When I had my house in Ottawa I had a 108 gallon aquarium. In it I bought a pair of fresh water stingrays. A male and female. Aboot 8" round and 18" long with the tails.
They were like puppies. They would slide up the side of the tank to be scratched. This was before cell phones and digital cameras in general and, it pisses me off, all the film stock was lost.
The film is sped up. Chameleons don't change color that fast. I've owned a couple of them and it takes about 20-30 seconds for them to change color. A little less if they're pissed off.

You both fucked up. You trusted me.

Still amazing how they can do that. The whole camouflage defensive strategy in nature evolved over millions of years. Walking sticks, have a lizard that hangs around a tree outside. Perfectly blends in. Even watch him wave around his upper body/ neck like it's swaying in the wind. But changing colors is at the very top of camouflage strategy.

No. It's not. Being transparent is.
Yeah, being invisible is way up there, too. How about one who's defensive strategy is generating electricity to deliver a shock. How in the H does an animal evolve something like that.

Yeah, but invisibility is just a creature evolving over a million years to make itself be seen through. With animals that change colors or generate electricity, they have to evolve an organ in their bodies to do that. How in the H does a line of creatures go down that path.
I haven't read or studied on it, but I think I have a handle on the whole color/electrical defense evolution. Chameleons(color) and electrical eels(electric) are the top tier evolution and the most recent. I thinks it's something much more ancient- going back hundreds of millions of years. Something that started as a simple creature being able to generate an tiny inner electrical/chemical field. One word- Bioluminescence.
