Bucket List Biggie – Whale Watching


Humpback Whale
The main reason we went to Ólafsvík was to go Whale watching with Láki Tours. I was excited because I had seen so many reports of recent trips with Humpbacks, Orcas, Blue Whales and Sperm Whales. I had seen the first three on other trips: Humpbacks and Orcas many times, and Blue Whales once in California with Caty.

I was really looking forward to seeing a Sperm Whale, which Láki had been seeing on trips throughout the month. I have never seen one; Scott has.

I was also prepared for a cold, windy, wet, rough trip because, well, Iceland. 

I suited up with my G Adventures parka and lots of warm gear. Imagine our surprise when the day dawned sunny, calm and warm. I didn’t know what kind of gear to take.

When the Láki people opened up (we were the first whale watch of the day), they insisted we all wear their one-piece jumpsuits so that we would be protected from inevitable splashes. So, off went the G Adventures parka and on went the suit. With my cameras, I also took all my waterproof gear.

Getting ready to find some Whales
It turns out it was all unnecessary. The weather stayed warm and calm. We had no splash and the only wind was when we were traveling quickly. Most of the time I was comfortable and some of the time I was warm. Scott spent the whole trip with the top of the jumpsuit off and hanging around his waist.

Oh, and before we even got on the boat, I had a wildlife sighting: pretty little Moon Jellies in the harbor ...

It was a gorgeous, glorious day. Now, we just needed Whales.

And, we got them. A number of Humpbacks (I can’t remember how many, maybe eight). While they didn’t do anything spectacular – no breaching, no tail slapping, no spy-hopping – they did swim rather close to the boat on several occasions.

There was a great deal of fluking (diving with the tale up for leverage) ...

Humpbacks are showy: they fluke up quite a bit
... and lots of round-up diving (bending the back without fluking – the inspiration behind the name “Humpback”) ...

The traditional "humped" Humpback
The coolest thing that happened was, fortunately, after I had gone up to the top deck to get a different perspective on some Humpbacks. One swam up to and under our boat. I could see its entire outline through the clear blue-green water. It was amazing to see and I captured it fairly well with my camera.

You can clearly see the entire Humpback Whale
I am not going to write much about Humpbacks, because I just recently covered them in my blog about Maui. I am also not going to write about Orcas because we didn’t see any. 

Orcas, Alaska
That was a bit of a surprise because Orcas are kind of Láki’s thing. Their winter Orca sightings were why Caty and I went to Iceland in 2015 (but we didn’t see any) and the reason several of our fellow watchers on this trip had booked. I wasn’t too disappointed because I have seen them before, including some incredible sightings last year in Alaska (do I have a great life or what?). 

I am sure some people were disappointed, but the other sightings made up for it.

What were they? Well, the captain and a crew member saw one Minke Whale, but we didn’t. So, I am not counting that.

As we were heading out into and back from Breiðarfjörður, we saw a pod (or two pods) of White-beaked Dolphins. These are feisty critters, swimming and cavorting around the boat as we skimmed through the water. They even had babies with them.

Of course, there were birds: a nice, sun-shiny close view of Atlantic Puffins as they swam …

… and then struggled to take off, as Puffins do ...

He finally got off the water, but it took forever
There were graceful Arctic Terns, flying and fishing (look closely at its beak; it’s taking lunch home) …

And, I got another – and a better – look at some Razorbills …

What a cool-looking bird
But coolest of all was Blue Whales. Yes, Blue Whales, five or six of them over the course of the trip. The first one was pretty far away and I was concerned that it was going to be one of those trips where you saw a lot, but it was all distant (this was before we saw the very-up-close Humpbacks). 

Blue Whale!!
But, then, one surprised us (and, apparently the captain) by surfacing right by the boat.

It got better after that. There were Blue Whales everywhere. What a treat. I had previously seen four off the coast of California near Channel Islands National Park. These five-six we saw were Scott’s first. Just six years ago, I thought I would never see one. Now, I was up to nine or ten!

So, let’s talk about Blue Whales …

Blue Whales
Blue Whale are generally difficult to see because they don’t usually come too far out of the water. In fact, even though I had seen Blue Whales before, this was the first time I had ever seen the fluke – and it was a brief glimpse. 

The elusive Blue Whale fluke
They are long (very – about 100 ft.) and sleek with a very small dorsal fin and long, thin pectoral flippers, and a distinctive U-shaped mouth. 

A tiny dorsal fin
Their mottled blue-grey back is distinctive for each whale and it is their skin pattern that is used for identification (as opposed to Humpback Whales, which are identified by their unique fluke patterns).

Each skin pattern is distinctive
The largest animal to EVER live on Earth, the Blue Whale is about twice as long as a T-Rex dinosaur and weighs 100-150 tons. Calves are about 25 ft. long and weigh the same as an adult African elephant. Females are generally a few feet longer than males, but males have slightly heavier muscles and bones.

The Blue Whale’s  average life span is 85 years, although 110 years has been confirmed for at least one Blue Whale.

Reproducing once every two or three years, female Blue Whales carry their young for 12 months before giving birth. Calves stay close to their mother's side for around six months, initially drinking up to 100 gallons of fat-rich milk every day. How rich? The milk contains 35 to 50 percent milk fat and allows the calf to gain weight at a rate of up to 10 pounds an hour or more than 250 pounds a day!

Ardent travelers, Blue Whales annually migrate to cold waters to feed and then to warmer waters to breed and look after their young. They eat very little while traveling and survive mostly on their blubber reserves for up to four months at a time.

Blue Whales are rorqual Whales, a family of baleen Whales with pleated throat grooves that expand when they take in water while feeding (other members of the family are Humpback, Fin, Bryde's, Sei and Minke Whales). Baleen, hard plates of keratin edged with long fringe-like hair, occurs in ridges on the roof of the Whale’s mouth. 

Blue Whales can have 300-800 baleen plates. Ironically, the largest animal on the planet survives by eating one of the smallest. Blue Whales eat mainly krill, a tiny shrimp-like creature found in huge swarms in the ocean. A single Blue Whale can eat as many as 40 million krill a day – that’s two-four tons. Because krill move, Blue Whales typically feed at depths of more than 300 ft. during the day and only surface-feed at night. Dive times are typically 10 minutes when feeding, although dives of up to 21 minutes are possible. The Whale feeds by lunging forward at groups of krill, taking the animals and a large quantity of water into its mouth. 

It is rare to see anything other than the Blue Whale's back
The water is then squeezed out through the baleen plates by pressure from the ventral pouch and tongue. Once the mouth is clear of water, the remaining krill, unable to pass through the plates, are swallowed. The Blue Whale also incidentally consumes small fish, crustaceans and squid caught up with krill.

You can see the twin blowholes
Blue Whales have twin blowholes shielded by a large splashguard. When surfacing to breathe, the Blue Whale raises its "shoulder" and blowhole farther out of the water than other large Whales. Its blow is a vertical single-column spout, typically 30 ft. high, but reaching up to 39 ft.

Preferring to live in deep ocean waters, Blue Whales are rarely seen close to shore. In the Southern Hemisphere, small populations remain in the Antarctic, as well as parts of the Indian Ocean. In the Northern Hemisphere, they can be seen in the northeast Pacific from Alaska to Costa Rica as well the North Atlantic near Newfoundland, Nova Scotia, Greenland and Iceland.

Blue Whales can reach speeds of 30 mph over short bursts, usually when interacting with other whales, but 12 mph is a more typical traveling speed. When feeding, they slow down to 3 mph, which is equivalent to a medium-brisk walk.

Blue Whales typically swim at a depth of about 45 ft. when migrating in order to eliminate drag from surface waves. But, they can dive; the deepest confirmed dive is 1,660 ft.

Getting ready to dive
At one time, there may have been as many as 350,000 Blue Whales. Almost rendered extinct by whaling and industrial hazards, there are now only 10,000 to 25,000 left.

The Blue Whale was too fast and powerful for the 19th century whalers to hunt, but with the arrival of harpoon cannons, they became a much-sought-after species for their large amounts of blubber. Soon, Blue Whales were being hunted off Iceland (1883), the Faroe Islands (1894), Newfoundland (1898) and Svalbard (1903). In 1904-05 the first Blue Whales were taken off South Georgia. By 1925, with the advent of the stern slipway in factory ships and the use of steam-driven whale catchers, the catch of Blue Whales, and baleen whales as a whole, began to increase dramatically. The killing reached a peak in 1931 when 29,649 Blue Whales were taken. By 1966, they were so scarce that the International Whaling Commission declared them protected throughout the world. Today, they are still considered an endangered species.

The earliest known modern Blue Whale is a partial skull fossil found in southern Italy, dating to between 1.25 and 1.49 million years ago. That Whale is estimated to have been between 75 and 85 ft. long, overturning a previous hypothesis that baleen whales rapidly reached their modern sizes at 300,000 years ago. Now, it is believed that they changed more gradually around 3.6 million years ago, possibly earlier.

Due to their enormous size, power and speed, adult Blue Whales have virtually no natural predators.

A close-by Blue Whale
There are several documented cases of Orcas attempting to take a Blue Whale: one off Baja California where the Orcas didn’t kill the Whale outright, but it died later of injuries; one off California where an Orca pod harassed a Blue Whale and bit off the tip of its fluke, causing the Whale to tail slap the Orca; and one in Monterey Bay where the Orcas swam in a line up to the Blue Whale's side. 

Blue Whales may be wounded, sometimes fatally, after colliding with ocean vessels, as well as becoming trapped or entangled in fishing gear.

Climate change may create problems for Blue Whales because they migrate based on ocean temperature. The change in ocean temperature could also affect the Blue Whale's food supply if decreased salinity levels caused by glacial melt changes krill location and abundance.

So, after a virtual festival of Humpback and Blue Whales, it was time to go back. As we accelerated, we heard a loud slap behind us. We turned around to see a White-beaked Dolphin breaching. And it jumped and jumped and jumped. It was an amazing sight.

Acrobatic White-beaked Dolphin
Now, I had seen White-beaked Dolphins before: once by our ship on my first visit to Norway in 2014 and once in fjord outside of Tromsø on this trip. Both times I got photos that required a forensic scientist to interpret. Not this time. I got a lot of good pictures and so did Scott, who saw some much closer than I did (we were at different places on the boat).

White-beaked Dolphins
White-beaked Dolphins are toothed whales, similar to Orcas
The White-beaked Dolphin is technically a “toothed whale,” like other Dolphins, Orcas and Sperm Whales.

Adults can reach 7½ to 10 ft. long and weigh 400 to 780 lbs. Calves are 3½ to 4 ft. long at birth and weigh about 88 lbs. The upper body and flanks are dark grey with light grey patches, including a “saddle” behind the dorsal fin, while the underside is light grey to almost white. The flippers, fluke and the dorsal fin are all a darker grey than the body. As the common name implies, the beak is usually white, but it may be a dark, ashy grey, in some older individuals.

Mama and baby acrobatics
White-Beaked Dolphins have 25 to 28 teeth in each jaw, although the three teeth closest to the front of the mouth are often not visible, failing to erupt from the gums. They have up to 92 vertebrae, more than any other species of oceanic dolphin. 

Although the young are born with two to four whiskers on each side of the upper lip, these disappear as they grow, and the adults are entirely hairless. 

Swimming in tandem
The humerus bone of the right flipper is longer and more robust than the one on the left, indicating that, like people, White-beaked Dolphins tend to be right-handed.

The White-beaked Dolphin is endemic to the cold temperate and subarctic waters of the North Atlantic Ocean, most commonly in seas less than 3,000 ft. deep. 

They are found in a band stretching across the ocean from Cape Cod, the mouth of the St. Lawrence River and southern Greenland in the west, around Iceland in the center and across in the west from northern France to Svalbard (but we didn't see any in Svalbard). 

They are most commonly found on the Labrador Shelf close to southwestern Greenland, around Iceland, off the northern and eastern coasts of Britain and off the coast of Norway. 

White-beaked Dolphins have distinctive coloring
They are not well adapted to truly arctic conditions, which makes them more vulnerable to predators, most notably Polar Bears.

A small pod
A big leap
Population, breeding patterns and life expectancy are unknown, although several hundred thousand White-beaked Dolphins are estimated. They are more densely populated in the eastern North Atlantic than the west.

White-beaked Dolphins feed predominantly on fish, particularly cod, haddock and whiting. Social animals, they are most commonly found in groups of less than 10, but sometimes in much larger associations of more than 100.

Described as “acrobatic,” they frequently ride the bow wave of high-speed boats and jump clear of the sea's surface. 

That is for sure! 

Although they are normally much slower, they can swim at up to 20 mph and can dive 150 ft. deep. 

Bow wave riding
They are social feeders and often feed with Orcas and Fin and Humpback Whales, as well as with other Dolphin species.

A Great Trip
So, it was an extraordinary Whale watch, with beautiful skies, blue water, Humpback Whales, White-beaked Dolphins, seabirds and Blue Whales. No Orcas or Sperm Whales, which, of course, were seen later that week on other whale watches. Sometimes it might be better NOT to see reports of other trips! 

Humpback fluke
Now, I wish I had planned another day or two and gone out a couple of more times. But, Scott had other stuff he wanted to do. And, that’s in the next (and final of this series) blog.


Trip date: June 15-July 4, 2019
