    \n
  1. Alder:<\/strong>\u00a0Selv om man ikke vet n\u00f8yaktig hvor gamle hvalene kan bli, vet man at de kan leve i mer enn 100 \u00e5r. I 2007 ble det funnet en harpunspiss - patentert i 1879 - i ryggen p\u00e5 en hvithval. Hvalens alder ble ansl\u00e5tt til 211 \u00e5r, men den kan teoretisk sett v\u00e6re mellom 177 og 245 \u00e5r gammel.<\/li>\n
  2. Vennskap:<\/strong>\u00a0Kn\u00f8lhvalhunner danner vennskap med andre hunner og kommer sammen hvert \u00e5r. Det betyr at de husker vennene sine og er i stand til \u00e5 finne hverandre blant andre hvaler i de store verdenshavene.<\/li>\n
  3. Menneskelige stemmer:<\/strong>\u00a0Hvithvaler har en evne til \u00e5 etterligne menneskestemmer. I ett tilfelle var en hvithval i fangenskap (kalt Lugosi) i stand til \u00e5 si sitt eget navn. I et annet tilfelle ble en hvithval (kalt NOC) s\u00e5 flink til \u00e5 etterligne menneskestemmer at forskerne trodde de overh\u00f8rte en samtale mellom to mennesker. Den samme hvalen fikk ogs\u00e5 en dykker i tanken til \u00e5 sv\u00f8mme opp til overflaten fordi han trodde at noen ropte navnet hans n\u00e5r hvalen \"snakket\".<\/li>\n
  4. Pattedyr:<\/strong>\u00a0Hvaler er pattedyr, noe som blant annet inneb\u00e6rer at de m\u00e5 opp til overflaten for \u00e5 puste luft (i motsetning til fisk<\/a>som kan puste under vann ved hjelp av gjellene).<\/li>\n
  5. Hvalen beordrer:<\/strong>\u00a0Hvaler er en orden som er delt inn i 3 underordener: bardehvaler (14 arter), tannhvaler (70 n\u00e5levende arter) og grindhvaler (utd\u00f8dd).<\/li>\n
  6. Bardehvaler:<\/strong>\u00a0I stedet for tenner har bardehvaler bardeplater som de bruker til \u00e5 filtrere maten fra vannet. Bardehvaler har ogs\u00e5 to bl\u00e5sehull, mens tannhvaler bare har ett. Eksempler p\u00e5 bardehvaler er: bl\u00e5hval, gr\u00f8nlandshval, kn\u00f8lhval, finnhval, nordkaper og gr\u00e5hval.<\/li>\n
  7. Tannhvaler:<\/strong>\u00a0Tannhvaler har mange sm\u00e5, spisse tenner i munnen som de bruker til \u00e5 holde fast byttet. Tannhvaler lever hovedsakelig av fisk, blekksprut og sel. Eksempler p\u00e5 tannhvaler er: spermhvaler, delfiner<\/a>Flaskehalsdelfiner, flaskehalsdelfiner, spekkhoggere, hvithvaler, narhvaler og niser.<\/li>\n
  8. St\u00f8rste dyr:<\/strong>\u00a0Bl\u00e5hvalen er det st\u00f8rste dyret som noen gang har eksistert p\u00e5 jorden. En bl\u00e5hval kan bli 33 meter lang og veie opptil 200 tonn. En bl\u00e5hval har plass til 100 mennesker i munnen, og hjertet er p\u00e5 st\u00f8rrelse med en liten bil. Blod\u00e5rene er s\u00e5 store at en basketball kan flyte gjennom dem.<\/li>\n
  9. Moby Dick:<\/strong>\u00a0Boken \"Moby Dick\" er basert p\u00e5 en sann historie. Den virkelige hvalen het Mocha Dick og angrep et engelsk hvalfangstskip rundt 1820. Skipets besetning endte opp p\u00e5 en \u00f8de \u00f8y der de ble drevet til kannibalisme. Mocha Dick var en albinohval dekket av rur (sm\u00e5 krepsdyr som fester seg til hvalene) og ble vanligvis observert med harpuner og torv i huden etter hvalfangernes mislykkede angrep.<\/li>\n
  10. Adopsjon:<\/strong>\u00a0Hvaler kan adoptere andre dyr og til og med gjenstander. I 2011 observerte forskere en spermhval som adopterte en delfin som var f\u00f8dt med deformert ryggrad og hadde blitt utst\u00f8tt av sin egen delfinflokk. P\u00e5 samme m\u00e5te har man sett gr\u00f8nlandshvaler adoptere gjenstander som treplanker, skjeletter og lignende som de tar med seg og behandler som sine egne barn.<\/li>\n<\/ol>\n

    Fakta: Hvalenes n\u00e6rmeste n\u00e5levende slektninger er pardannede hovdyr (klovdyr) som hjort og flodhest.<\/strong><\/em><\/p>\n

    Hadde det ikke v\u00e6rt for den lille \"zombieormen\", eller \"snuteormen\" som den ogs\u00e5 kalles, ville det v\u00e6rt mange hvalbein p\u00e5 havbunnen. Zombieormens latinske navn er Osedax mucofloris, som bokstavelig talt betyr \"beinspisende sn\u00f8rrblomst\". Ormen spiser hvalbein ved \u00e5 dekke dem med slim og etablere et slags rotsystem i beina. Ormen har ingen munn, s\u00e5 huden produserer syre som bryter ned knoklene. Ormen lever av protein og kollagen fra knoklene, men har verken ford\u00f8yelsessystem eller endetarm, noe som gj\u00f8r den enda mer oppsiktsvekkende.<\/strong><\/em><\/p>","protected":false},"excerpt":{"rendered":"
