easy-to-use iPhone app makes it easy to identify all the fish seen in
shallow water by snorkelers--almost 200 species. Browse for fish by
family group, and then by species. Males, females, and juveniles are
shown for those species in which they differ. Turtles, seals, dolphins,
and whales have been added as a bonus.
Each of the species accounts includes a photo (enlargable to full-screen) and a short paragraph of information.
You can log the fish you see in a "Favorites" list. You can also view a slideshow of the photos, which look bright, crisp, and colorful on the iPhone screen.
app requires an up-to-date iPhone or iPod Touch running OS version 3
