Examples of mixed-species groups include wildebeests forming groups with zebras, [3] and different species of birds that form large foraging flocks. [4] Group living may sometimes be confused with collective animal behavior. Collective animal behavior is the study of how the interactions between individuals of a group give rise to group level ...

The Eurasian badger (Meles meles) is an example of a species that incur a cost of group living on the successful reproductive rates. Females present in larger groups of badgers have an increased reproductive failure rate compared to solitary badgers. This is a result of increased reproductive competition within the female individuals in the group.
It was thought that the sharks form a polyphyletic group: some sharks are more closely related to rays than they are to some other sharks, [21] but current molecular studies support monophyly of both groups of sharks and batoids. [22] [23] The clade Selachimorpha is divided into the superorders Galea (or Galeomorphii), and Squalea (or ...

[58] [59] [60] In a few species such as peacocks and black grouse, leks are composed of brothers and half-brothers. The lower-ranking males gain some fitness benefit by passing their genes on through ...
