Beskrivelse af Sea Squirts and Sponges of Britain and Ireland
Sea squirts and sponges are found in most seafloor habitats around the coasts of Britain and Ireland. Despite being the dominant life forms in many areas, these two groups of under-recorded marine animals are often confused with one another, and most divers and snorkellers can recognise and name very few species. In fact, around 500 species of Ascidiacea (sea squirts) and Porifera (sponges) have been described so far in British and Irish seas, corresponding to over 4% of the worldΓÇÖs total.
This book is recommended reading for anyone who wants to identify and discover more about these fascinating and diverse animals. Rather than relying on the characteristics of preserved specimens, this guide uses marine photography and detailed underwater observations to concentrate on in situ features, allowing you to record species without collecting them. Most sea squirts found in Britain and IrelandΓÇÖs shallow waters are included, together with the most easily recognised sponges. Whether you are a student, a diver, a rockpooler or simply an enthusiast, this is an essential companion.
ΓùÅ Over 115 species described in detail with in situ photographs
to help with underwater recognition
ΓùÅ Information on size, depth, habitat and distribution
ΓùÅ Key distinguishing features and areas of confusion in identification highlighted
ΓùÅ Details of body structure, life histories, digestive and reproductive processes
ΓùÅ Information about predators, interactions between species,
non-native and problem invasive species
