Eyewitness accounts and finding new animals

This is not a new topic for me (or anyone who dabbles in cryptozoology) but it came to my attention when a thread began in the FaceBook group Cryptozoology, where one writer suggested that, not only are eyewitness reports insufficient to prove an animal exists, but that, by themselves, they are meaningless.

I think that's taking it one step too far  Eyewitness descriptions are, and have always been, one of the three major ways zoologists are led to new animals. There are really ONLY three ways (countless variations, but three main categories of events) in which a new animal CAN be discovered by science. They are 1) discovery of body parts (bones, trophies, things made from the animal's skin, etc); 2) scientific surveys where scientists are in the field looking for every animal in a targeted area; and 3) eyewitness accounts (either fresh or traditional) that alert scientists or explorers to the possibility of an animal and inspire expeditions to find it. Most of Dr. Alan Rabinowitz's mammal discoveries, for example, came from asking local hunters about their animals. Sometimes they could show him a trophy: other times, they described an animal they had seen and told him, or guided him, to where it could be found. As I said, there are many variations on these categories, but the idea that eyewitness encounters have not been crucial to important animal discoveries is certainly not valid.

(By the way, if you are curious what Dr. Rabinowitz has been up to, he's in the fight of his life: battling cancer while trying to save the tigers of Myanmar.  I'm in awe of the man.)

Such sightings serve as a starting point for investigators: they are not "proof" of a creature, but they can prompt us to ask interesting questions which we can then approach with the modern tools of science. The sightings of the chevron-marked beaked whale called  Mesoplodon Species A are a good example, leading eventually to an identification (which frankly still seems a little weak to me, but I have to yield to experts like Robert Pitman and company here) of this animal as the adult form of the pygmy beaked whale. Cryptozoology, properly understood, is the application of zoology, scientifically and objectively, to the discovery of new animals: the distinction is that cryptozoology opens the aperture a bit to open files on cases which are not quite as well attested as those leading to, say, the finding of the Vu Quang ox and company

What is the eyewitness report is not followed by anything more substantial? At what point do we toss it out?

Let's say it's 1908 or so, and you open a sea serpent file based on the report made by two naturalists on the yacht Valhalla. Interesting sighting, just published in the Royal Society's Proceedings - perfectly logical thing for a scientist to do. Then you wait. Do you close the file if twenty years pass without the animal being found? Probably not - the sea is a big place. Fifty years? Maybe - 50 years without a sighting was the old IUCN standard for extinction. 100 years? Well, depressingly, it's entirely logical to close the file. (I haven't quite, but I recognize I'm on shaky ground). In other words, how long does it take for absence of evidence to become evidence of absence? Maybe there should be a 50-year standard, but the cahow or Bermuda petrel was rediscovered 300 years after extinction. Some of it depends on whether the habitat can be searched: small lakes have been thoroughly searched (and dynamited) and the hypothesis (in Karl Popper’s sense of the falsifiable hypothesis being the basis of science) that there were creatures in those lakes have been properly falsified. It would take enormous and unavailable resources to falsify the hypothesis "There is an unclassified North American ape," but you can do it in theory. For the hypothesis, "There is an unclassified elongate marine species sometimes called a sea serpent" you could still falsify it in theory by active searching, but the task is too vast to even consider. Can the lack of followup evidence be considered falsification, and after what period of time? You inevitably end up in the world of opinion.

It’s not true that “my opinion is as good as yours” (see the Pitman example above).  But it’s also true that every researcher needs to use their own judgment – hopefully skeptically (in the proper sense of that word) – when evaluating witness reports. Witnesses can be right, they can be wrong, or somewhere in the middle. But I do hold they very often give science the starting point in discovery of a new animal.   

Tennyson: Ringing out 2013

Wherever you are, whatever you believe, this is the greatest poem ever written about looking to the New Year with hope.

In Memoriam, [Ring out, wild bells]

by Lord Alfred Tennyson

Ring out, wild bells, to the wild sky,
   The flying cloud, the frosty light:
   The year is dying in the night;
Ring out, wild bells, and let him die.

Ring out the old, ring in the new,
   Ring, happy bells, across the snow:
   The year is going, let him go;
Ring out the false, ring in the true.

Ring out the grief that saps the mind
   For those that here we see no more;
   Ring out the feud of rich and poor,
Ring in redress to all mankind.

Ring out a slowly dying cause,
   And ancient forms of party strife;
   Ring in the nobler modes of life,
With sweeter manners, purer laws.

Ring out the want, the care, the sin,
   The faithless coldness of the times;
   Ring out, ring out my mournful rhymes
But ring the fuller minstrel in.

Ring out false pride in place and blood,
   The civic slander and the spite;
   Ring in the love of truth and right,
Ring in the common love of good.

Ring out old shapes of foul disease;
   Ring out the narrowing lust of gold;
   Ring out the thousand wars of old,
Ring in the thousand years of peace.

Ring in the valiant man and free,
   The larger heart, the kindlier hand;
   Ring out the darkness of the land,
Ring in the Christ that is to be.

Reviewing a top scientific thriller: Invasive Species

Invasive Species
Joseph Wallace
Berkley, 2013


Joseph Wallace has done everything right in this thriller: good characters, a killer premise, well-researched locations, and gruesomely scary details.  But what really separates this from the pack is that Wallace, unlike many authors, has the science down cold.  His "thieves" are several evolutionary steps beyond any known insect, but you can work out why they would have evolved this way, and the result is terrifyingly plausible.  The hive-mind intelligence gets a little far out when the hive mind is connecting individuals separated by entire continents, but even here Joseph isn't just hand-waving it: he grounds the thieves' capabilities in what we know about hive minds and mentions the genuine scientific questions we still have about how they might work.  His concepts of how parasitic hosts exploit and control their prey have real analogues in nature, including those hellishly alien fungi that control the minds of ants.
As a writer, Wallace has a lot working for him: his pacing is perfect, his descriptions are thorough without being overly detailed, and he creates characters we care about and yet is never afraid to kill anyone in the service of the story.  It's clear no one is safe in this chillingly realistic novel.

Cryptozoologist Loren Coleman wraps up 2013

Loren Coleman, indefatiguable chronicler of cryptozoology, has published his accounts of significant deaths in the field in 2013, his nomination of cryptozoologist of the year (Dr. Bryan Sykes, who disproved most yeti'sasquatch hair evidence but apparently has discovered there was a brown/polar bear relative in the Himalayan region within historical times and maybe still extant), and the Top Ten Events in cryptozoology in 2013. 

Coleman's Top Ten are:

1. Discovery of the Kobomani Tapir (Tapirus kabomani) and other new creatures (a huge discovery, both in size and in scientific importance.)
2. Sykes' "snow bear" (which may still be a living species: there are mysteries about the bear populations of Asia.)
3. Sightings of "Little people" (may be related to the "hobbits" of Flores and/or the orang-pendek, the almost-proven ape of Sumatra, though these new reports seem to concern creatures SO little (20 inches tall) as to be hard to accept as any real animal.)
4. Mystery hominids found through DNA to have interbred with ancient humans
5. A spate of lake monster sightings, plus a "sea serpent" off Maine (I didn't find anything new or compelling in the lake monster cases, some of which were hoaxes: The Maine sea creature is kind of interesting, though it MIGHT have been a swimming moose "blown up" by excitement and the difficulties of estimating sizes across water.)
6. An out of place animal of unknown origin, a leopard, killed in Indiana (a good reminder that people reporting animals that "can't be there" can be right.)
7. Person shot while running around looking for Bigfoot (I'm amazed this didn't happen long ago.)
8. Discovery Channel's fake Megalodon shark documentary, which a lot of people still think was real
9. Interesting "snowman" footprints from Russia (In this entry Coleman mentions a related topic, the ridiculous Ketchum sasquatch DNA claims.)
10. Another sign of crypotozoology in popular culture: Safari Ltd's "Cryptozoology Toob" of small animal models.

Loren does a lot of things with his Top Ten that I like. He doesn't restrict it to events which marked progress: he picks out the most newsworthy even when they involve casting doubt or disrepute on crypytozoology.  He doesn't focus narrowly on reports and evidence: he understands that, however many of us like to think about this in scientific terms, the fact is that science, culture, and media are inextricably intertwined in the modern world.  While Loren tends to be more accepting of sighting reports than I sometimes think warranted (he classes about 80% as mistakes and hoaxes: I think the figure works out to be higher), and we disagree on the possibility of some creatures (we will not, ever, find a giant long-necked mystery animal in a lake), he is more cautious than some cryptozoologists and is willing to call out a hoax as a hoax (e.g., Ketchum). 

So congratulations, Loren, and Merry Christmas!

ADDED: Loren pointed out a a couple of mistakes I'd made in this post (my fault: I didn't quality-check it) and asked if I really thought I could be so certain about long-necked lake monsters. I am, and the rejection of that possibility is now, according to Loren, known as Bille's Dictum.  I''ll "own that," as my daughters would say.  Thanks, Loren.

New mammals - and one is a BIG one

First, we have four small mammals from Africa - the Democratic Republic of the Congo, to be exact. From one forest we have two new shrews and two new bats - small, yes, but important.

Then, we have a big one. This new tapir from Brazil, at over 100kg, is the largest new species of land mammal described since - well, a long time. Vietnam's saola is reportedly about 100kg.  Depending how one counts reclassifications (and which reclassifications and taxonomic "splitting" events one counts), it might even be the biggest since the huge wild cattle species called the kouprey came out of Cambodia in 1937.
So, yeah, it's certainly the biggest mammal discovery of the 21st century. And it should serve as a wake-up call reminding us that there is still a lot  to find in the remote places of the world. Espcially the Amazon, where Dr. Marc van Roosmalen has described several new species, including the 50-kg giant peccary, and reports several more large mammals seen but unclassified.
Here's the formal description. This animal is the fifth living species of tapir (there are some disagreements over tapir classification, but this animal is distinct: there's no doubting it).
So, wow.

The Moon and Mars

OK, maybe the most exciting era of space exploration - when humans stepped on the Moon -is long past.  But what's going on right now is pretty darn amazing. 

First NASA reported that there's more and more evidence for fresh water - even drinkably clear water - in the Martian past.  There's even a hint - just a hint, so far, but tantalizing - that it sometimes still does.

Then, of course, we have the third nation ever to land a probe on the Moon.  Not just a lander, but a rover.  China's feat, using largely indigenous technology (there's some traceability to Russian tech, but that's receding into history), captured the biggest worldwide space headlines since the Mars rovers.  It is, without doubt, a major step toward the goal of sending a human - a feat that would, in popular opinion at least, make China the predominant nation in space exploration.  A rover with the wonderful name of Jade Rabbit is making the first tracks (aside from outright collisions) in the lunar surface since Apollo 17 lifted off.  Amazing. Congratulations to China's engineers - and frankly, shame on the space leadership of the US - it's not that we're not capable of this, we clearly are, but we've chosen to let the headlines go to a rival power.  I don't think we have any idea yet of the implications.

The mission, including the 120-kg rover, was launched on a Chinese Long March 3B on 1 December.

Florida Panther: cat on the edge

Some moron killed a Florida panther, which is not only illegal but a very big deal when there may only be a hundred of them (and there were many fewer than that before conservationists, in a last-ditch measure, brought in a few healthy cats from Texas to strengthen the gene pool). 
The Florida panther has always lived on the edge, hemmed in by development, threatened by hunting (which used to be legal), and increasingly desperate to find mates and food.  The invasion of large constricting snakes competes with them for food in the southern half of the state.  The cat's legendary elusiveness hasn't helped it in the modern age: there are still roadkills every year. (Something I have pointed out in debates over why we don't have a dead sasquatch: if they exist. We SHOULD have one by now.) Anyway, the penalties for killing a Florida panther are severe, and one knucklehead was convicted of killing one in 2009 with a bow and arrow.
Jeff Corwin described an almost surreal sighting in his book 100 Heartbeats: "seemingly in slow motion, it floated to the ground...it was darker than panther's I'd seen in photos, more charcoal than sage... (afterwards) I couldn't stop thinking about the way the panther had seamlessly, effortlessly disappeared without turning a leaf."
Let's keep those few hearts beating.

New species: all discoveries count

We haven't found any new large land mammals for several years. We have found birds, sharks, dolphins, and other "major" animals, though. 
So does something as seemingly tiny as finding a new limpet feeding on the beak of a dead octopus matter?
It does.  Here's the story
Off Antarctica's Pine Island Bay (no, I don't know how it got the name: there are certainly no pine trees.  Maybe an early explorer lost an air freshener there) is the Amundsen Sea, a little-known corner of the great Southern Ocean. A team of biologists from the British Antarctic Survey made an expedition here in 2008 and just now published their findings. (That's not that unusual: it can often take years to determine whether a specimen is a new species: this team found more than 30.)
Why does it matter? First, we need as complete a catalog as possible for conservation.  Second, small animals can be very important in the ecosystem: ask the mighty blue whale, which harvests the dense herds of krill in this ocean, how important tiny shrimplike crustaceans are.  (You could say the blues have a license to krill.) Third, the animals found in an area are major clues to how the ecosystem functions there: scientists found that, unlike neighboring seas, the mobile echinoderms like starfish, rather than sponges, dominated the sea floor.
So let's keep looking.
Katrin Linse, said:
"Unlike many other seas around Antarctica, the Amundsen Sea shelf was not dominated by large sedentary sponges but instead by mobile echinoderms (starfish, urchins, brittlestars and ) and a community of similar animals which inhabit the on-shelf basins.
The Amundsen Sea is an area of rapid change due to ice shelf breakup. Until now we knew nothing about the benthic fauna living here. Our recent study gives us a first insight into the biodiversity of this region and can serve as a baseline to observe future changes.
At least 10% of all the species collected are new to science, and this figure is likely to rise with further genetic identification. "

THANKS TO Robert Twomley for the post on this that drew my attention
