Das aquatische Leben unter unseren Ozeanen, Seen, Flüssen und Bächen ist erstaunlich! Vom mikroskopisch kleinen Zooplankton bis zum größten Tier der Erde, dem Blauwal, gibt es Unterwasserleben in allen möglichen Formen und Größen. Da 71% der Erde mit Wasser bedeckt sind, ist es kein Wunder, dass wir von dem, was unter der Oberfläche liegt, so fasziniert sind. Tatsächlich schätzen Wissenschaftler, dass es fast 1 Million verschiedene Arten von Wassertieren gibt. Süßwasser-Ökosysteme beherbergen hauptsächlich Fische, wirbellose Tiere und Reptilien, während der Ozean ein breites Spektrum an Meereslebewesen beherbergt, darunter Fische, Muscheln, Krebstiere, Reptilien, Haie und Meeressäuger wie Wale, Delfine, Robben und Seekühe.
