersea Hunter, I looked in the mirror to discover
a cut about an inch long over my left eye. It wasn't quite
worth a band aid. But the apricot-size lump beneath the cut
testified to the impact. I immediately realized that the cut
was in exactly the same position and was the same size as
the cut on the forehead of the dumb woman I saw in the photograph
a few days earlier. Well, she's probably no dumber than me,
I thought.
The
following day we went back outside the Nigali Pass to begin
work on our titan triggerfish sequence. They were gone! All
of them! Where there had been hundreds of nesting triggerfish
the day before and on every dive we had made near Fiji's Gau
Island, now there were zero! I couldn't believe it. I suddenly
realized that triggerfish nesting must be simultaneous. Simultaneous
spawning is known in corals and many broadcast spawning fish.
But I had never heard of nesting fish coordinating their reproductive
behavior. During our previous dives I'd wondered why I never
saw courtship or egg laying behavior as I swam over countless
nests. Now I knew the answer. If the egg hatching was simultaneous,
then mating and egg laying had to be simultaneous. Thousands
of triggerfish, all along the reef, had simultaneously built
nests, mated, and laid their eggs. A few weeks later, the
eggs all hatch at the same time. I then realized that I must
have passed that crazy triggerfish's nest just as the eggs
were hatching. That's why the parent was insanely protective
With
nesting over in Fiji, there was no way that nesting triggerfish
would now appear in MacGillivray Freeman's film, Coral
Reef Adventure. But I won't forget what I learned. Perhaps
when I return to Fiji aboard Nai'a for my next film project
I'll get the sequence on high definition video. Perhaps I'll
bring a football helmet. |
