The imagery on this page is supplemental to a paper entitled Five new species of the damselfish genus Chromis (Perciformes: Labroidei: Pomacentridae) from deep coral reefs in the tropical western Pacific, by R.L. Pyle, J.L. Earle and B.D. Greene (2008, Zootaxa 1671:3-31). The abstract is as follows:
Five new species of the damselfish genus Chromis (Perciformes: Labroidei: Pomacentridae) are described from specimens collected from deep (>60 m) coral-reef habitat in the western Pacific by divers using mixed-gas closed-circuit rebreather gear. Two of the five new species (C. abyssus and C. circumaurea) are each described from specimens taken at a single locality within the Caroline Islands (Palau and Yap, respectively); one (C. degruyi) is described from specimens
collected or observed throughout the Caroline Islands, and two (C. brevirostris and C. earina) are described from specimens collected from several localities throughout the Caroline Islands, Fiji, and Vanuatu. All five species can easily be distinguished from other known Chromis, and from each other, on the basis of color and morphology. These new species represent the first five scientific names prospectively registered in the official ICZN ZooBank registry. Moreover, the electronic online edition of this document has been specially formatted with many embedded links to additional resources available online via the internet to enhance access to taxonomically-relevant information, and as a demonstration of the utility of international standards for biodiversity informatics.
About the Species
This specimen, the holotype, was collected slightly north of Blue Holes caverns off Ngemelis Island, Belau (Palau) Islands, Micronesia by R.L. Pyle on 27 April 2007. It was made available to the University of Texas High-Resolution X-ray CT Facility for scanning by Dr. Richard Pyle of the Bishop Museum. Funding for scanning was provided by Dr. Pyle. Funding for image processing was provided by a National Science Foundation Digital Libraries Initiative grant to Dr. Timothy Rowe of The University of Texas at Austin.
About this Specimen
The specimen was scanned by Matthew Colbert on 17 December 2007 along the coronal axis for a total of 810 slices. Each slice is 0.1356 mm thick, with an interslice spacing of 0.1356 mm and a field of reconstruction of 63 mm.
