Ichthyopedia

The most in-depth field guide to California's marine species. It contains every species you'll meet on a Southern California dive, with the rest of the coast in progress. Click a card for nearly every piece of information you could want to know about the species: regulations, seasonality, edibility, the spearfishing brief, and more.

About rarity: each species' rarity is based on how abundant it is at diveable depths and how hard it is to spot. Rarity to a diver can be very different from rarity to a fisherman.
