We saw green, slimy, slippery groups of seaweed. They had pocket-like "leaves" and they were laying on rocks near the spot where the freshwater of The Presumpscot River meets the saltwater of the Atlantic Ocean (brackish water). It was low tide moving into high tide. The fresh water was murky and it was mixing with the clear, blue salt water. The spots where the waters were mixing were white and foamy.

The frog that we saw was a very well camouflaged little critter. I didn't get a good look at him, but he was sort of a muddy green.
The vole that we found was a brown color with a white belly. Unfortunately, when we found the vole, it was already dead. We thought it was because it had been picked up by another animal, intending to eat it, then was spooked and dropped the vole. It had its intestines coming out, and flies were already buzzing all over it.
This animal was a very large adult, probably about five inches long from top to bottom. It had a white back, with some odd patterns in black that almost looked like skulls. The spider was waiting in hopes that some helpless animal would come by to make a tasty meal for him.
