Whales, seals, oysters, crabs, nudibranchs and seaweeds are just a smattering of the sea life you'll find in this comprehensive, easy-to-use pocket guide from Rick Harbo, the dean of popular Pacific Northwest marine biology.

Pacific Reef & Shore is the 21st century successor to Harbo's 1980 bestseller Tidepool and Reef, with more species, up-to-date scientific information and many brilliant new full-colour photographs of the 300 most common plants and animals of the intertidal zone. Arranged for quick identification with colour-coded sections, this ingenious guide has written descriptions of each organism, with size, habitat and interesting facts conveniently placed next to its photo.

Authoritative and accessible, Pacific Reef & Shore is the indispensable companion for divers, kayakers and beach strollers alike.
