A constant unverifiable run of giant eels easily mistaken for monsters or dinosaurs for past 1450 years?

Of all the "creatures of legend", Nessie was the one I wanted to be real, my infatuation with Dinosaurs and all.

There's been no hope of that in my mind for about 3 and a half decades now, but it sure was fun to imagine the possibilities.

We, of course, know everything about that monster, everything we need to know anyway: The Private Life of Sherlock Holmes - Trailer - YouTube 

The people of Scotland have long held a strong respect for water spirits and the Fae. 'Nessy' may well be something of an eyebrow-raiser for those with a sensible disposition. However, most of the over 30K Loch's in Scotland have some associated beastie. Loch Ness just has the most international interest. Loch Morar has a reported, equivalent as yet unidentified creature living in it and has done for decades. 

Scotland/Wales and Ireland managed to hold on to their pagan roots a little longer than most.  

Edit: "reported".
