Document Summary

Invertebrates: colonial invertebrates live in aggregations for mutual benefit, example: the portuguese man-of-war is composed of four different types of polyps with different specializations such as feeding or defense. Social interactions: any interaction between two or more animals, this can mean positive or negative interactions, examples: mating, communication, wolf leaving mark on tree and another wolf coming by and smelling it. Group living advantages: protection from predators, example musk oxen circle around offspring to defend from predators and fish schooling together to defend from predators. Types of information: public information- access to a cue. Information cascade- a(cid:272)(cid:272)ess to a(cid:374)other"s de(cid:272)isio(cid:374: example, rapid escape behavior, public information: another individual takes flight quickly to protective cover, you look up and see same cue and escape as well. Information cascade: another individual takes flight and so you do the same based on their behavior: foraging, public information: another individual returns with a food item.
