🐋Gray whale

Eschrichtius robustus (Lilljeborg, 1861)

Harmaavalas (Eschrichtius robustus) on valaiden lahkoon kuuluva laji. Harmaavalaiden heimoon Eschrichtiidae kuuluu vain yksi suku Eschrichtius ja siihen yksi valaslaji, harmaavalas. Harmaavalaat vaeltavat vuosittain pitkiä matkoja päästäkseen lisääntymisalueilleen. Kaksi harmaavalsta on ollut SeaWorld San diegossa 1900 luvun loppupuolella.
