Ireland's seashores are famous for their spectacular beauty, ranging from exposed rocky headlands that receive the full power of the Atlantic to enclosed sea loughs and sheltered mudflats. Its northern latitude means that some Arctic species find a home there, but the warm currents that flow up from the Gulf of Mexico also make Irish shores habitable for species found in southern Europe, the Canaries, and the Mediterranean. Providing habitats like no other, Ireland's coasts are teeming with plant and animal life. Whether you visit on a sunny summer day or for a wild walk in winter, there is always something interesting to see, either living on the shore or washed up from the sea. Beginning with clear background information on types of shore, tides, waves, coastal habitats and conservation, this highly accessible guide has everything you need to understand the wildlife on the coastline. A helpful identification guide uses simple questions (e.g. 'Does it have a shell?') to guide you to the correct section (e.g. 'Snails, mussels and their relatives'), where you will find an introduction to the species, followed by detailed entries on the most common shoreline inhabitants: Irish and Latin names, size, distribution, and memorable nuggets of information (did you know banded wedge shells can leap if disturbed?). Written by qualified marine biologists with a passion for their subject, this is the ideal companion on any seashore ramble, whether you are a beginner or an experienced naturalist.
