Freshwater Basses
Note how the mouth of the Largemouth extends under the eye, while that of the Smallmouth stops short of it. A lot of fishermen seem to think everything they catch is a Largemouth.

Bass are not suitable for the aquarium except in solitary confinement. They are extremely aggressive, and will kill any tank-mates.

Orbweavers
If you are trying to escape the sun in the shade of overhanging tree branches, you are inevitably going to get spiders in the boat. These are almost entirely harmless orbweavers - they are not aggressive and don't bite, and are not poisonous to humans, at least no more poisonous than a honey bee. That said, our brains are programmed at the most basic level to fear spiders, and I don't like them any more than anyone else. Just calmly knock it out of the boat.
