Are you afraid of failure,
or of success? underwater photographer Amos Nachoum had asked me.
Face-to-face with an Orca underwater, I concluded that I was scared of
successvery scared.
I was in the Lofoten Islands of northern Norway on a two-week diving
trip led by Amos to search for Orcas, and I wasor so I thoughtdesperate
for an underwater encounter with these toothed whales.
But
when the Orca came zooming through the night-black waters to inspect me,
all I could think about was its mouth and its teeth. Orcas arent
called killer whales for nothing, or so my addled brain told me.
A more rational mind might have remembered that although Orcas are called
killers, they are eaters of sea-dwellers, not of humans. Often
working in organized packs, these wolves of the sea pluck basking seals
off beaches, stalk migrating whales twice their size, play catch with
Manta Rays and, in at least one recorded instance, attack Great White
Sharks.
They dont try to taste things that they dont know,
Amos had said, and they have so little familiarity with humans that they
consider us a novelty, not dinner.
There
is no record of an Orca in the wild wounding a person and only one case
of a captive Orca causing a fatality. Besides, there are better things
to eat than humans. According to Orca-researcher Anna Bisther, whom I
met in the Lofoten, herring are such a delicacy for the Orcas that they
wont be interested in humans. (However, the fact that she has only
once been diving with the whalesshe prefers to gather scientific
data by listening to hydrophones and making surface observationsdid
leave doubts in my mind.)
In the fall, herring (fat from a summer spent near Iceland) migrate north
to the long, narrow fjords of the Lofoten in search of deep water and
the deep sleep of hibernation. But for many herring, its a permanent
sleeplast year almost 600 Orca followed in their wake, single-mindedly
tracking one of their favorite foods. The combination of this large number
of Orca and good underwater visibility usually makes these rock-strewn
islands an excellent place to dive with Orcas.
The final factor keeping humans off the menu is that Orcas in the Lofoten
tend to live in pods, matriarchal social groups of five or more whales.
Podding Orcas prefer fish, according to scientists. And the transient,
nomadic Orcasperhaps outcastsgo for mammals like seals and
whales.
So if I was so safe, why was I scared?
Though
balmy by arctic standards because of the Gulf Stream, the 40°F waters
of the Lofoten would suck the life out of most of us in minutes; so we
wore dry suits. Now, multiply this with wind-tossed wave crests that look
like Lofoten mountain peaks. The result, at least for my version of this
formula, was that my insecurity in the environment was complete.
Not that I noticed. Instead of contemplating my oceanic inexperience,
I would launch off the boat like my life depended on it, finning fast
and furious toward any Orcas I could see from the surface.
They can tell when youre hypertense, Amos warned, somewhat
pointlessly since it wasnt like I could help it.
As a result, my encounters were transient, like the ray of sunlight that
once during the trip crawled down through the omnipresent clouds, a reminder
that somewhere the sun existed. Underneath me, Orcas would rush past,
swimming sideways to get a better look at the strange, flippered creature
silhouetted at the surface. Or, prompted by my diving down, theyd
double-back, belly up, for a fly-by. The worst part wasnt that the
encounters were brief, but that I was so anxious I couldnt appreciate
them.
Bubbles
are an Orcas bread and butter. Using bursts of precisely placed
bubbles, Orcas herd deep-swimming herring close to the surface. The Orcas
then slap their tails into the ball of herring. (On a hydrophone, the
tail-slap sounds just like a door slamming.) With one slap of its tail,
an Orca can kill 40 or more herring. But instead of wolfing them down
several at a time, the Orca will feed on them one-by-one, delicately,
like picking flowers.
Of the 40 or so Orca pods that frequent the Lofoten, only about nine hunt
this way. Amos calls the technique carouseling and believes
that the pods have learned to do it. In 94, one of the first
years of Orca diving, only one or two pods were carouseling when we were
swimming. Now many more do. The other pods seem to herd the herring
against the shore and then slap their tails into them, but this procedure
is less productive.
When
herring numbers dropped in the early 70s, the Orcas were blamed.
And then they were hunted. In the early 80s, fishermen and others
killed 400 Orcas in the Lofoten. Scientists and the Norwegian government
stepped in to restrict hunting and enforce fishing quotas, and, by the
end of the decade, both Orcas and herring were returning to the area.
Now both species seem to have reached their pre-70s populations.
But the Orcas are still getting back up to speed on how best to capture
their favorite food.
I saw some of the carouseling behavior. I saw an Orca swimming the circumference
of a ball of shimmering fish, sidling into it like a cat rubbing up against
a post.
As we rocketed over the waves, Orcas sometimes swam along with us. They
generally kept their distance. But as the largest members of the dolphin
family, the Orcas couldnt always contain their curiosity. Several
times they approached the boat and rose up out of the water to get a better
look. They were rewarded by our oohs and ahs and,
when it wasnt pouring, by the clicks of our cameras.
We also watched them slap their tails against the surface of the water,
along with head-butting and jaw-snapping (behavior that may be an expression
of dominance). Orcas have an elaborate system of movements and pod-specific
vocalizationswhistles, chirps, trills and other sounds produced
by air movements in the region of their blowholethat establish the
pods social structure.
Mothers never stray from their calves. The mother-calf bond is so strong
that if the calf dies, she will mourn it by cradling it in her front fins,
or try to resuscitate it by pushing it to the surface to make it breathe.
Among adults, even sleeping is a social experience. Two Orcas will trade
off sleeping, Anna said, with the wakeful Orca pulling the dormant Orca
by its dorsal fin. They will then switch positions.
On one of our last successful diving days, I had the face-to-face encounter.
My first reactionfear of being eatenwas replaced by overwhelming
awe as the Orca swam away.
Being
so close to an Orca underwater is perhaps akin to a religious awakeninga
blessing from a consciousness apart from ones own, a blessing that
made me feel that all is right with the world. Everything seemed to gel.
Perhaps I was no longer scared of success; perhaps I learned, finally,
to enjoy the moment and appreciate the world.
And while I was still in this state, seven Orcas approached, a wall of
black-and-white bodies closing down on me. Like the other encounters,
our meeting was fairly brief. But, for once, I wasnt afraid as they
zoomed up at me. I didnt think of their teeth. I thought only of
their beauty.
I am now ready for my next Orca encounter. Bring it on.
