How heavy does an average squid weigh?

Teuthowenia pellucida, also known as the Deep Sea Glass Squid lives in the deep seas of the Southern Hemisphere. It has light organs on its eyes and it is able to roll into a ball, just like a hedgehog. http://www.exploretheabyss.com/photo/gallery/gallery/biolumin/images/TeuthoweniaTopView.jpg (Image from: www.exploretheabyss.com)
