Underwater Spotter® California Ocean Life Guide

Find · Learn · Identify

The Underwater Spotter California Ocean Life Guide highlights the 50 most common and interesting ocean animals found in California waters. Designed for divers and snorkelers, this guide makes fish identification simple, visual, and genuinely fun—no scientific jargon required.

Instead of overwhelming you with hundreds of species, Underwater Spotter focuses on just 50, helping you build confidence and recognition dive by dive.

Unlike Any Other Fish Guide

We wanted a fish identification guide that didn’t feel like homework.

Underwater Spotter Guides are:

• visually clean and easy to use

• packed with fascinating (and sometimes bizarre) fish behavior

• designed for real underwater observation, not memorization

Whether you’re diving, snorkeling, or flipping through between dives, this guide helps you see more by knowing more.

How It Works

🔍 FIND

Challenge yourself to find all 50 ocean animals in the guide.
Each species includes a checkbox so you can track your progress and turn every dive into a purpose-driven search.

🧠 LEARN

Skip the scientific names and focus on what matters.
Each entry highlights:

• fun fish facts

• unique behaviors

• when and where you’re most likely to spot them

The result: better observation and deeper appreciation of marine life.

🐠 IDENTIFY

Learn to recognize entire fish families, not just individual species.

Each family includes:

• 3 obvious visual traits for quick recognition

• 3 simple distinctions to tell commonly confused fish apart

This makes identification faster, easier, and more intuitive underwater.

• Top 50 California ocean animals
