The ALBATROSS (9 letters) is not in the Official Scrabble Dictionary but it is in the Tournament dictionary. At nine letters, there needs to be something like an AL or a BA free on the board that one can play through, ad the appropriate letters to do so.
Adult ALBATROSS can have a WINGSPAN of over 14 feet. They find it very difficult to take off, but once in the air can stay in the air for weeks at a time, and will often circle the globe.
There are 14 species of ALBATROSS and all of them are endangered to some extent.
