	My mom says I can get some but I don't know which one to get! Does anyone have any experience with them?

	Like a Venus Fly Trap? :P My friend has one, I haven't seen it in the flesh yet (well, I don't really want to :|) but I've seen videos of him feeding it and teasing it. -_-

	Yeah, a Venus Fly Trap is definitely something I'm considering. I really, really want one!! Well, not one. Haha.

	Never mind! After doing a ton of research I realized that winter is not a good season to get a Venus Flytrap- I'll get one in the spring. During the winter they hibernate. That means you put them in a plastic bag in the fridge. Sucks. I'm thinking about getting some African violets though!

	This one is not carnivorous but I'd just like to share this info with you. The sensitive plant (Mimosa pudica) is a pantropical weedy herb in the legume family (Fabaceae). The pinnately compound leaves are composed of numerous tiny leaflets. When touched, the leaflets begin to fold up very rapidly and the leaf stalk (petiole) suddenly bends downward. [Sleep movements also occur in the sensitive plant and in many other species of leguminous trees and shrubs in which the leaflets slowly fold up at night.] These plant movements in response to a stimulus (called nastic movements) are associated with loss of tugor pressure in the leaves. The sensitive plant is especially interesting because of the rapidity of the wilting process, an entire leaf suddenly drooping after it has been touched. As one leaflet folds up, the stimulus moves to other parts of the leaf until all the leaflets and adjacent leaves have folded up. Two distinct mechanisms, one electrical and the other chemical, appear to be involved in the rapid spread of the stimulus in sensitive plants. At the bases of the leaflets are jointlike thickenings called pulvini, with a large pulvinus at the base of each petiole. When a leaf is stimulated by touch, heat or wind, there is a chain reaction in which potassium ions migrate from one side of each pulvinus to the other side. This is followed by a rapid shuttling of water molecules from parenchyma cells in one half of the pulvinus to cells in the other half. This action results in loss of turgor pressure that causes folding of the leaflets and eventually the entire leaf. The entire process may take only a few seconds. When the leaflets fold up and instantaneously become wilted, it is often difficult to see where the leaf was in its original turgid state. It has been suggested that this rapid wilting process may be an adaptation to grazing mammals or ravenous insects.
