Fish Anatomy & Taxonomy
Dorsal Fin Large fin on back that varies in size, shape and position Stabilizes fish
Pectoral & Pelvic Fin Pectoral Fins: Located on side of body – Used for steering & locomotion Pelvic Fins: Located on belly or under pectoral fins – Function in stabilizing & braking
Anal & Adipose Fin Anal Fin: Located on ventral side (underside) behind the pelvic fins Adipose Fin: Small fin located between the dorsal and caudal fin
Caudal Fin Caudal Fin: Tail fin that varies in shape, affecting the fish’s speed and buoyancy Used for propulsion
Mouth Mouth: The size and shape of a fish’s mouth indicates what they feed upon
Barbels Barbels: “Whiskers” near the mouth Used by bottom feeding fish to sense food
Some Hints Body more than 5x as long as broad Hinge of mouth Scales

INTRODUCTION TO FISHES PART 3 Fisheries. Swim Bladder Fish are more dense than water. Swim Bladders provide buoyancy to offset the weight. Only in bony.

FISH CHARACTERISTICS 5 th Grade. How do FINS work? Pectoral Fins –used to maneuver the fish up, down, and sideways -> turning especially Pelvic Fins.
External Anatomy of Fish. The Head Mouth Shape/ Position Superior Mouth –Also known as an undershot or upturned mouth –Eats food above the fish –May.

Introduction to Fish. What makes a fish a fish? Jaws/ Mouths Terminal: Opens at midline Terminal: Opens at midline Superior: Opens towards top of midline.
Fishes Kingdom-Animalia Phylum- Chordate (Notocord- at some point can turn into a backbone) Class- Jawless Cartilage Bony.
Dogfish because they turn their head side to side when they swim Spiny because they have spines near their fins.
Are you Shark Smart? Shark Anatomy. Shark Skeleton Made of calcified cartilage Spinal Nerve Cord- carries nerve impulses Vertebrae- form the sharks backbone.

FISH. Phylum Chordata All chordates have for all or part of their lives: A. A notochord - Flexible rod shaped support B. A hollow dorsal nerve cord -
External Parts Nares (nostrils) – used to detect orders and are very sensitive Mouth - where they take in food and water to breathe, may or may not.

Chordates and Vertebrates. Chordates The notochord is an elongate, rod- like, skeletal structure dorsal to the gut tube and ventral to the nerve cord.
Fish. Classification Kingdom- Animalia Phylum- Chordata Sub Phylum- Vertebrata Classes- Agnatha, Chondrichthyes, Osteichthyes.
Fish locomotion T he source of propulsion for virtually all fish comes from: 1.Undulation of the body 2.Paired Fins: Pectoral Pelvic 3.Unpaired Fins:
