Scales or hair?
Most lake monster sightings report "scaly" reptilian creatures. Sleek, shiny scales are reported in almost every sighting.
We have mentioned before that there are many simple explanations for most "lake monster" sightings, among which (besides logs, waves and birds), are otters.
As you can see in the photograph, otter fur when wet clumps together and gives the impression of being scales.
But otters are not monsters nor reptiles, they are furry mammals. Though the photograph shows Canadian otters, Patagonian otters (huillín) are virtually identical and can therefore explain many of the "plesiosaur" reptile-looking monsters seen in Patagonia.
