So there I was, swatting mosquitoes on Victoria Island in the Canadian
Arctic. I didn’t come to this relatively remote island because I wanted to engage
in that vigorous activity, however. Rather, I came because I wanted to escape
what writer Norman Douglas referred to as “the perambulating lunatic asylum of
civilization.”

But I also came became I wanted to find an Arctic tadpole shrimp
(Lepidurus arcticus), a species that’s neither a tadpole or a shrimp but it’s own
particular breed. A scientist friend alerted me to the presence of this not
particularly common crustacean on Victoria Island.
Here I should mention that L. articus is the northern cousin of Triops, a
species that’s best known as an inhabitant of desert water holes in the American
Southwest. The main difference is that Triops species have three eyes (“Triops”
means “three eyes”), while L. articus have two. Another difference is that Triops
are relatively common not only in the Southwest, but on the internet — you can
purchase a larger number of their eggs on Amazon and watch them hatch in a
terrarium. Not so L. atticus, which can be found only in the wild.
Between swats, I peered into a shallow moraine pond with the hope of
finding the object of my scrutiny. I peered, and then peered some more, but all I
saw was a reflection of my own face in the water. Oh yes: I also saw quite a few
mosquito larvae swimming around at the bottom of the pond.
I wandered over to another moraine pond, gazed into it, and all of a
sudden I saw a horseshoe crab, albeit a miniature one —its humped carapace
was probably no more than an inch and a half long. The critter was a L. articus!

I was far more pleased by the sight of this relatively small arthropod than I would
have been if I had found a bag of gold!
I reached down and gently picked up the L. articus and ended up holding
in my hand a creature which happened to be one of the planet’s oldest living
species. Dare I say that this gave me a sense of primordial delight? The
creature in question did not seem to feel delight, though. Its twin poppyseed
eyes stared at me with what seemed like obvious displeasure. Clearly, this living
fossil did not like being held by a latter-day species, for it tried to spike my hand
with its telson, a pointed tail-like appendage on its abdomen.
I knew L. articis liked to eat mosquito larvae, so I tried to capture a few
from the bottom of the pond, but they kept swimming away. Then I wondered if it
might like to eat adult mosquitoes as well, so when one of these blood suckers
landed on my arm, I swatted it, and then put carcass the next to the L. articus in
my hand. Ah, success, I thought, when the L. articus began to wiggle toward the
mosquito…
…but then it continued wiggling until it escaped my grasp and splashed
into the pond, a much healthier habitat than the palm of my hand. Oh well, I
thought, at least I’ve had the pleasure of getting up close and person with an
early Jurassic survivor…

April 30, 1847. Ship lies groaning & straining in the ice off King William Island. On a whim, I brought out my maps of Arctic Canada, only to discover that the Admiralty had provided me with maps of Polynesia — an unfortunate error.
In the Middle Ages, Europeans had peculiar notions about Lapland. For instance, they thought all Samis (Lapps) were shamans. As it happens, many of them in fact were. Let’s say a sick person puts out a call for a noaidi (shaman). The noaidi would arrive at that person’s lodge in a reindeer-drawn sled. He would be obliged to enter via the chimney because the pile-up of snow prevents him from entering through the front door.
