About the Marine Flatworms Guide

The Marine Flatworms guide focuses on polyclad flatworms commonly encountered by divers across tropical Indo-Pacific reefs.

These delicate animals display extraordinary colours and patterns, making them popular subjects for underwater macro photography.

Unlike laboratory or aquarium references, this guide shows flatworms as divers actually encounter them underwater, allowing easier recognition during dives or when reviewing underwater photographs.

The guide is useful for:

  • scuba divers
  • underwater macro photographers
  • marine life enthusiasts
  • dive professionals
  • citizen science observers
