Fish are super profitable vertebrates. as a result of a protracted and divergent historical past they're now present in virtually each conceiv­ capable aquatic habitat. This radiation has been observed via nice variety in constitution, body structure, and behavior. regardless of this variability, fish needs to remedy a couple of simple difficulties which are universal to all animals. an important of those are: (1) to discover and ingest applicable foodstuff; (2) to prevent predation; and (3) to breed. the most goal of this publication is to explain the range of behavioural options that fish use in dealing with those difficulties. My strategy has been to attract jointly fabric from either box and laboratory paintings that's extensively scattered within the litera­ ture. the foremost emphasis is on box stories, for the reason that my major problem is with adaptive suggestions to difficulties, and that i think those are probably to be safely perceived through staff who're acquainted with the common ecological environment in their animals. after all, many information of behaviour can't be visible and quantified accurately within the box, and as a result i have never neglected laboratory reviews. notwithstanding, even the following i've got concen­ trated on paintings that illustrates the diversity of options that fish use to unravel the 3 uncomplicated difficulties. a lot very important paintings, for example on causation, improvement, and studying, isn't included.
