Ugh, I hate that term.  "Semi-aquatic" carries about as much information
as does "semi-cursorial".  What is the cutoff point between being
"semi-aquatic" and being "terrestrial, but likes to wade"?

Perhaps Durand should have avoided the issue entirely and instead used
the word "piscivorous" to describe Spinosaurus' hypothesized lifestyle?
