Seabook is an Android app that provides a comprehensive guide to marine life. It is an essential tool for scuba divers, freedivers, snorkelers, and aquarium enthusiasts who want to learn more about the marine life they encounter. With over 1,500 species of fish, sharks, rays, nudibranchs, mollusks, crustaceans, echinoderms, and more, Seabook makes it easy to identify any marine creature you come across.

The app offers three categories - Fish, Creatures, and Corals, Sponges, Plants - with a total of 275 groups and subgroups. Each group has a detailed description, distribution, habitat, lifestyle, legal status, maximum size and depth, and more. Seabook also provides filters to search by color, pattern, location, body shape, social behavior, tail fin shape, and other criteria. Additionally, the Direct Search feature allows users to find a specific species by scientific or common name.

Seabook is a great solution for diving safaris as it offers an offline mode, allowing users to access the app even in remote diving sites without an internet connection. It is an excellent alternative to traditional heavy guidebooks, and everything you need is already in your smartphone.
