Introduction

One of the most striking features of the shore is the rich diversity of plant and animal life to be found there. A wide range of invertebrates, some highly mobile, others fixed or sedentary, and shore fishes, are a characteristic feature. Brightly coloured lichens often form distinct bands on the high shore; seaweeds may be present in abundance, and on mud flats flowering plants may dominate. Physical factors change rapidly and it is on the shore that the student has the opportunity to observe and study some of the most fascinating adaptations shown by plants and animals.
