An American Toad Experience

I’ve seen plenty of toads as they were hopping away to escape my foot. But this toad, trapped between me and my dog, froze in its tracks. As I bent down to take its picture, I experienced a mixture of shock, disgust, and concern, for it appeared to have holes in its back, each filled with brown seeds.

That evening, I settled into my comfy armchair to read about toad anatomy. The holes in its back are called dorsal blotches or spots and the “seeds” are actually warts. Toad identification includes counting how many warts are in the spots. One or two per spot and it’s an American Toad. More warts per blotch, then it might be a Fowler Toad. Interbreeding is common between the two species, which probably explains why our toad has one or two warts in most of its spots, but one spot appears to be crowded with maybe five warts. So this is probably not a purebred American Toad (a Yankee?) but one with a bit of Fowler in its past.

The two oval sacs behind the eyes are the parotoid glands that secrete bufotoxin, a substance that ranges from mildly irritating to poisonous, depending on the species. The American Toad’s protective secretion is on the mild side, a fact that for most people is reassurance that their curious dog may vomit, but probably won’t die. But for others, it’s a matter of self-interest, for toad-licking is making a comeback!

Toad-licking is a real thing, but most toad abusers these days milk the glands and then dehydrate the bufotoxin so that it forms a powder that is suitable for smoking. Apparently, the most satisfying hallucinogen comes from the Colorado River Toad. Symptoms of ingesting toad serum include unresponsiveness or having convulsions or vomiting. Yet so many toad users report having a religious experience (“being one with God”) as well as enduring positive feelings that Johns Hopkins University is researching the use of toad venom to treat depression.

Like all good experiences, getting high from smoking toad serum has been overdone. Advice from an addiction center website: If you or someone you know is abusing Toad Venom, there is help available.

Sutures on a White-tailed Deer Skull

White-tailed deer skull

I found this white-tailed deer skull along with other parts of the carcass while exploring off-trail in an area of the woods that was not easy to navigate. In this relative wilderness, the deer had probably been taken down by a coyote or died a natural death.

Although the skull is damaged, the zig-zag markings on the top are beautifully intact. Similar to spalting, which is a network of lines marking fungal boundaries in wood, these cranial sutures mark boundaries between bones.

 

When the deer was young, the sutures were fibrous areas that allowed the bones to expand. They also indicate stresses placed on the skull by chewing. In male deer, the largest sutures (the coronal pair that meander horizontally across the top of the skull) indicate the presence of antlers. The smaller wiggly line in the back of the skull is the lambdoid, and the vertical one extended towards the mouth is the sagittal suture.
