What effect does ambient temperature have on the cardiovascular system? Solifugae: An order of arachnids that includes a diverse group of spider-like animals that tends to inhabit arid lands around the world. In some unicellular eukaryotic organisms such as the amoeba, shown inFigure 1, cellular wastes and excess water are excreted by exocytosis, when the contractile vacuoles merge with the cell membrane and expel wastes into the environment. Insects and Amphibians: Insects and amphibians are two classes of animals. It also means they can migrate easily, as is the case with many butterfly species. Birds are characterized by their coats of feathers, their warm-blooded metabolisms, their memorable songs (at least in certain species), and their ability to adapt to a wide range of habitatswitness the ostriches of the Australian plains and the penguins of the Antarctic coastline. o E.g.

Animals that host these are known as chelicerates. These can lead to new traits, such as altered coloration, new susceptibility to disease or protection from it, or different shaped features (such as legs, antennae, toes or internal organs). In social insects, as in humans, different individuals do different jobs.
