Animals with the Mostest: Biggest, Fastest, Most...Eyes

Can you name the top animals in each category? Living species unless otherwise indicated. Some are difficult, but full name is usually unnecessary (e.g. 'horse' would be accepted for 'Arabian horse') so guess if you don't know. Feedback welcome!
