Cover of Fish ID for Divers
I teach diving for a living and I still cannot name plenty of what I photograph. Underwater identification is difficult for real reasons, and nobody warns new divers about them. This is what actually helps.

What Is Inside

  1. Why fish ID is hard, and why that is not your fault
  2. Shoot for identification, not for the shot
  3. The features that actually decide an ID
  4. Start with the family, not the species
  5. The lookalike traps that catch everyone
