Fish & Fishing Flashcards
Approximately 33 bones called a Vertebrae, divided into 5 regions.
Vertebral column
Transient embryonic structure in vertebrates that gives rise to most of the peripheral nervous system and several non-neural cell types, like smooth muscle cells of the cardiovascular system, pigment cells in the skin, craniofacial bones, cartilage, and connective tissue.
Neural crest
Flat appendage on many aquatic vertebrates and invertebrates used for propelling, steering and balance
Fin
Each of the small, thin horny or bony plates protecting the skin of fish and reptiles, typically overlapping one another.
Scale
the hard bony flap covering the gill slits in fishes
Operculum
each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein.
Atrium
any of various hollow organs or parts in an animal body
Ventricle
each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine.
Nephron
a visible line along the side of a fish consisting of a series of sense organs that detect pressure and vibration.
Lateral line
release or deposit eggs.
spawning
a gas-filled sac present in the body of many bony fishes, used to maintain and control buoyancy.
Swim bladder
vertebrates without jaws
Jawless fish
distinguished by having a skeleton of cartilage rather than bone, including the sharks, rays, and chimeras.
Cartilaginous fish
distinguished by a skeleton of bone, and comprising the majority of modern fishes.
Bony fish
long wavy dorsal fin, eyespot near tail, Green with whitish belly.
Bowfin/Dogfish
