 I’ve discovered the perfect present for young and old. Because nearly every New Zealander visits a seashore at some time, The New Zealand Seashore Guide offers them an ideal introduction to everything that lives at the beach. And not only the beach but also the nearby estuaries, lagoons, mudflats, rockpools and sandhills.

The text is bang up-to-date with modern research but is written in a friendly and easily understood way. The arrangement is logical, user-friendly and well-designed. As a bonus it’s an enjoyable read.

Sally Carson has the ability to put words together so skilfully that they reach out from the page and drag the reader in. Who can resist a section beginning, ‘For many coastal birds, the seashore is like a restaurant with limited opening hours.’? 

Many of her sentences create remarkable, often unforgettable, mental images. Of the Common octopus (Wheke) she writes, ‘As long as an opening is big enough to fit their beak, they will be able to squeeze their body through.’

This book also passes the curious items test, where facts are so unexpected and surprising that people feel obliged to read them out aloud. Did you know that ‘New Zealand is famous the world over as a place to study living brachiopods’? That’s because elsewhere they have been extinct for up to 260 million years. Once you have read up on Brachiopods you’ll also know that there are 38 species of this shellfish (lamp shells) tucked away in our rocky shores. They come in two colours (red and black) and they haven’t changed much in the last 550 million years. Sumptuous colour photos show just why washed-up shells are called mermaids’ toenails.

Amazing! We’re five paragraphs into a review of a Potton and Burton book and this is the first mention of the illustrations! They are, of course, superb. Even by the already high standards of Rod Morris’s photography, they are magnificent. Every picture, whether underwater or above, is sharp, clear and – given the subject matter – surprisingly colourful. The Shortsnout pipefish displays its red gill cover, while the  Red striped anemone, Orange clingfish and Olive rockfish show just why they got their names. The Jingle shell (Poro) is ‘a beautiful golden yellow, orange or silver colour’ so Rod Morris has shown it three times, the third as a beachcomber’s jingling wind-chime.

The cover picture, an atmospheric shot of Motukiekie Beach’s rock pools at low tide with starfish tightly draped over the rocks, looks like an alien planet. Even more alien are some of the creatures photographed including the various sea squirts, the nudibranchs and the chitons.

The Sacoglassan sea slug, a sap-sucker with club-like outgrowths, is straight out of Dr Who, as is the Ten tentacle worm.

The various coastal images come from all over New Zealand but Otago Peninsula’s beloved Harbour Cone, which has become an icon in Rob Morris’s work, appears satisfyingly often.  Nearby Portobello is the home of the ‘Fish Hatcheries’ better known as the NZ Marine Studies Centre, Department of Marine Science of the University of Otago, where Sally Carson is the director.

Her book invites young would-be scientists to try unusual seashore experiments. ‘Whelks … are well known for their predatory lifestyle and keen sense of smell’ is a sentence we might not agree with. Is it really well-known? But then we are told exactly how to carry out our own smell and speed tests on whelks.  ‘Being curious and making observations are key skills that contribute towards being a good scientist.’

The Seven-armed sea star (Papatangaroa) is known to consume at least 60 prey species, ranging from snails to paua. To aid in this task it has pedicellaria, little pincers. Sally Carson’s enthusiasm for sea creatures bubbles up in her suggestion: ‘If you put the hairy part of your arm near the upper surface of this sea star, you may feel its tiny pincers grabbing these fine hairs.’ This book is certain to spawn a generation of young naturalists (most with smooth arms).

Sections on every subject from Sponge Secrets to Beachcombing are truly illuminating. The one-page essay on Mussel Anchor Lines begins with describing the byssal threads extruded by mussels to use as climbing ropes and anchors. Then Sally Carson speculates on how these threads offer potential for man-made medical adhesives and stretchy sutures. Oh, and more acidic conditions in the sea are weakening these threads and thus pose a possible threat to mussel communities and the aquaculture industry.

Essays about A Changing Ocean and Other Coastal Concerns offer up-to-date research on the degradation of our seas and seashores.  

For foodies, the Edible Seaweed section includes serving suggestions for seaweed salad and kelp chips. Speaking of kelp, there are reminders of bags to carry shellfish being fashioned from the blades of kelp. I had thought we also carved kelp stalks to make bouncy balls for beach cricket but I see now that we were carving the stipes.

All the terms used are clearly defined, often with carefully-labelled photographs (such as Tidal Zonation) to assist. Common names, Maori names and scientific names for species are given along with the description, habitat, lifestyle, size, tidal zone and distribution. For critters that live regionally rather than nationally, there are even maps which show their distribution.  

The New Zealand Seashore Guide comes in a handsome easy-to-hold format, with a sewn binding that allows the book to opened flat without damage.  It has literally been designed to take to the beach, where it will be the ideal companion.
