"Creepy Cousins:
A leech is a close relative of the earthworm.",
" Little Suckers:
There is a suction cup at the head and at the tail of the leech.",
"This Saliva Keeps You Alive:
Long ago, leeches were used to heal patients. Today, doctors are finding that leeches are useful in sucking out blood around wounds to prevent swelling.
The leech's saliva contains a type of anesthetic that prevents pain and also keeps the blood from clotting.",
"A Warm Meal:
How does a ground leech detect its prey? Shadows and warm objects will excite them, at which time they will stand on end, waiting for their prey.",
"That's What I Call Focus:
When feeding and mating, the ground leech becomes so desensitized that you could cut off its rear-end and it would continue on its business.",
"Lots-a-Leech:
In the tropics of South America, leeches live in dense populations of 50 per square yard.",
"Sneaky Suckers:
Leeches are thinner when hungry and because they are only an inch long, they can penetrate stockings and clothing.",
"Not My Nose!
Horse leeches from Europe, Asia and India will crawl into a mammal's nose and as they drink, move further into the throat.
They will attach and feed there for months, swelling to the point where the victim often suffocates.",
"It's Rainin' Leeches:
When it pours in the rain forests of Australia these creatures will slither into the trees. Then they will drop down on unsuspecting passersby!
When a leech drops down onto a passing host, the host doesn't realize what has landed - it feels like a raindrop.
The leech will then attach to its host, inject an anesthetic and an anticoagulant, then begin to feed on the host's blood.",
"Big Mouths:
A leech has three jaws that work back and forth during the forty minute feeding process, leaving a star-shaped scar on its victim.",
"Blood Belly:
After a full meal the leech can expand up to eleven times its normal body size.
Young leeches feed on frogs, because their jaws are still weak, and the frogs skin is easier to penetrate."];
