What animal did Pi study in particular and why?

Pi studied the three-toed sloth while writing a thesis for his Zoology major.

My zoology thesis was a functional analysis of the thyroid gland of the three-toed sloth. I chose the sloth because its demeanour-calm, quiet and introspective-did something to soothe my shattered self.
