Japan seems just a little more terrifying with discovery of local leech’s superpower
Posted on January 27, 2014
Japan is rightfully billed as being an extremely safe country, and for the most part this extends to its natural environment. Lacking the wolves of Europe and North America, the lions and hippopotami of Africa, and the poisonous everything of Australia, there really isn’t a whole lot lurking in the Japanese animal kingdom that frightens us.
Or at least there wasn’t, until we heard the news that Japan is home to a species of super leeches that can even survive being frozen.

The bone-chilling discovery of the boneless creature’s superpower was made by a team of researchers including members from Tokyo University of Marine Science and Technology. Oddly enough, scientists first stumbled across the shocking capabilities of the ozobranchid leech by accident while examining a turtle that had been frozen at minus-80 degrees Celsius (-112 degrees Fahrenheit) for half a year. Why researchers happened to have a frozen turtle lying around remains unclear.
Ozobranchid leeches prey on Chinese pond turtles (also known as Reves’ turtles, which can be found in both China and Japan), and as the reptile thawed, scientists discovered the leech attached to it begin squirming about. We can’t help but feel a little sorry for the leech, which woke up from six months of cryo-sleep to find its mouth wrapped around a dead animal.
Intrigued by the leech’s cold resistance (or perhaps going all-out in their attempt to kill the beast once and for all), the team froze dozens of the invertebrates with liquid nitrogen, keeping them at a temperature of minus-196 degrees Celsius for 24 hours. Other experiments showed that the leeches can survive being frozen at minus-90 degrees for over two and a half years.
The exact way by which the ozobranchid leeches can survive in such harsh conditions is still a mystery, but discovering how is the next order of business for Toru Suzuki, one of the team members and a professor at Tokyo University of Marine Science and Technology. If the leeches’ cold resistance can be duplicated, Suzuki says the method could be used for improvements in transplant organ storage and frozen food production.
