There is a good story to the scientific name for the Green Treefrog, Litoria caerulea. The first specimen was sent back to Britain in the 1780s by the then Surgeon-General, John White, of the penal colony, New South Wales. It was preserved in spirit-of-wine, which turned the frog's green into bright blue. Hence the Latin designation 'caerulea', bright blue, which they thought was its true colour back in merry England. Interestingly, White hated his posting and wrote of Australia as, "a country and place so forbidding and so hateful as only to merit execration and curses."
