Katakana spelling is standard; usually written in kana.
Kanji spelling exists but is rarely used; the katakana form is strongly preferred.
Compound of ガラパゴス (Garapagosu, 'Galápagos') + ゾウガメ (zōgame, 'giant tortoise'). The katakana spelling reflects the loanword origin of the place name and the usual kana representation of the animal name.
