They are able to change in green and brown patterns in only a matter of minutes. Unlike other amphibians and reptiles they do not change colour according to their background colour, instead it is due to temperature and moisture levels, yet it still provides them with a very successful method of camouflage, allowing them to be overlooked by potential predators, Hill The Chilean four-eyed frog Pleurodema thaul has developed another form of disguise, rather than hiding itself it attempts to warn off predators by pretending it is a much larger organism, and therefore perhaps a potential threat to anything wishing to prey upon it. Other features Shubin said evolved are the abilities of sight, smelling, and hearing. Just like today, we use different opsins to see in color than we do in black in white.

Respiration is not just the mechanical process of breathing — the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction. It is also the metabolic process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP energy. In a typical scenario, organisms find greater difficulty obtaining oxygen O 2 than dealing with the waste gas product of respiration — carbon dioxide CO 2. This is because CO 2 is more readily dissolved in plasma and so can be excreted faster than oxygen is obtained. This comparative article will look at the way different species all tackle the problem of obtaining oxygen for aerobic respiration, starting with insects, then amphibians, fish, mammals and finally birds.
