Abstract: The present invention provides a multiple oriented two piece terrarium enclosure system which utilizes a base member for engagement with a shell structure having a slanted frontal viewing surface for improved viewing capabilities. The present invention also provides unique lateral access to the interior of the terrarium. Specifically, the shell structure has a cutout portion for providing a fully enclosed system when the shell structure is positioned in a first orientation, and alternatively providing a means for accessing the interior of the terrarium when the shell structure is positioned in a second orientation. This dual orientation capability allows improved access for feeding and cleaning the terrarium with minimal disturbance to the habitat or its inhabitants. The shell structure utilizes a securing mechanism for maintaining positioning of the shell structure with respect to the base while in either a first orientation or a second orientation.
