Walen geh\u00e9ieren zu de gr\u00e9isste a bemierkensw\u00e4ertste D\u00e9ieren op der \u00c4erd. D\u00ebs m\u00eberesd\u00e9ieren liewen an de Weltmier, vun de waarmen tropesche Gew\u00e4sser bis zu de kale Mierer ronder\u00ebm d'Pole.<\/p>\n
Obwuel Walen hiert Liewen am Waasser verbr\u00e9ngen, atmen si Loft duerch Blasl\u00e4cher, d\u00e9i op hirem Kapp uewen sinn. Si mussen reegelm\u00e9isseg op d'Uewerfl\u00e4ch zr\u00e9ckkommen, fir ze atmen, ier si nees no Iessen sichen oder duerch den Ozean reesen.<\/p>\n
Walen si waarmbluttig, gebueren lieweg Jungd\u00e9ieren a stillen hir K\u00e4lber mat M\u00ebllech. Eng d\u00e9ck Fettlag, genannt Blubber, h\u00eblleft hinnen, sech g\u00e9int kal Waasser ze sch\u00fctzen, an sp\u00e4ichert Energie w\u00e4hrend laanger Migratiounen.<\/p>\n
Walen ginn allgemeng an Bartenwalen an Z\u00e4nnwalen opgedeelt. Bartenwalen filteren kleng D\u00e9ieren aus dem Waasser mat flexiblen Placken an hirem Mond. D\u00ebs Grupp enth\u00e4lt Blauwalen, Buckelwalen a Grauwalen.<\/p>\n
Z\u00e4nnwale benotzen hir Z\u00e4nn, fir F\u00ebsch, Tintenf\u00ebsch an aner Beute ze f\u00e4nken. Vill vun hinnen benotzen och Echolokalisatioun, produz\u00e9ieren Tounen a lauschteren no de zr\u00e9ckkommende Echos, fir hir \u00cbmwelt ze verstoen. Pottwale, Belugas a Orcas geh\u00e9ieren zu d\u00ebser Grupp.<\/p>\n
De blo Wal ass dat gr\u00e9isst je bekannt D\u00e9ier, dat je gelieft huet. E ausgewuessene Wal kann m\u00e9i laang w\u00e9i e Stadsbus ginn a w\u00e4it iwwer honnert Tonnen schw\u00e9ier sinn. Trotz senger enormer Gr\u00e9isst ern\u00e4hrt en sech haapts\u00e4chlech vun klengen Krebst\u00e9ieren, d\u00e9i Krill genannt ginn.<\/p>\n
Walen kommuniz\u00e9ieren mat Klicken, Pfeifen, Pulsen a komplexe Lidder. E puer Kl\u00e4ng k\u00ebnnen \u00ebnner Waasser iwwer grouss Distanzen reesen. Buckelwalen si besonnesch bekannt fir hir laang, musterhaft Lidder.<\/p>\n
Vill Aarte migr\u00e9ieren all Joer dausende vu Kilometer. Si f\u00ebdden sech dacks an kale, n\u00e4hrstoffr\u00e4iche Gew\u00e4sser, ier si an m\u00e9i waarm Regiounen reesen, wou si sech paaren a Kanner kr\u00e9ien.<\/p>\n
Kommerziell Juegd huet eemol zu schw\u00e9iere R\u00e9ckg\u00e4ng an ville Walpopulatiounen gefouert. Haut stinn d'Walen och virun Geforen w\u00e9i Fangger\u00e4ter, Sch\u00ebffkollisiounen, \u00cbnnerwaassergeraascht, Verschmotzung an \u00c4nnerungen an den Ozeansystemer.<\/p>\n
Konservatiounsprogrammer, m\u00e9i s\u00e9cher F\u00ebschereipraktiken, gesch\u00fctzt Liewensraim an international Zesummenaarbecht k\u00ebnnen h\u00ebllefen, d'Walpopulatiounen er\u00ebm opzebauen. D'Waleschutz \u00ebnnerst\u00ebtzt och m\u00e9i gesond Ozeaner, well d\u00ebs D\u00e9ieren eng wichteg Roll an de marine Iwwerliefensnetzer an de N\u00e4hrstoffzyklen spillen.<\/p>","protected":false},"excerpt":{"rendered":"
