The Australian zebra finch (Taeniopygia castanotis)[2] is the most common estrildid finch of Central Australia. It ranges over most of the continent, avoiding only the cool humid south and some areas of the tropical far north. The bird has been introduced to Puerto Rico and Portugal.[1] Due to the ease of keeping and breeding the zebra finch in captivity, it has become Australia's most widely studied bird; by 2010, it was the most studied captive model passerine species worldwide, by a considerable margin.[3]

Vitta zebra, commonly known as the zebra nerite, is a species of sea snail, a marine gastropod mollusk in the family Neritidae.[

Color patterns vary, with only dark or colored shells or no stripes. They are typically found attached to objects, surfaces, or each other by threads underneath the shells. Although similar in appearance to the quagga mussel, the two species can be easily distinguished. When placed on a surface zebra mussels are stable on their flattened underside while quagga mussels, lacking a flat underside, will fall over.

Die Harnischwelse (Loricariidae) sind eine in Mittel- und Südamerika vorkommende Familie  der Ordnung der Welsartigen.
