Half a century ago, Belgian Zoologist Bernard Heuvelmans first codified cryptozoology in his book On the Track of Unknown Animals.

The Centre for Fortean Zoology (CFZ) are still on the track, and have been since 1992. But as if chasing unknown animals wasn't enough, we are involved in education, conservation, and good old-fashioned natural history! We already have three journals, the largest cryptozoological publishing house in the world, CFZtv, and the largest cryptozoological conference in the English-speaking world, but in January 2009 someone suggested that we started a daily online magazine! The CFZ bloggo is a collaborative effort by a coalition of members, friends, and supporters of the CFZ, and covers all the subjects with which we deal, with a smattering of music, high strangeness and surreal humour to make up the mix.

It is edited by CFZ Director Jon Downes, and subbed by the lovely Lizzy Bitakara'mire (formerly Clancy), scourge of improper syntax. The daily newsblog is edited by Corinna Downes, head administratrix of the CFZ, and the indexing is done by Lee Canty and Kathy Imbriani. There is regular news from the CFZ Mystery Cat study group, and regular fortean bird news from 'The Watcher of the Skies'. Regular bloggers include Dr Karl Shuker, Dale Drinnon, Richard Muirhead and Richard Freeman.The CFZ bloggo is updated daily, and there's nothing quite like it anywhere else. Come and join us...

One of the inconveniences of our past explorations in the jungles of Sumatra have been leeches. One evening in 2004, whilst on our way to the lost valley, we picked 100 of the little suckers off our legs as we sat around the campfire. I still bear the marks of leech bites from the Sumatran expeditions of 2003-2004 and got some fresh ones this year when I returned.

Jon Hare was particularly repulsed by the creatures and one even found its way into Chris Clark’s mouth! Imagine the horror of a giant leech then. The crawlers in Sumatra were only a couple of inches long but the South American giant leech is 18 inches long!

Haementeria ghilianii inserts a 6 inch proboscis into its mammalian prey in order to drink their blood. This mega leech can live as long as 20 years and was first discovered in 1849. The monster was thought to be extinct since none had been collected since 1893. However, Dr Roy Sawyer discovered a pair in a pond in French Guyana in the mid 1970s, one of these named ‘Grandma Moses’. This individual founded a leech breeding colony at the University of California-Berkeley and produced more than 750 offspring.

More than 46 medical, neurological and natural history research publications were based on data from specimens reared at the breeding colony. Some important discoveries from these offspring include the characterisation and purification of several proteins with an anticoagulant and antimetastatic effect, including hementin, which destroys human fibrin blood clots; charting connection of nerve cells; and functional morphology of salivary and nerve cells. Following its death, ‘Grandma Moses’ was deposited in the collections of the Department of Invertebrate Zoology, National Museum of Natural History at the Smithsonian Institution.

Film of one of these impressive monsters can be seen here
The related Americobdella valdiviana from Chile can exceed 12 inches in length.

Campsite stories are told of a blood-sucking monster near the town of Sharon in Vermont, USA, deep in the Downer State Forest in an 800 acre woodland camp know as Camp Downer. At Camp Downer there is a canoe pond constructed in the 1930s by the Civilian Conservation Corps, and close to an island in the pond a giant leech is said to lurk; a leech weighing over 300lbs!

A story told to scare children at the camp? Who knows? It might be interesting to investigate though.

Somehow, I can't help but think that the author has been reading a little too much of the science fiction of Neal Asher. His works describe a most peculiar alien ecosystem, where one of the dominant life forms is a giant leech, plus a most peculiar viral symbiont which seems happy to infect pretty much any life form it comes into contact with.
