I figured I'd title this like a really bad biology project…:rolleyes:

I teach bushcraft whenever I can. Here in Ontario, the seasons are incredibly different. And each brings with it different flora and fauna to study, often in great detail. This past June, during the Dragonfly Course (Wetland Bushcraft) was no different!

Where we were camping, was on Rice Lake, on the Hiawatha First Nation reserve (Anishnaube Akii/Ojibway Territory). We spent a lot of our time feasting on cattails and milkweed pods, building fishing weirs, and often getting close to our local neighbour named Chelydra serpentina.

Who? The name when spoken conjure up in my mind, some hideous dragonesque creature from the depths of the darkest waters. Very similar to the descriptions of Cuthulu! And sadly, that stigma often lands upon this beautiful cousin. The Common Snapping Turtle, is native specifically to North America (however can be found in South American countries as well), being found almost as far north as Hudson Bay (though not often further north than Algonquin Park).

While on the Dragonfly course, the student I had with me was very interested in studying these beings up close. Of course, their name was reason enough for him not to get too close! The snapping turtles were found on the banks of the marshlands, right along a backroad, digging nests in the gravel. Snapping turtles rarely leave the waters, usually only the females leave their swamps to dig their nests and lay their eggs. However on occasion the adults (and young) can be found basking in the sun. Though more often they do this by floating on the surface of the water, often to the surprise of a bushcrafter who just fell out of their canoe... :eek:

I carried an Australian styled fishing spear with me during the entire course, complete with an American Indian styled "Atlatl" dart thrower (didn't have the time to make a genuine Woomera to accompany the spear). This is a very useful tool when in the wetlands. I used the butt of the spear to prod one of the females we happened across, to demonstrate to the student their power. She immediately reared up on all four legs, which suddenly seemed a lot longer than I remembered a turtle's legs being. She emitted this strange hiss that didn't seem to come from her mouth, but from the shell (though it was from the mouth, the sound just seemed to echo from the shell). I prodded again, hoping to demonstrate how vicious of a bite these shelled creatures have. Nothing. I tapped the shell, hoping to watch her long neck (which can reach halfway across their body, and sometimes more) lunge out at the spear. Nothing. I rested my spear in front of her, and turned to my student to tell him that usually they were much more aggressive, when suddenly I felt the end of my spear splinter with a loud "SNAP!", I turned in time to see her slowly bring her head back to it's original position. We left her to finish laying her eggs, and went on with our day.

Snapping turtles are omnivorous, and will often scavenge any dead substance in the water, whether it be a dead fish, or rotted plant matter. However, they will actively hunt, feasting on small to medium sized fish, crayfish, mussels, insects, amphibians, rodents such as voles, and reptiles such as snakes and smaller turtles (including infant snapping turtles).

Their relative, the Alligator Snapping Turtle Macrochelys temminckii, whom resides in the southern United States, is much larger than the common snapping turtle, however is not as aggressive as the common. The Common Snapping Turtle is recognized for the deaths of many goslings and ducklings each year throughout Ontario. Adult ducks and geese (even swans) are sometimes found with missing feet or toes, often caused by being maimed by snapping turtles. While heading to the bay where we would be harvesting cattails (Greater Reed-mace), the student and I came across a very large painted turtle, whose shell had a large section missing from it. Still alive, healed and scarred, this old girl was a survivor of a snapping turtle attack. There are countless stories of snapping turtles amputating the digits of people. I was raised with stories from my Ojibway grandmother who witnessed a boy losing a very large section of his heel to a snapping turtle he accidentally kicked while swimming. Though it seems unlikely that an animal that looks so slow could do so, their powerful jaws, and aggressive tendencies give good reason to steer clear when you find them.

Being so vicious, has done some good things for the common snapping turtle. They cannot fully retract their heads into their shells, which other North American turtles can do. Because of this, they are left exposed, and in theory, easy to kill by predators. However, except for the rare otter, and man, Snapping turtles don't really have that many predators. I suppose the other predators learned long ago what my spear learned during the Dragonfly course!

As well, their diet supports their ability to survive in almost any water body in North America. Seeing as I named otters earlier as a predator of the snapping turtle, I'll describe what a park ranger told me when I was learning Bushcraft in Algonquin Park;

Most lakes in Ontario, and North America, can support perhaps 2-3 families of otters (four to six adults, plus their young). The fish after that, will decrease in population, and due to starvation, the otters will have to move, or die. However, that same lake can support up to fifty adult snapping turtles, plus the hatchlings. Why? If it lives/lived, they'll eat it. And seeing as they don't need to eat constantly to survive, they can take long stretches between meals.

Another interesting subject that comes up with snapping turtles and their survival, is their eggs. Ron Brooks, a professor of Zoology, was recorded in Norm Quinn's book "Algonquin Wildlife: Lessons in Survival", of doing research on the nesting and survival rates of snapping turtles. According to the book, unlike other species, like rabbits, which breed a great amount of young but have short lifespan, the mortality rate of adult snapping turtles is very low (disregarding human involvement that is). It is believed that wild snapping turtles can live up to 45-50 years, though this theory is hard to pin down, because after a certain length of time, the turtle's shell scales no longer grow. So measuring the age of the turtle becomes impossible after 45-odd years.

Other species that live long periods of life (moose as an example), give birth to very few young. Often 2-5 in their lifetime. But the Snapping Turtle can lay up to eighty eggs in one season. Females will lay each season. The females can lay eggs for many years of their lives. So that is a lot of eggs!

Odd though, is the fact that the mortality rate of infant snapping turtles is nearly 99.9% of them. Foxes, raccoons, vultures, gulls, ravens, skunks, large mouthed bass, pikes, and other snapping turtles all pose threats to the infants throughout their lifetime. This includes their time in the nest, where foxes, skunks and other critters will sniff out the eggs!

And yet, the turtle's population has never seemed to naturally lower. I say naturally, because human involvement is lowering the population through; hunting, poaching, vehicle collisions with nesting mothers, and the destruction of habitat. But in nature, the snapping turtle populations never seem to lower. Nor do their numbers rise (remember, the babies don't often survive). So in a simple, dramatic way of putting it.. snapping turtles.. just.. don't die... :eek:

Mother turtles will travel extensively over land, to find the perfect soil (sandy or gravel, in warm sunny places) to lay their eggs. If harassed by vehicles, people or other animals, they will abandon a nest in mid-dig, and travel a far distance to dig again. I accidentally bothered one mother enough to make her travel deep into the bush, climbing over metre thick logs, and under fallen trees, just to find a new site. I tracked and followed her at a far distance, and once she found a new nesting site, I left her to do her business.

Native people have had a close relationship with snapping turtles. When the nesting season began, Ojibway youth were sent out to prod the sandy banks of rivers, lakes and swamps with sharp sticks. Once the stick was found covered in yoke, the children would dig up the nests, harvest the eggs and bring them back to the village as treats.

Fishing weirs were often found with snapping turtles within them, and because of this, they frequented the diets of Eastern Woodland tribes (Ojibway, Iroquois, and Menominee). Midden mounds found along the shore of Rice Lake had snapping turtle bones within them from long ago (well over 2,000 years). The meat -according to many Anishnaube elders- comes in seven different textures and tastes, ranging from fish, to tenderized lamb. It's a favoured dish served within the Anishnaube Akii (Ojibway Territory) throughout early summer.

The claws are often found on necklaces, possibles bags, and medicine bundles.

The body, including shell, head and neck, would be carefully sewn shut, filled with birds beaks, wild cherry stones, or even small pebbles or mollusc shells. The neck would be stretched out tightly (again, a long neck), and braced out to dry with hickory or ash splints. Wrapping the braced neck in rawhide, this item was used by many Iroquois holy people as a rattle/shaker. Other native tribes made similar rattles.

The carapace (Top shell) was/is used as a bowl for soups (including turtle soup), and as a berry basket. Other uses for the carapace have included;

-shields used by some tribes during pre-firearm warfare (these shields can still be seen amongst some Northern Traditional dancers),
-drums, if the open side is covered with rawhide and bound tightly, a small hand drum can be produced, though the sound is not very popular
-Bags, If the back is covered with deerskin or fabric, a shoulder strap can be attached and made into a very attractive possibles bag (smaller shells used similarly as belt pouches)

The plastron (Bottom shell) was often scored with flint tools and broken into flat disks, used as pendants, pieces for traps, animal calls, and even as dinner plates. Other uses can include;

-Beads
-goggle lenses (often seen by Malaysian cultures with sea turtle shells, which they scraped thin enough to become translucent).
-playing cards can be made from them. Simply scratch the numbers and suits onto the disks (Primitive Poker anyone?)

The dried heads have been used as decorative pieces for "spirit sticks", and other ceremonial tools.

The Iroquois and Algonquian tribes believed the world rested on the back of a snapping turtle. Due to this, they called their homeland "Turtle Island". Interestingly, if you look at a map of North America, you may just see this. Newfoundland and Alaska make up the front legs. California and Florida are the hind legs. Mexico is that thick serpentine tail. The arctic islands shape beautifully into the head, and the rest of North America is the shell. I find it absolutely beautiful how a native legend suits the geography that well.

The night I got home from the Dragonfly course, I stood barefoot outside in my front door (door closed) having a cigarette (been trying to quit them for a long time now..). I was thinking over the last five days I spent in the wetlands, living next to snapping turtles and ospreys constantly. As I kept playing the days over, I began to get the weird feeling that I was about to get my toes nipped off by a snapping turtle. I quickly finished my cigarette and went to bed. Nine hours later I was awoken by someone screaming at the front door. Apparently they had opened the door, thinking one of our cats was scratching to get in. They opened the door to find this "little" lady there;

Aanii Oz. Welcome back :)

This is really interesting reading. Snapping turtles are probably not the most "glamorous" creatures. But you certainly make it sound like they deserve to continue their lives on their land. You are a very good advocate for their welfare. what I like about your writing is the mix of biology and your "native" knowledge (and I don't mean this in any derogatory way) knowledge that deserve to be recognized.

And fancy finding a snapping turtle scratching at the door! Much better than the local cats!!

Funny that you mention it Jojo, but in my honest opinion, they deserve Canada's respect, and the thanks of all North Americans near any body of water.

They remove the dead, the rotting, and the diseased, by a simple process (eating!), and leave us with healthier waters. If we ever lost the Snapping Turtle, Canadian waters in my opinion would not be as healthy.

I figured if I was to write about them, I had to give fact and history to bring forward their due credit. But I was always raised to humanize the animals we encounter, because they are our relations. So I couldn't neccesarily make Mrs Snapper into a scientific examination alone!

After writing this thread I got a bit inspired, there will be others like it on the way.

Oh, and by the way Jojo... the Ravenwings held up beautifully on the Dragonfly course! Never had carbon steel take to such a humid environment that well before.

In a way, they are a bit like vultures, aren't they. Doing an indispensable job of keeping the land and water clean. Not a very glamorous task, and they don't get enough recognition for it.

To me anyway, this shows how patchy our knowledge is and also that relying on science alone is not always answer enough to the problems we create. I think you look at things with a different perspective and that makes it valuable.

I think you should start a blog, where you keep your writings. Maybe turn them into a book some day.

Glad the Ravenwings are performing well :)

IIRC snapping turtles have turned up in ponds and lakes in the U.K. from time to time.

Jim

Unfortunately, this has not been done on a controlled basis and has even led to the usual sensationalist media interest when a turtle/terrapin was filmed eating ducklings.

I'm sure many remember Teenage Mutant ninja Turtle craze in the 80s? Well, misguided parents bought them for their whinging kids, unscrupulous dealers made a lot of money, and, then the turtles grew, they ended up too big for aquariums. They were dumped in local ponds and have been living quite successfully!

Wonderful creatures...in their own 'native' environment!

That was a very well written piece, combining science and traditional lore. (theres a place for both, isnt there?)
