An identification guide for the shore-fish fauna of the Tropical Eastern Pacific. This App is the first of a set of 2 portable identification guides for Apple touch-screen devices that will cover the shore-fish faunas of the tropical American marine regions on both sides of the central American Isthmus: the Tropical Eastern Pacific, the Greater Caribbean (Caribbean and adjacent areas).

This App was adapted from the 2008 website Shorefishes of the tropical eastern Pacific: online information system (, which in turn was derived from a 2002 CD system, that was developed from English (1994) and Spanish (1998) book editions.

This stand-alone App works independently of the internet.

• Complete English and Spanish interfaces. Connect to the Spanish interface by setting Spanish in the language preference of your device.

• Covers 1,358 species; includes over 5,000 images to help identify them. Users can select to work with either the entire fauna, or with the Diver Group, a subset of 686 species that could be found within SCUBA diving depths on or adjacent to reefs in different parts of the region.

• A page for each species includes a detailed description (with information on its form, color, size, habitat and depth range), 1 or more species images (primarily photographs), key-features that distinguish it from similar species, a link to a page displaying similar species, and a map of its regional range.

• Browse among alphabetic lists of species and species-within-families, changing name-sorting between scientific and common (first or last) names.

• A search engine uses any combination of generic common names, location, habitat, and fish features (shape, color pattern and colors) to identify fishes.

• A glossary of scientific terms is linked to each species page.

• Keys that use a series of “either/or” choices of features that allow identification of members of two species-rich families.

• The notebook module allows (1) review of recently visited species pages and (2) construction of lists that record observations about fishes. New lists can be assembled from scratch or by making blank copies of existing lists. Lists are organized in folders, and are downloadable by email.

• The iPad version includes glossary images, and high resolution range maps with dots indicating site records.

• New for this version: option to work with either the entire fauna or a diver subgroup; 63 more species and almost 40% more images; habitat added to the fish ID search engine.

Take all the fish you love everywhere!

This app is genius. You can sort by fish you are likely to see diving and location. Super helpful for fish ID off the grid!

I Can't Believe It's Free!

I've paid $30 or more for similar electronic or print Fish ID references! This is a great reference. Love that you can store notes to document which species you've seen. Can't wait till guides for the other regions are released.
