Fish and Fishing Flashcards
Vertebral Column
Fish spine.
Neural crest
A group of ectodermal cells that develop into a variety of tissues, including spinal and autonomic ganglia, connective tissue around the brain and spinal cord, and parts of the facial bones.
Fin
To help it move, swim, and balance.
Scale
Protective scales outside the fish that protect it.
Operculum
A bony plate that covers and protects the gills of most bony fishes.
Atrium
A chamber of the heart that receives blood from the veins and forces it by muscular contraction into a ventricle.
Ventricle
A chamber of the heart that receives blood from one or more atria and pumps it by muscular contraction into the arteries.
Nephron
one of the functional units of the kidney that filters the blood, selectively reabsorbs substances and excretes nitrogenous waste, excess water, and salts in the form of urine.
Lateral line
A system of sense organs found in aquatic vertebrates, used to detect movement, vibration, and pressure gradients in the surrounding water.
Spawning
Release or deposit eggs.
Swim bladder
A gas-filled sac present in the body of many bony fishes, used to maintain and control buoyancy.
Jawless fish
Agnatha is a superclass of jawless fish in the phylum Chordata, subphylum Vertebrata, consisting of both present and extinct species.
Cartilaginous fish
Cartilaginous fish are fish that have a skeleton made of cartilage, rather than bone.
Bony fish
Osteichthyes, popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue, as opposed to cartilage.
Bowfin/Dogfish
