Ive seen small rays in huge aquariums climb walls and larger rays in smaller
aquariums not climb walls. Also seen large rays climb walls in huge very
large aquariums. Mikes 4000 gallon tank video is an example of that.
Bears, lions and such patrol and are territorial, covering 100s of square
miles, thus giving them the basic instinct to want to roam looking for intruders
or females in heat.
While rays, might travel in a linear path up and down a river system, I don't
believe it is there basic instinct to patrol this type of range. Of course I could
totally be wrong.
All I do know is that I have a larger female who never climbs, a small male
who seldom climbs and a small female who constantly climbs. Are they playing,
exercising or just depressed I don't know, I guess we will never know unless
we can read the minds of animals.
I do know they are very intelligent as my larger female has learned to shove a large round
rock around looking for food that may have settled around it.
