Has it been thought that this animal actually came from the water? As in, is a water-living animal?
By looking at it, it has no features of a fish, but it looks like it may be able to swim quite well by the looks of it's limbs and 'paws'. Actually, looking at it, it looks like an oversized racoon?
*Just did research*
Yeah, it looks like it COULD be a large racoon. Evidence found below:

But yeah, continue discussion! I'm interested

Peace!
