Description: A thick-bodied, slow-moving snake with a flattened, upturned “nose.” Color is variable some have dark spots and blotches on a yellow, orange, or brown background, but other specimens are solid black, brown, or olive with little or no visible pattern. Easily identified by defensive behavior (see below). Adult length: 20 to 40 inches.
Habitat and Habits: A snake of open, sandy woodlands – found in the wooded dunes of western Michigan. The upturned snout is used to burrow after toads, a favorite food. When threatened, hognose snakes puff up with air, flatten their necks and bodies, and hiss loudly. (This has led to local names like “puff adder” or “hissing viper.”) If this act is unsuccessful, they will writhe about, excrete a foul smelling musk, and then turn over with mouth agape and lie still, as though dead. Despite this intimidating behavior, Hog-nosed snakes are harmless to humans…
Range and Status: Though recorded from most of the Lower Peninsula and the southern tip of the Upper Peninsula, Hog-nosed Snakes are most common in the western and northern LP. Their numbers have declined in many places, in part due to persecution by humans who mistakenly believe they are dangerous.

In Season of the Massasauga Rattler!, Jonathan Schechter writes that the massasauga likes our sun-soaked trails in the waning days of summer and early autumn, so you may catch a glimpse of one if you’re out and about in Lower Michigan. The Michigan DNR page on the Eastern Massasauga Rattlesnake (Sistrurus catenatus catenatus) explains:
Michigan’s only venomous snake is a rare sight for most state residents. Historically, they could be found in a variety of wetlands and nearby upland woods throughout the lower peninsula. During the late spring, these snakes move from their winter hibernation sites, such as crayfish chimneys and other small mammal burrows in swamps and marshlands, to hunt on the drier upland sites – likely in search of mice and voles, their favorite food.
Females give birth to 8 to 20 young in late summer. The young snakes have a single “button” on their tails; a new rattle segment is added at each shedding of the skin, which occurs several times per year.
The massasauga can be characterized as a shy, sluggish snake. Its thick body is colored with a pattern of dark brown slightly rectangular patches set against a light gray-to-brown background. Occasionally, this coloration can be so dark as to appear almost black. The belly is mostly black. It is the only Michigan snake with segmented rattles on the end of its tail and elliptical, (“cat like”) vertical pupils in the eyes. The neck is narrow, contrasting with the wide head and body and the head appears triangular in shape. Adult length is 2 to 3 feet.
These rattlesnakes avoid confrontation with humans; they are not prone to strike – preferring to leave the area when they are threatened. Like any animal though, these snakes will protect themselves from anything they see as a potential predator. Their short fangs can easily puncture skin and they do possess a potent venom. It is best to treat them with respect and leave them alone. The few bites that occur to humans often result from attempts to handle or kill the snakes. Any bite from a massasauga should receive prompt professional medical attention. When compared to other rattlesnakes found in the United States, the massasauga is the smallest and has the least toxic venom.
Massasaugas are found throughout the Lower Peninsula, but not in the Upper Peninsula (thus there are no poisonous snakes on the Upper Peninsula mainland.)
They stress that Massasaugas are listed as a “species of special concern” and are protected by state law, so don’t kill or harm them. Read on for more including some lookalike snakes.
Jonathan adds that almost all rattler bites are on the dominant hand of the offending human! He took the photo above two years ago on a popular Oakland County hike-bike trail and notes that much of Oakland County is ratter habitat.

The Michigan Department of Natural Resources page on the Northern Water Snake says:
Description: A water snake with dark bands or blotches on a light brown or gray background color. Some old adults may appear solid black or brown. The belly is white with reddish half moon shaped markings; some specimens have an orange belly speckled with brown or black. (The endangered Copper Bellied Water Snake has an unmarked reddish or orange belly.) Adult length: 2 to 4 feet.
Habitat and Habits: These snakes inhabit the shorelines of lakes, ponds, or streams. They swim well, seeking food (frogs and fish) and safety in the water, and often bask on objects hanging over the water. Water snakes are not venomous, but will bite if cornered or handled. They are sometimes mistakenly called “water moccasins” (which are not native to Michigan).
Reproduction: Females give birth to their 7 to 9 inch young in late summer. There are 8 to 48 babies in a litter. The young are gray or brown with bold black bands.
Range and Status: Northern water snakes are found throughout the Lower Peninsula and the eastern Upper Peninsula. Needless persecution by humans has eliminated water snakes from many places where they were once common.
The DNR’s Michigan Snake Page adds that there are just 17 species of snake in Michigan, so do what you can to protect this snake and its kin.

“I liked to go on the road and catch the blue racers and sort of scare my brothers,” she said. “I’d drape them around my neck and around my wrist. I was the ultimate tomboy when I grew up here in Manistee and I loved the Great Lakes. “
~Ann Romney recalling her Michigan childhood (article)
While Mitt Romney’s “the trees are the right height” memories of Michigan drew some laughter, I doubt that anyone would laugh at tomboy Ann Davies with a couple of blue racers draped around her arms.
A large gray or blue snake with smooth scales. The head is usually darker than the body, though the chin and throat are white. The belly is light blue or white. Young racers are grayish, with a pattern of darker blotches and spots. Adult length: 4 to 6 feet.
Racers inhabit a variety of places, including open woods, meadows, hedge rows, marshes, and weedy lake edges. They are alert, active snakes that may climb into low bushes to escape enemies. These snakes feed on rodents, frogs, smaller snakes, birds, and insects. Although they will bite if cornered or grabbed, racers are not venomous.
Females lay 6 to 25 eggs in rotting wood or underground during June and July. The young racers hatch in late summer and, as noted above, are colored differently than the adults.
Racers have been found through most of the Lower Peninsula (except the northernmost sections) and the southern tip of the Upper Peninsula. Once common, their numbers have fallen in many places. Needless persecution by humans as well as habitat loss are probable factors in this decline.
The Coluber constrictor Eastern Racer entry from Animal Diversity Web says that the blue racer is one of several different racer subpopulations and adds a lot more information and photos including that in the wild, racers have been known to live over 10 years. You can also watch a cool video of a BIG blue racer by the Saline Snake Guy.
d charvat writes that they saw this good-sized blue racer while hiking in the Middleville MI state game area. Check it out background big and see a lot more cool shots from out and about in their slideshow.

Aaron writes that he spent an entire summer tracking 18 of these snakes around the park and watching their habits and where they went throughout the season. Lots of fun trekking through swamps, up hills, through shrubbery, etc. You can see more of his rattlesnake photos (slideshow) including a great shot of the rattler’s fangs.

The Michigan DNR says that the Eastern Massasauga Rattlesnake (Sistrurus catenatus catenatus) is Michigan’s only venomous snake. They say that Massasaugas are found throughout the Lower Peninsula, but not in the Upper Peninsula and that they are becoming rare in many parts of their former range, due to wetland habitat loss and persecution by humans. After reading Wisconsin’s very excellent page on the Massasauga Rattlesnake I’m also thinking that wild pigs are accounting for some of that drop. Remember that they are classed as an Endangered Species so don’t kill them! Here’s a few tidbits:
- They say that although drop for drop the massasauga’s venom is more toxic than the timber rattler, with a smaller volume of venom, their bite would probably not cause severe harm to an adult human.
- The adult massasauga is usually two to three feet in length.
- “Massasauga” means “great river mouth” in Chippewa, so named because it is usually found in river bottom forests and nearby fields. Massasaugas are characteristic of mesic prairies and lowland places, such as along rivers, lakes, and marshes.
- The infamous rattles are actually modified epidermal scales with a bony core. Each time the snake sheds its skin a new “button” is added to the rattle, therefore these rattles are not an indication of age, but the amount of times the animal has shed its skin. Massasaugas can shed their skin between 3 and 5 times a year, depending on their health and growth rate. The rattles are believed to serve as warning communications to predators. The rattle produces a buzzing sound similar to that of a grasshopper or cricket.
- It is interesting to note that rattlesnakes can control the injection of venom when biting. Medical experts familiar with snake bites indicate that up to 60% of all snake bites to humans by poisonous snakes are “dry” bites containing no venom.
- Massasaugas are preyed upon by raccoons, hogs, skunks, foxes, hawks, and eagles. They in turn will eat cold-blooded prey, such as frogs and other snakes, but they usually prefer warm-blooded prey like mice and voles.

The Michigan DNR’s page on the Eastern Garter Snake (Thamnophis sirtalis) says that the Eastern Garter is Michigan’s most common snake, inhabiting both peninsulas and even urban areas. Wikipedia notes that they are often mistakenly called garden snakes or gardener snakes and the UM Animal Diversity Web entry for garter snakes adds more info and lots of photos and says that although there are very rare cases of allergic reaction from bites from people handling garter snakes, these reptiles deserve their reputation as a harmless and beneficial low-level predator. Be warned if you handle them that their main defense is a stinky secretion!
This picture is part of a cool set of photos from the Bald Mountain Recreation Area (slideshow). Alanna also commented that she thinks snakes are cool. If you do too, you’ll probably enjoy the Snakes of Michigan page from Snaketamers. It lists Michigan’s 18 species of native snakes (with photos). You can also check out the listing of Michigan’s Snakes from the DNR.

May 23rd is World Turtle Day and Michigan is home to 10 native turtle species. I’ve now profiled 7 (most with Nick’s awesome photography), and you can get the full list at one of the most popular posts on Michigan in Pictures: Know Your Michigan Turtles.
Graptemys geographica (Common Map Turtle, Northern Map Turtle) from the University of Michigan Animal Diversity web says (in part):
Common map turtles get their name from the markings on the carapace. The light markings resemble waterways on a map or chart. The lines on the carapace are a shade of yellow or orange and are surrounded by dark borders. The rest of the carapace is olive or grayish brown. The markings on the older turtles may be barely visible because of darker pigment. The carapace is broad with moderately low keel. The hind of the carapace is slightly scalloped shaped due to the scutes. The plastron of an adult map turtle tends to be plain yellowish color. The head, neck and limbs are dark olive, brown or black with thin yellow, green or orangish stripes. There is also a oval spot located behind the eye of most specimens. There is sexual dimorphism in size and shape. The females are much larger than the males…
The common map turtle is dormant from November through early April. Most of that time is spent under the water, wedged beneath submerged logs, in the bottom mud of a lake or in a burrow. They have been known to change locations in the middle of the winter. They are avid baskers and they bask in groups. They are diurnal, active both in the day and at night. They are also a very wary animal, at the slightest hint of danger they slip into the water and hide. During courtship the male initiates by tapping his long claws on the front of the female but few details are known.
Common map turtles are omnivores. The feeding always takes place in the water. The adult females, due to their large heads and strong jaws eat larger prey than the males. The females consume snails, clams, and crayfish. The males eat aquatic insects, snails, and smaller crustaceans. Both are also known to eat dead fish and some plant material.

I love old books, and was happy to find Wild Flowers Worth Knowing by Neltje Blanchan, a 1917 book that is available online through Project Gutenberg. The entry for Yellow Adder’s Tongue; Trout Lily; Dog-tooth “Violet” (Erythronium americanum) is a good example of the descriptive & endearing turns of phrase you often find in books from another age:
Flower - Solitary, pale russet yellow, rarely tinged with purple, slightly fragrant, 1 to 2 in. long, nodding from the summit of a root-stalk 6 to 12 in, high, or about as tall as the leaves. Perianth bell-shaped, of 6 petal-like, distinct segments, spreading at tips, dark spotted within; 6 stamens; the club-shaped style with 3 short, stigmatic ridges. Leaves: 2, unequal, grayish green, mottled and streaked with brown or all green, oblong, 3 to 8 in. long, narrowing into clasping petioles.
Preferred Habitat - Moist open woods and thickets, brooksides.
Flowering Season – March-May.
Distribution – Nova Scotia to Florida, westward to the Mississippi.
Colonies of these dainty little lilies, that so often grow beside leaping brooks where and when the trout hide, justify at least one of their names; but they have nothing in common with the violet or a dog’s tooth. Their faint fragrance rather suggests a tulip; and as for the bulb, which in some of the lily-kin has toothlike scales, it is in this case a smooth, egg-shaped corm, producing little round offsets from its base. Much fault is also found with another name on the plea that the curiously mottled and delicately pencilled leaves bring to mind, not a snake’s tongue, but its skin, as they surely do. Whoever sees the sharp purplish point of a young plant darting above ground in earliest spring, however, at once sees the fitting application of adder’s tongue. But how few recognize their plant friends at all seasons of the year!
Every one must have noticed the abundance of low-growing spring flowers in deciduous woodlands, where, later in the year, after the leaves overhead cast a heavy shade, so few blossoms are to be found, because their light is seriously diminished. The thrifty adder’s tongue, by laying up nourishment in its storeroom underground through the winter, is ready to send its leaves and flower upward to take advantage of the sunlight the still naked trees do not intercept, just as soon as the ground thaws.

Dan Austin of HistoricDetroit.org has an incredibly comprehensive history of the Belle Isle Aquarium. He writes, in part:
Clarence M. Burton, in his history on the city of Detroit, attributes the idea of an aquarium to Rep. David E. Heineman, who had visited Naples, Italy, and studied that city’s Anton Dorhn Aquarium.
…The firm of Nettleton & Kahn drew up the plans for the buildings. The building’s price tag: $165,000 (about $4.06 million today). At the time of its opening, the aquarium was among the six largest in the world. Its high-tech equipment allowed for the keeping of both seawater and fresh-water marine life and the keeping of the right water temperatures in the tanks. The water was recycled through the tanks because, it was said, that fish survive better in water they’ve been in before. Originally, a 8,531-gallon center tank with a railing around it occupied the center of the building. It was topped off with filtered water that snaked through 5 miles of pipes.
Kahn outfitted the interior with sea-green glass tiles to give visitors the feeling that they were in an underwater cavern. Forty-four tanks filled with critters from the Great Lakes and the world’s oceans line the walls. Combined, the tanks contained 5,780 gallons of water. Magnificent pillars and other details compliment the soaring arched ceilings, as high as three stories in the center of the building. A classroom sits near the main entrance.
The front of the slender, brick building features an elaborate Baroque entrance with carvings of dolphins and a grotesque of Neptune, the Roman god of water. In the center is the city’s seal showing the two maidens and the Detroit motto, “Speramus meliora; resurget cineribus” — “We hope for better things; it will rise from the ashes.” Below that, the word “aquarium” is carved in capitalized, bold letters. The intricate details are sometimes masked by robust ivy that covers the front of the building.
When opening day finally came on Aug. 18, 1904, Detroiters were champing at the bit to take a peek. By the time dawn rolled around, the line numbered into the thousands and stretched from the aquarium’s front door all the way, across the bridge, back to East Jefferson Avenue. More than 5,000 people visited on the attraction’s first day. Some half a million would gaze into its tanks its first year.
Read on for much more that takes you through nearly a century of operation as one of the largest freshwater collections, decline in the latter part of the 20th century, shuttering in 2005 and re-opening in 2012. Definitely check out his gallery of Belle Isle Aquarium photos too!
Today the aquarium is run by the Belle Isle Conservancy and open on Saturdays from 10 AM – 3 PM with free admission and parking.
