So, there was nothing on regular tv last night so I had to switch it to public tv. And again found a NOVA show, this time about cuttlefish. They are the coolest creatures. I've seen one scuba diving and it's just fascinating to watch. What I didn't know is that if you let them get used to you, which doesn't take long, you can follow them around. They can change to any color or pattern imaginable. And apparently they are smart. The show talked about some experiments they have done to test their intelligence, and while I had to go to bed early to try and sleep, I saw they made it to the second stage of problem solving - meaning linking two issues. So for instance to get out of a maze they had to learn two things, and they did. They and octopi have the largest brains of invertebrates.
Oh, and even more interesting is the mating game. Females are very picky. While some/many male cuttlefish are huge (3 feet long) and will fight over a female, there are smaller males that make themselves look like females so they can get through the fighting bullies and be successful in mating. Way cool.
So, there's your science for the day.
