Cama (animal) are herbivores that eat shrubs and other plant matter. As they can drink large amounts of water at a time, camas can survive with little or no water for long periods. The camelid family consists of the Old World camelids (the dromedary camels, Bactrian camels, and wild Bactrian camels) and the New World camelids (the llama, vicuna, suri alpaca, huacaya alpaca, and guanaco). Though there have been successful and fertile hybrids within both major groups of camelids, the cama marks the first instance of cross-breeding. The following is a table comparing some of the characteristics of camelids. Cama (animal) A
Alternatives to animal testing Alternatives to animal testing Alternatives to animal testing are the development and implementation of test methods that avoid the use of live animals. There is widespread agreement that a reduction in the number of animals used and the refinement of testing to reduce suffering should be important goals for the industries involved. Two major alternatives to "in vivo" animal testing are "in vitro" cell culture techniques and "in silico" computer simulation. However, some claim they are not true alternatives because simulations use data from prior animal experiments and cell cultures often require animal derived products, such as serum or cells.
