National Museum Exhibit in Tokyo

I just received this snapshot of my photo of a sperm whale eating giant squid from a friend who visited the National Museum of Nature and Science in Tokyo earlier today. The photo is from a trip to Ogasawara, Japan in October 2009.

The special exhibit about marine mammals will continue until 26 September. I haven’t been able to see the exhibit yet, but I’ve received a lot of positive feedback.

If you’re in Tokyo and have time, it might be worth dropping by.

Incidentally, the same photo is also on display at the Natural History Museum in London, though friends tell me the sperm whale section is dark and difficult to find.

Thanks Michiyo-san!

Update 26 July: I received a couple more photos of the exhibit from another friend:

Bohol Bound

I’m heading out shortly to the island of Bohol in the Philippines.

It’s been a long time since I’ve visited the area…something like eighteen years or so…which means that for all practical purposes, I know nothing about the place.

This is an unscheduled excursion, in the sense that I didn’t plan it far in advance like I do for most of my trips. I’m heading over there to do a bit of work with Sony (which means I really have to pay attention to what I’m doing!).

I can’t really say much more than that at this point, but I can post a couple of photos that I took earlier this year in Dominica with a Sony DSC-TX5, which is a compact camera that’s ok to take into the water as-is (i.e., no housing required), rated to a depth of three metres.

Here’s a bunch of sperm whales gathered just under the surface:

And here’s a shot of a juvenile sperm whale swimming straight toward me:

The reason I’m posting these pictures is to illustrate how far digital technology has come. Sure…given a choice, I’m always going to opt for a high-end DSLR, but one thing I constantly tell people who write to me asking for advice about which camera to buy is that just about every camera made these days is capable of producing fantastic results.

These photos are proof.

Of course, there are differences between a $300 camera and a $3000 camera. There have to be.

But it’s more important to understand and work with the capabilities and limitations of the camera you have, than to fret over the functions of a camera you don’t have or can’t afford.

In the case of the Sony DSC-TX5…I knew that the camera is waterproof to three metres (that’s slightly less than 10 feet for the metrically challenged), so all I had to do was find cooperative sperm whales in clear, shallow water with good light. Easy!

Whale Watching at Home

Meet my new friend, a 50cm hand-carved wooden sperm whale, which arrived earlier today from Ogasawara.

The carving was specially made by an incredibly talented artist who lives in Ogasawara.

My friend and fellow photographer Douglas Seifert (who’s website has been “under construction” since the inception of the internet) has a carving similar to this one, and there’s a third on its way over to Eric Cheng.

I’ve named my new cetacean companion Scar, in honour of the friendly male sperm whale that I met in Dominica earlier this year.

Now I can go whale watching any time I want!

Big Babies

Just for fun…here are a couple of images of two very big babies, both having a good time at the water’s surface.

First, a baby humpback whale (Megaptera novaeangliae):

Andrew and Scar

Most of the media coverage coming out of our recent trip to Dominica has centered around our host Andrew Armour’s relationship with Scar, the friendly male sperm whale that seems to seek out and enjoy human interaction.

I’ve received a number of emails, comments and other communication about Andrew and Scar…primarily reflecting two things: curiosity and concern.

It’s entirely natural to be curious. It’s not often that one comes across examples of sperm whales playing with people (or people playing with sperm whales for that matter).

It’s also natural to be concerned, since sperm whales are the largest living toothed animal on the planet.

To augment the information in the media…

I have been in the water with sperm whales on three separate trips spanning six weeks or so in total duration. I’m certainly not as familiar with sperm whales as I am with humpback whales, but based on what I’ve seen, I think it’s reasonable for me to say that Scar is an unusual case.

Most sperm whales I’ve come across have been busy…feeding, procreating, travelling, socialising, resting…doing the things sperm whales normally do. As a consequence, most sperm whales are not in the habit of taking time to interact with people. There’s no benefit in it for them.

It is in this context that Scar is interesting. As I alluded to in an earlier post, Scar seems to play a lot…by himself, with the younger whales, and sometimes with people. He appears to play substantially more than the other adult/ sub-adult whales.

Watching Scar, I felt like he was sort of “in his own world”. It’s a difficult thing to pinpoint, but he didn’t seem to behave or interact in the same manner as the other whales in his group. He often seemed to be doing his own thing, such as rolling around in circles by himself while other whales rested together in a group.

This is pure speculation on my part, but if Scar were human, I would guess that he has a mild case of autism or something similar. It could, of course, just be his personality. I don’t think there’s any way to be certain.

In any case, adult male sperm whales usually leave family groups and head off to higher latitudes in the northern hemisphere (and lower latitudes in the case of the southern hemisphere) to lead mostly solitary lives until they’re ready for breeding.

Scar is overdue for a life of independence. At around ten years of age, Scar is mature enough to have left the area by now. Since he hasn’t done so yet, it’s reasonable to expect him to do so soon.

Of course, it’s possible that Scar somehow chooses to remain in the waters around Dominica, in which case…he’ll be really unusual. Time will tell.

Scar

Andrew Armour, who was our guide during the trip, has known Scar since the whale was a baby, having first come across him when the whale was injured at a very young age. Scar has apparently approached boats from the time he was a little leviathan and allowed people to pet him.

Sensible people would argue that it’s not wise to make physical contact with a large carnivore in the water. I would normally agree. I must admit a significant degree of concern and scepticism when I initially heard about Andrew and Scar.

But after seeing Scar for myself, and seeing how much he seems to enjoy human interaction, my scepticism and concern is significantly moderated. Scar approached all of us, and would not let us get away without stroking him. He closed his eyes and wriggled with delight upon contact (yes, I know that’s ascribing human characteristics to a whale, but picture a puppy squirming with enthusiasm and you’ll get the idea).

It was an amazing experience. Once again, I find myself struggling to convey an experience for which words are simply inadequate.

I would never recommend anyone rush off to try to pet any animal underwater. In fact, I would advise against anything of the sort.

But I also recognise that life is not black-and-white, and that exceptions to rules are often the most interesting things we come across.

Andrew’s relationship with Scar is real. Or perhaps more accurately, Scar’s penchant for human contact is real.

Bubbles

Still on the road…long journey back to Asia with a couple of stops along the way.

Still sleep-deprived, hence inarticulate.

Just felt like posting this photo of a sperm whale blowing bubbles. This happened toward the end of one of our encounters.

Story About Scar

We’re packed up and getting ready to leave Dominica. It’s been a fantastic first trip to this lovely island nation, and I’m looking forward to visiting again.

Before I head out, I thought I’d share a story about Scar, a male sperm whale that seems to seek out and enjoy human company. He’s the whale featured in the recent newspaper articles from our trip.

I was fortunate enough to watch Scar interact with his fellow cetaceans when there was no one else in the water (read…during a couple of exhausting, prolonged swims).

Scar seems to enjoy playing, whether humans are involved or not.

I watched Scar play alone…twirling in circles, doing loops, hanging upside down…while other whales in his group seemed to be busy doing other stuff. I also noticed that Scar seems to be the favourite uncle or older brother for the two calfs that were in his group.

Here’s a photo of the two calfs swimming along with Scar:

scar with two juvenile whales

I took this photo after witnessing an entertaining and memorable scene.

There are a few sperm whale researchers here at the moment, led by Hal Whitehead. During one of my prolonged swims with Scar, I saw the sonar array that they were towing behind their vessel, at a depth of around 20 to 25 metres.

Scar saw it too, and he swam down to take a look, eventually taking the the sonar array into his mouth for a taste test (I guess that’s the logical thing to do if you’re a sperm whale).

The two kids were swimming separately, but they must have noticed Scar having a good time, and they swam over, looked down at Scar, stopped to consider what Scar was doing, then rushed down to join in the fun.

Here are the two youngsters moments before they decide to crash uncle Scar’s party:

sperm whales with hydrophone

I laughed just enough to swallow a bit of seawater.

While we’re on the topic of sound, this is a short sample of sperm whale sonar communication, which we picked up on our boat’s hydrophone:

The most prominent clicks are from an adult male. There are other, more faint clicks in the background that are from females and/ or juveniles.

Off to the airport.

Head or Tails?

We had amazing encounters yesterday with a family of resident whales called the Group of Seven.

Among the group were a couple of relatively large calfs, both of which were inquisitive and friendly.

At times, it was almost as if they presented themselves for photos (of course, at other times, we had to swim like mad just to keep up).

In case you ever wondered what a sperm whale looks like head-on, here’s a photo:

head-on view of sperm whale

The lump at the top right (actually, the whale’s top left) is the blowhole, which is how the whale breathes. The pointy area at the bottom is the animal’s mouth. The attached remora and small school of attendant fish are optional accessories.

The splotchiness (is that a word?) is due sloughing off of dead skin. The darker patches are older skin, and the lighter patches are newer areas.

And to keep things in balance, here’s the view from the rear:

Attached remoras again optional.

All In The Family

Photographing open-ocean cetaceans can involve a lot of swimming.

For instance, to be accepted into this group of sperm whales required what seemed like hours of swimming as hard and fast as I could. In reality, it was probably only 10 minutes, give or take, but swimming for 10 minutes in ocean swell with the objective of catching up to and overtaking a group of whales is exhausting…especially if you keep doing it over and over again.

But on those occasions when whales slow down just enough to let me swim side-by-side with them for a while…it’s well worth the effort.

More Than A Mouthful

While we’re on the subject of big mouths from my previous post, here’s a shot of one whale mouthing another during a period of intense social interaction:

sperm whale mouthing another whale

This playful mouthing seems to be a normal and frequent behaviour, as we’ve seen it many times in the social groups.

It doesn’t seem to involve aggression, and there doesn’t appear to be any serious force involved…sort of reminiscent of the way puppies in a litter play-bite one another…but more gentle.

Say Ahhhhh

A couple of days ago, a large bull whale showed up to socialise with some of the younger males. Adult male sperm whales are huge.

In the water, it looked somewhere on the order of two to three times the size of the sub-adults, as well as being significantly greater in girth. They can grow to something on the order of 18 metres in length.

Of course, the pace of swimming was generally more rapid when the large adult was around, so it was difficult to keep up. After one extended swim, the whales took a right turn, giving me chance to close some distance…and this is what I saw:

The bull opened its mouth really wide, as if stretching its jaws. There was no aggression involved, and no sonar beyond the normal background chatter.

It was…to say the least…an impressive sight.

Baby Sperm Whale

We came across a baby sperm whale today, a fairly young one from the looks of it.

I’m tempted to say that the image below is a photograph of mother and calf, but it’s difficult to tell with sperm whales, as they practice communal care of young.

Note: The baby is swimming upside-down.

Female sperm whales help one another to look after babies, going so far as to practice communal nursing. I saw this baby nurse a few times with one of the adult females, but still…there’s no easy way to be completely certain of whether it was the baby’s mother or not.

In fact, I saw the baby “switch” adults a few times too, moving from one large whale to another as the group swam along.

The baby was part of an extended family group of whales that we stayed with for a couple of hours or so. I’m not sure how many whales were in the group, but the most I saw at any one time underwater was 13 adults plus the baby.

The following photo shows the baby with seven other whales.
