IS crayfish really primitive ?

I have noticed changes in behaviour of my crays after some time of having them. when i first got them they were really shy and were hiding almost all the time or when i came close to the tank they were running to the closest hiding spot, now everytime i Come to feed them or check on them, they crawl out immediately even without knowing If i feed them or not and always go to the side of the tank i stay close to, trying to climb the Wall, i have noticed this behaviour especially with older crayfish, have anyone noticed it too ?

Is something wrong?

My cray keeps trying to climb the side of the tank. Its full to the top with water so I know he won't be able to get out, but does he need more oxygen? I have a decent sized air stone in there to make sure he gets what he needs, but I'm unsure if it is enough. He hasn't tried to climb to the top before today. Normally he just sits at the bottom under his log. Any advice?
