General Introduction

Fish, like all animals, constantly receive information from their environment through sensory organs. Some sensory organs are easily recognizable as such, others are barely or not at all visible to the naked eye. For example, the large eyes of many fish are striking, indicating to even the layman that many fish have excellent vision. In addition to the sense of sight, the sense of smell and taste of many fish species is also very well developed. Fish, unlike mammals, do not have earlobes or ear openings, yet many fish have excellent hearing. The sense of touch has a great, but often underestimated, importance for us. A gentle touch can comfort or trigger a pleasant tickling sensation, while a firm touch is usually perceived as unpleasant. With the help of the sense of touch, we can recognize a familiar object even in the dark and can—in conjunction with joint receptors and temperature sensors in the fingers—even roughly determine its material properties. Das Kapitel General Introduction benötigt keinen Abstract.
