Response to stimuli

In response to light stimuli the millipede Archispirostreptus gigas look for a place to hide because their eyes are very sensitive to light. (Western Exterminator, 2020)However, during the dark it returns to the surface of the earth to feed. It’s responses to predators by curling in as a form of defences into a tight spiral, thereby secreting an irritable liquid from this repugnant glands situated on both sides of body segments.(Archispirostreptus gigas, 2020)

Fuligo septica can exist as cells which are able to move to find food so when they don’t have food in their current location they move to a different location which is a response to the lack of food. A  common habitat for these cells is underneath rotting logs and damp leaves, where the cellulose that the cells use for food is abundant. These cells like environments that are dry and have a lot of light where they then fuse together to form an enormous single cell that contains thousands of nuclei. This form, called a pseudoplasmodium, can ooze about seeking a region of acceptable warmth and brightness. (Slime Molds, 2020)
