A guided tour of shells and marine invertebrates, with a catalog of cards you can open whenever you need them. Short lessons, local progress, and review: you'll learn to recognize shapes, families, and habitats without getting lost in cold lists.
From the catalog, you can move on to the cards, save what you want to review, and use the exercises to consolidate the names. A glossary and search engine keep terms organized as you progress through the course.
For those who love the shore and want an organized reading experience, not a chaotic collection of photos.
