Nessie of the North:
Is Alaska's Iliamna Lake monster a huge sleeper shark?
Bruce Wright | May 01, 2012
For years, legendary tales from Scotland and Western Alaska
described large animals or monsters thought to live in Loch Ness and Lake
Iliamna. But evidence has been mounting that the Loch Ness and Lake Iliamna
monsters may, in fact, be sleeper sharks. Two exceptionally large Arctic sharks
ply northern waters -- Greenland sharks and the Pacific sleeper sharks. During
the last few years, scientists have documented Greenland sharks using the St.
Lawrence Seaway, lending further credence to the hypothesis that some sharks
can survive in freshwater. Bull sharks are also known to swim in fresh water,
but this species needs warmer waters.The idea of sharks possibly using Loch
Ness is not new; that's long been one of the hypotheses explaining the Loch
Ness Monster. But until now, nobody has suggested sleeper sharks, perhaps
because they're secretive and so rarely seen.
