Physeter Follow-Up

After I posted this photo of a sperm whale from Ogasawara to Flickr, I received a comment/ question from Rick Pearson.

Here’s Rick’s comment:

Hey Tony, any more info about this particular whale? Is it a male (kinda hard to tell from this angle), and how big was it? I went to your blog page and didn’t find much more info there, just that it was very friendly. The reason I’m asking, is that the entire front, flattened portion of it’s head is gray, and there are lots of scars all over the head and around the mouth. I haven’t seen that much gray in any underwater sperm whale photo, and according to both scientists, and the old time Yankee whalers, that much gray on the front was most often found only on older, and therefore much larger, male sperm whales.

I certainly noticed the grey colouration right away when we came across this whale, largely because it made the whale easy to spot, but also, as Rick alludes to, most sperm whales don’t seem to have so much grey.

I wasn’t aware of any possible correlation with the whale’s age or sex, however.

Anyway, I promised Rick I’d find and post another photo of the same whale, showing the underside so we can at least decide if it’s a male or not, so here it is:

And here’s a zoomed-in view of the genital area:

The whale wasn’t very big, at least as far as sperm whales go. I’d estimate it was 12 metres long at most, and it didn’t have the bulk of a mature male. I’ve been in the water with two mature bull sperm whales, and believe me…when you see a big bull…you know it!

Anyway, the colouration is intriguing. If anyone else has any insights or relevant knowledge, please share!

Between The Lines

Photographing sperm whales can be a challenge for many reasons, including the fact that…well…they’re not always terribly photogenic. They often just look like big brown blubber logs with stubby fins, a tail and a mouth.


Making sperm whales look nice can be challenging.

Sometimes, you have to look between the lines…or in this instance, between the jaw lines…to see something interesting:


See the leftover squid arm? Note the big teeth too.

I have to confess that I didn’t notice the squid arm while I was in the water, since the whale passed by at relatively high speed. The swells were also considerable, which made framing the whale a challenge as well.

I can’t be 100% certain, but I suspect the leftover calamari segment was from an Architeuthis squid. From the above photo, it looks like the arm was attached to the whale’s face, perhaps as a result of the “teeth” on the squid’s suckers, which look like this (photo below from last year):

giant squid suckers

In October 2009, I recovered a 351cm segment of an Architeuthis arm from the water after we saw a sperm whale breach. I suspected at the time that the squid arm might have been attached to the whale and became dislodged when the cetacean breached.

This photo seems to offer some support for my conjecture.

Back From Ogasawara

I just got back from Ogasawara, where I was fortunate enough to spend some more time with sperm whales.

I’m not sure how much I’ll be able to write about the trip before I take off again in a few days, but here’s a sample image, taken during an encounter with a particularly inquisitive whale:

Talk: National Museum of Nature and Science

Last Friday evening, I did my first-ever talk in Japanese at the National Museum of Nature and Science, located in Ueno Park in Tokyo. My presentation was about sperm whales, and was the last in a series that accompanied a special exhibit about mammals, organised in conjunction with Asahi Shimbun and WWF Japan.

The talk was in the main exhibition hall, adjacent to a large life-size display of a sperm whale head with a giant squid in its mouth. My photo of a real sperm whale with giant squid in its mouth was located in front of the display.


Notice the sophisticated pointer I used.

A lot of people showed up (thank you!), perhaps the most for any of the talks held in conjunction with this exhibition (which says a lot about the high level of interest here in marine mammals).

Given that I had never made a public presentation in Japanese before, I was somewhat nervous, but I got into the groove fairly quickly and didn’t stumble too much (I think).

I did struggle for proper word choice a few times, but fortunately, Yamada-san from the museum’s Department of Zoology was on hand to help me through difficult topics like explaining the inner workings of a sperm whale’s enormous head.

After the talk, I answered a few questions, said hi to friends who were kind enough to drop by and listen to me ramble, and then went out for a couple of beers + great food with Yamada-san and a few other people from the museum.

All-in-all, a terrific evening.

I’d like to extend special thanks to Tamura-san from Asahi Shimbun for inviting me to do the talk, and also to the National Museum of Nature and Science for taking a chance on my Japanese language proficiency!

Talk: National Museum of Nature and Science in Tokyo

The National Museum of Nature and Science in Tokyo has been holding a special exhibition on marine mammals in conjunction with the Asahi Shimbun and WWF Japan.

The exhibition started on 10 July and winds up on 26 September. As of the middle of August, over 200,000 people have visited the exhibit!

My photograph of a female sperm whale consuming part of an Architeuthis giant squid is on display as part of the exhibit, and I am scheduled to give a talk on what it’s like to be in the water with sperm whales on Friday, 24 September, from 18:00 to 18:30.

Since the museum is in Tokyo, I’ll be doing my best to give the talk entirely in Japanese (gulp). Fortunately, Tadasu Yamada from the Division of Vertebrates in the Department of Zoology at the Museum will be on hand to help translate when I exceed the limits of my Japanese vocabulary.

I’m not exactly sure how the talk will go, but I’m planning to take along some sperm whale images and video clips from my recent trips to Ogasawara and Dominica.

If you can make it to the talk, I’ll tell you what it’s like to be in the water next to the largest living carnivore on the planet, to have your fin chewed by a sperm whale, to get ping-ed by sperm whale sonar, to watch a large group of socialising whales, and even to stroke an unusual sperm whale named Scar that seems to seek out human attention.

My talk is free, but there is an admission charge of 1,400 Yen to get into the museum. There’s a special rate of 2,000 Yen for two people together if you enter the museum after 17:00 on that day.

If you happen to be in Tokyo on 24 September, please drop by and say hello! Details are on this page (in Japanese).

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:

Thanks Wakae-san!

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):

…and second, a baby sperm whale (Physeter macrocephalus):

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.

andrew and scar

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.
