Marine Biology Chapter 10 || Questions and 100% Accurate
Answers.
alevins correct answers Newly hatched salmon that still have a yolk sac attached. They are
known as fry after they lose the yolk sac and begin feeding.
ammocoetes correct answers The burrowing freshwater larvae of lampreys.
ampullae of Lorenzini (am-POOL-ee of lohren-ZEE-nee) correct answers Organs in sharks and
other cartilaginous fishes that can detect electrical signals in the water.
anadromous (uh-NAD-ruh-muhs) correct answers A term applied to fishes that reproduce in
freshwater and spend their adult lives in the marine environment.
anal fin correct answers The ventral, unpaired fin of fish that lies behind the anus.
aposematic coloration correct answers Bright and conspicuous coloration exhibited by animals
that are distasteful or dangerous to their attackers. Such colors are presumed to warn away
attackers. Also known as warning coloration.
atrium correct answers One of the chambers of the vertebrate heart; it collects blood from the
body and acts as a primer pump.
barbel (BAHR-behl) correct answers A fleshy projection on the head of some fishes that usually
fulfills a sensory role. Barbels typically contain taste buds.
bearers correct answers Fish that carry their offspring with them, either internally or externally.
benthic spawners correct answers Fish that lay eggs that attach to some type of surface. There is
no parental care after spawning and the larvae may become pelagic or remain benthic.
brood hiders correct answers Fish that hide their eggs but show no parental care after spawning.
bump-and-bite attack correct answers Shark attack mode in which the victim is bumped before
being bitten.
catadromous (kuh-TAD-ruh-muhs) correct answers A term applied to fishes that reproduce in the
marine environment and spend their adult lives in freshwater.
caudal fin (KAW-duhl) correct answers The tail fin of a fish.
chloride cells correct answers Specialized cells located on marine fish gills that remove excess
electrolytes from the body.
, chromatophore (kroh-MAT-uh-fohr) correct answers A special cell in an animal's skin that
contains pigment molecules.
claspers correct answers Modified pelvic fins of male cartilaginous fishes that transfer sperm to
the genital opening of a female.
cloaca correct answers A common chamber and outlet for the digestive, urinary, and
reproductive systems of certain animal species.
countercurrent multiplier system correct answers A biological mechanism involving fluids, with
a concentration gradient between them, flowing in opposite directions in parallel channels. This
arrangement maintains a stable gradient that allows maximum exchange of heat or dissolved
substances between the two fluids.
craniates correct answers Members of the phylum Chordata that possess a cartilaginous or bony
skull (cranium).
cryptic coloration correct answers Color patterns that camouflage animals, allowing them to
blend with their environment to avoid predators or ambush prey.
ctenoid scales (TEE-noyd) correct answers Thin, overlapping scales on advanced bony fishes.
Their exposed posterior edges have small spines.
cycloid scales (SY-kloyd) correct answers Thin, overlapping scales with a smooth posterior edge
that are found in less-advanced bony fishes.
dental plates correct answers Feeding apparatus of hagfish consisting of plates containing curved
rows of sharp, horny cusps. The plates are hinged along the midline, opening and closing like a
book.
dorsal fin correct answers A fin on the dorsal surface of a fish.
elasmobranch correct answers Group of cartilaginous fishes (class Chondrichthyes) containing
the sharks, rays, and skates.
elver correct answers A juvenile eel (Anguilliformes).
fusiform body shape correct answers Spindle-shaped body of many fishes and other animals,
characterized by a rounded middle portion and tapering toward each end.
ganoid scales (GAN-oyd) correct answers Thick, bony scales that do not overlap. Ganoid scales
are found in some less-advanced bony fishes.
gas gland correct answers A gland that secretes gas into the swim bladder of fishes or into the
float of some large pelagic cnidarians.
