Welcome to the future of coral identification.
Introducing Hexacorralia by Christina, the first-of-its-kind photographic taxonomy guide capturing the stunning biodiversity of corals through the lens of macro photography. This is not just a reference tool. It is a work of art, a scientific archive, and a must-have collector’s piece for anyone who loves, studies, or works with coral reefs.
With over 650 meticulously photographed coral specimens, Hexacorralia offers a visual experience unlike anything available in marine biology, reefkeeping, or aquaculture today. Designed for marine scientists, coral collectors, aquarium enthusiasts, conservationists, reef photographers, and STEM educators, this project brings the microscopic beauty of coral into breathtaking focus.
Hexacorralia is a multi-volume visual taxonomy guide documenting the diversity of corals from across the reef-keeping and scientific community. Created by Christina Rene Duncan, a professional underwater macro photographer and marine science advocate, the project captures the minute morphological details that differentiate coral species and color variants.
This collection includes species from across the Actiniaria, Alcyonacea, Corallimorpharia, Scleractinia, and Zoantharia orders, arranged in visually clean, taxonomically accurate groupings. Each coral is labeled by genus or species (where applicable) and organized by family. From the textured, otherworldly beauty of Discosoma and Ricordea mushrooms, to the architectural complexity of Acropora, Favia, and Micromussa, to the psychedelic explosion of Zoanthids — this collection spans the full color, form, and taxonomic spectrum of reef life.
In a world where coral reefs are disappearing at an alarming rate, the documentation of living biodiversity has never been more urgent. While scientific journals may catalog coral species by Latin names and skeletal structures, they rarely show what hobbyists and researchers actually see — the living, breathing coral in full color.
Hexacorralia fills this critical gap, acting as a bridge between science and art, between professional researchers and home aquarists. It provides a tool that’s both visually intuitive and scientifically grounded, making it easier than ever to:
Identify coral species and variants with confidence
Educate students, clients, or customers in reef biology
Verify morph differences across lighting and flow conditions
Catalog personal collections or commercial frag tanks
Appreciate the artistic beauty of coral up close
This is not a theoretical guide — it is a visual archive of living organisms, captured with precision and purpose.
Each purchase of Hexacorralia by Christina includes:
Multiple Poster-Size Coral Charts featuring 650+ photographed specimens
Volume Organization by Coral Order and Family (Vol. 1: Actiniaria, Alcyonacea, Corallimorpharia, Vol. 2: Scleractinia, Vol. 3: Zoantharia)
Taxonomically Accurate Groupings with names and visible identifiers
Ultra-High Resolution printing for clarity in fine coral features
Museum-Quality Glossy Finish – stunning enough to display in labs, offices, classrooms, or retail spaces
Whether framed on your wall or used as a daily reference, Hexacorralia is both educational and visually striking.
Hexacorralia by Christina was designed with a wide range of coral lovers in mind:
Take your reefkeeping to the next level. Instantly identify coral types in your tank, verify incoming frags, and track lineage across collections.
Add value and trust to your business with a professional-grade ID tool. Use it to train staff, educate customers, or decorate your retail space.
A quick-reference visual companion to skeletal taxonomy. Excellent for educational fieldwork, outreach events, or classroom instruction.
Highlight the diversity at risk. Use this guide as part of conservation campaigns, presentations, or citizen science education.
Make coral science fun and visual. Hexacorralia is ideal for teaching high school and college students about biodiversity, taxonomy, marine ecosystems, and evolution.
Appreciate coral as art. This guide doubles as a curated photographic collection, showcasing the symmetry, color, and beauty of coral macro imagery.
Christina Rene Duncan is a renowned underwater macro photographer and marine science communicator. With decades of experience in saltwater aquatics, conservation, and education, Christina is known for her ability to combine scientific accuracy with visual storytelling. She has photographed thousands of coral specimens under studio conditions, using advanced macro lenses and lighting setups to capture details that are often invisible to the naked eye.
The Hexacorralia project represents years of meticulous documentation, categorization, and post-production — all driven by a singular mission: to preserve and celebrate the living legacy of reef-building corals for future generations.

This foundational volume explores three vibrant coral orders. Actiniaria (sea anemones), Alcyonacea (soft corals), and Corallimorpharia (mushroom corals) are beautifully captured, highlighting their textures, movement, and fluorescent pigmentation. A perfect starting point for understanding the softer side of reef ecosystems.
This volume is a deep dive into hard corals, the backbone of reef structures. You’ll find stunning photos of Acropora, Favia, Echinophyllia, Micromussa, Leptastrea, Favites, and many more.
A full poster dedicated to Zoanthids — the wildly popular soft coral group known for their endless color morphs. Over 270+ zoas & palys are cataloged in this volume alone, each one photographed to highlight its unique color palette and polyp structure.
Quantities will be limited for the first print run of Hexacorralia by Christina. Don’t miss your chance to own this collectible coral guide that will set the new standard for visual coral identification.
