Forensic Leech Solves Oz Case


Eight years ago Peter Cannon tied up a 71 year old woman in her remote Tasmanian home and stole several hundred dollars in cash. Unbeknownst to Cannon, a terrestrial leech (probably Philaemon grandis, endemic to the island) that had finished feeding on him, dropped off while he was in the midst of theiving.

The case remained unsolved until forensic experts extracted DNA from the leech gut contents, and matched fingerprinting profiles to those on record for Cannon. Cannon promptly plead guilty when faced with the incriminating match.

New Leech Species from Jersey


Bill and Carol Ott found a huge leech in a ditch in their backyard in Alloway New Jersey, brought it inside and cared for it. That's a story enough in itself!! "We're just curious people," Carol Ott said.

Beth Wirchansky, a student of Dan Shain's at Rutgers, figured out it was a species new to science, and described it as Haemopis ottorum. Through molecular phylogenetic methods, Wirchansky and Shain corroborated its uniqueness and that its closest relative is Haemopis terrestris.

For the rest of the month, there is a display devoted to Haemopis ottorum, including live specimens, in the lobby of Rutgers-Camden's Science Building!

Congrats Beth.

Leeches in Creation Mythology

Last year I posted the Osage Creation Myth in which Macrobdella decora is prominent.

Remarkably, leeches appear in a wide variety of creation myths.

In the Qu'ran:
“then of that fluid-drop (nutfa) We created a leech-like clot" (Quran 23:14)
"then did he become a leech-like clot; then did (Allah) make and fashion (him) in due proportion. And of him He made two sexes, male and female.”(Quran 75: 37-39).

In the creation myth of the Bengali Munda people in India, the benevolent Sun god Sing-Bonga is married to the Moon and brings forth a tortoise, a crab and a leech to create the land by bringing up soil from the sea bed. – Dalton (1872: Descriptive ethnology of Bengal, p 197). "SingBonga ordered them to bring a lump of clay (hasa) from the depth of ocean. The tortoise and the crab failed to do it. The leech went deep and deep to the ocean and finally found bit clay from the depths of the ocean and gifted it to the Supreme Sing Bonga. SingBonga by his power transformed the bit of clay into the earth. "

In Shinto creation mythology "After the sun and moon, the next child Izanagi no Mikoto and Izanami no Mikoto gave birth to was the leech-child. When this child had completed his third year, he was nevertheless still unable to stand upright." Alternatively: "The child which was born to them was Hiruko (the leech-child), which when three years old was still unable to stand upright. So they placed the leech-child in a boat of reeds and let it float away."

The Great Leech Of Tlanusi'yï

I recently had the opportunity to attempt a face-to-face encounter with the largest and most feared leech of North America.

As described by James Mooney (1891), in his accounts of the Cherokee myths and sacred formulas...

"The spot where Valley river joins Hiwassee, at Murphy, in North Carolina, is known among the Cherokees as Tlanusi'yï, 'The Leech place,' and this is the story they tell of it:

"Just above the junction is a deep hole in Valley river, and above it is a ledge of rock running across the stream, over which people used to go as on a bridge. On the south side the trail ascended a high bank, from which they could look down into the water. One day some men going along the trail saw a great red object, full as large as a house, lying on the rock ledge in the middle of the stream below them. As they stood wondering what it could be they saw it unroll--and then they knew it was alive--and stretch itself out along the rock until it looked like a great leech with red and white stripes along its body. It rolled up into a ball and again stretched out at full length, and at last crawled down the rock and was out of sight in the deep water. The water began to boil and foam, and a great column of white spray was thrown high in the air and came down like a waterspout upon the very spot where the men had been standing,. and would have swept them all into the water but that they saw it in time and ran from the place.

"More than one person was carried down in this way, and their friends would find the body afterwards lying upon the bank with the ears and nose eaten off, until at last the people were afraid to go across the ledge any more, on account of the great leech, or even to go along that part of the trail. But there was one young fellow who laughed at the whole story, and said that he was not afraid of anything in Valley river, as he would show them. So one day he painted his face and put on his finest buckskin and started off toward the river, while all the people followed at a distance to see what might happen. Down the trail he went and out upon the ledge of rock, singing in high spirits:


Tlanu'si gäe'ga digi'gäge
Dakwa'nitlaste'stï.
I'll tie red leech skins
On my legs for garters.


"But before he was half way across the water began to boil into white foam and a great wave rose and swept over the rock and carried him down, and he was never seen again.

"Just before the Removal, sixty years ago, two women went out upon the ledge to fish. Their friends warned them of the danger, but one woman who had her baby on her back said, 'There are fish there and I'm going to have some; I'm tired of this fat meat.' She laid the child down on the rock and was preparing the line when the water suddenly rose and swept over the ledge, and would have carried off the child but that the mother ran in time to save it. The great leech is still there in the deep hole, because when people look down they see something alive moving about on the bottom, and although they can not distinguish its shape on account of the ripples on the water, yet they know it is the leech. Some say there is an underground waterway across to Nottely river, not far above the mouth, where the river bends over toward Murphy, and sometimes the leech goes over there and makes the water boil as it used to at the rock ledge. They call this spot on Nottely 'The Leech place' also.
