Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Humpback whales yakawanikwawo ichigadzira mamwe manzwi ekutaurirana akadai se "grunts", "groans", "thwops", "snorts" uye "barks". Hove zhinji dzebalene dzinogadzira manzwi anenge 15<unk>20 hertz. Zvisinei, boka revaongorori vezvinhu zvipenyu zvomugungwa, rinotungamirirwa naMary Ann Daher weWoods Hole Oceanographic Institution, rakashuma muNew Scientist muna December 2004 kuti vakanga vave vachitevera whale muNorth Pacific kwemakore 12 iyo yakanga "ichiimba" pa52 Hz. Masayendisiti haakwanisi kutsanangura musiyano wakakura uyu; asi anotenda kuti whale iyi inonzi baleen uye haisi mhando itsva, zvichiratidza kuti marudzi anozivikanwa iye zvino angava nenzwi rakawanda kupfuura zvaifungidzirwa kare. Pane kusawirirana munzanga yesayenzi pamusoro pokusiyana kwemashoko emhove iyi uye kana iri nhengo yemhove yemasanganiswa yakadai semanyoro akanyorwa zvakanaka eBlue Whale neFine Whale. Muna 2009, vatsvakurudzi vakawana kuti rwiyo rwemhove yebhuruu rwave ruchikura mumutinhimira waro kubva kuma1960. Nepo kusvibiswa neruzha kwawedzera ruzha rwomugungwa nemadhesiberi anopfuura 12 kubvira pakati pezana remakore rechi20, mutsvakurudzi Mark McDonald akaratidza kuti manzwi akakwirira aizotarisirwa kudai hove dzacho dzaitamburira kunzwiwa. Hove dzinouraya dzakacherechedzwa kuti dzigoburitsa runhare rurefu rurefu rwakajairika uye rwakawanda rwekufamba kure kubva pa10<unk>16 km (6.2<unk>9.9 mi) pamwe chete nenzwi pfupi rinogona kufamba kure kubva pa5<unk>9 km (3.1<unk>5.6 mi). Kufona kwepedyo kunotaurwa munguva dzokushamwaridzana uye dzokuzorora nepo kufona kwenguva refu kuchiwanzoshumwa panguva dzokutsvaka zvokudya uye dzokudya. Chinokosha zvikurusa iBeluga ("canary yomugungwa") iyo inobudisa nhevedzano huru kwazvo yemaridza muridzo, kurira nokurova.  Mubvunzo: Ndeipi iri rimwe zita rehove inonzi beluga?
