Concerning the link,I will fix it a little later,sorry about that.
Monty,I mean no disrespect,but to me,it looked like the GPO was much larger than the shark.Now,I'm a novice here concerning marine biology,so perhaps you can elaborate on..
1)Is indeed the shark larger than the GPO?
2)If so,then it must be that cephalopod weight/mass is difficult to predict from just looking at its diminsions.
3)Or.....Perhaps I may need glasses.
Again,I'm just a beginner here,so don't be offended by my "ignorant,but learning" questions.
