Welcome

The aim of this atlas is to to provide a consistent approach to the identification of megafaunal morphotypes that have been imaged as part of environmental assessments of various areas across the CCFZ.

The CCFZ

The Clipperton-Clarion Fracture Zone lies to the west of North America continental margin in the Pacific Ocean. The zones is approximately 4500 miles in length with an average depth of between 4000 and 4800 m. Exploration of the abyssal region of the Clipperton–Clarion Fracture Zone (CCFZ) reveals that there is a considerable biodiversity at many scales. Most of this biodiversity remains undescribed. The reasons for this are many but relate fundamentally to the great size of the region, difficulty in sampling at great depths far from land and a discrepancy between the rate of discovery of new species and the availability of taxonomic expertise to describe them (the so called taxonomic impediment).

Taxonomy of megafauna morphotypes

What are megafauna?

Animals visible in sea bottom photographs and often captured in trawls.
