| Summary: | "Oar Feet and Opal Teeth is an extended introduction to the form and biology of the small (at most a few millimeters) crustaceans known as copepods, as a group Copepoda. Brief biographical sketches of more than 20 practicing copepodologists emphasize their commitment to understanding these keystone aquatic organisms better. The focus is on the free-living forms in oceans and lakes, shaped like rice grains with feet. Forms and functions of their limbs are described, as well as the heart, brain, eyes, siliceous teeth, gut, and gonads. Variations are treated in food capture, mate-finding, reproduction, and development of embryos, larvae (nauplii), and juveniles (copepodites). Adaptations including high-speed escape jumps, transparency, several modes of bioluminescence, and diel vertical migrations to remain in the dark around the clock help copepods to avoid becoming predator gut contents. Emphasis is given to egg and larval modes of diapause and to chromatin diminution, a means shared with nematodes of dumping junk DNA. Species concepts and taxonomic practices for copepods are explained. Molecular genetics and high precision morphologic comparisons are marshaled to relate the distinct copepod orders and families as an evolutionary tree (a phylogeny) with its root in the Cambrian era"--Publisher's description. |
