🐺Island fox
Saariharmaakettu eli kaliforniankettu eli saarikettu (Urocyon littoralis) on pienikokoinen koiraeläin. Se ei nimestään huolimatta kuulu kettujen Vulpes-sukuun, mutta on niille läheistä sukua. Laji elää luonnonvaraisena Yhdysvaltain Kaliforniassa kuudella Santa Barbaran saarten kaikkiaan kahdeksasta saaresta. Lajilla on kuusi alalajia: kullakin kuudella saarella omansa. Koska saariharmaaketun esiintymisalue on maantieteellisesti syrjäinen, sen vastustuskyky tauteja ja loisia vastaan on jäänyt heikoksi. Tämä on johtanut sen joutumiseen erittäin uhanalaiseen asemaan, kun erityisesti koirien ja muiden kotieläinten mukana on mantereelta kulkeutunut taudinaiheuttajia.
