In the attached images we see mooses attached to a variety of trees in some of the mountain cloud rain forests of Panama. Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple, one-cell thick leaves, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Mosses are now classified on their own as the division Bryophyta. There are approximately 12,000 species.
