AUGUST 2005 FINAL REPORT
Bycatch—any species caught in a fishery, but which are not sold or kept for personal use; includes
economic and regulatory discards
Calcareous—containing calcium carbonate
Caldera⎯a type of volcanic crater that is extremely large (over one mile in diameter), usually formed by
the collapse of a volcanic cone or by a violent volcanic explosion
Calf—a young animal dependent on its mother
Callosity—a patch of thickened, keratinized tissue on the head of a right whale, inhabited by large
numbers of whale lice
Calving—the process of giving birth by a whale, dolphin, porpoise, or manatee
Calving interval—the period of time from one birth to the next, generally applicable to cetaceans
Cape—a darker region on the back of many species of dolphins and small whales, generally with a
distinct margin
Carapace—the outer covering of the back of a sea turtle, which is bony for all sea turtle species with the
exception of the leatherback, which has a leathery covering
-2
Carbonate⎯type of rock or sediment formed of carbonate (CO3 ) and another element such as calcium
or magnesium; limestone and dolomite are common carbonate rocks
Carbonate compensation depth⎯depth at which almost all carbonate dissolves, approximately 4,000 to
5,000 m
Carnivore—an animal that feeds exclusively on another animal’s tissue
Catch per unit effort (CPUE)⎯measure of a species relative abundance
Cephalopods—any marine mollusk of the class Cephalopoda, with the mouth and head surrounded by
tentacles (squid, octopus, cuttlefish)
Cetaceans—whales, dolphins, and porpoises
Charter fishing—fishing from a vessel carrying a passenger for hire (as defined in Section 2101[21a] of
Title 45, U.S.C.) who is engaged in recreational fishing
Cheloniidae—the family of hard-shelled sea turtles that includes the green, hawksbill, Kemp’s ridley,
Olive ridley, and loggerhead turtles
Chemosynthesis—the formation of organic compounds from inorganic substances using energy derived
from oxidation
Chevron—a V-shaped stripe
Circumglobal—the distribution pattern displayed by organisms around the world, within a range of
latitudes
Circumtropical—organisms which occur around the tropics of the world (land or sea)
Click—a broad-frequency sound used by toothed whales for echolocation and which may serve a
communicative function; usually with peak energy between 10 kHz and 200 kHz
