摘要: Many deep-water coral species have very broad global distributions and are eurybathic from depths of meters to kilometers. Such ecological breadth may be confounded by the presence cryptic species. We currently comparing genetic distances between Paragorgia sp. Primnoa across their distribution depth range in Canada using 18S ribosomal DNA (rDNA) sequences. Initial results show a confusing picture amongst geographically distant taxa. Specimens P. arborea Canadian Atlantic divergent specimen Pacific. The placement Pennatula Anthomastus relative these taxa is also unexpected. expect this topology alter with addition more further testing.
