2.  Allows movement through the water without much resistance  Helps minimize energy necessary for motion  Most fish have a long, streamlined shape

3.  Fish want to remain undetected by other fish  Serves two purposes  Undetected by predators  Undetected by prey, easier to feed  Reflects the habitat in which a species lives  Top usually dark, bottom usually light colored to help be undetected

4.  3 purposes: stability, positioning, locomotion  Fins on the back: dorsal fins  Fins on the stomach: pelvic and anal fins  Without fish not able to stay upright  Pectoral fins (stick out on sides) help fish ‘aim’ itself in the water

5.  Tail fin: caudal fin  Push the fish to provide locomotion  Fins are thin membrane supported by a network of rays and spines  Spines are hard and sharp; pointed ends; some fish  Rays are soft; branch out at the end; most fish

6.  Draw the dorsal, pelvic, pectoral and anal fins

7. Dorsal Pectoral Pelvic Anal Caudal

8. SENSEDESRIPTION WELL- DEVELOPED POORLY DEVELOPED Sight Eyes: Many can see above, below, ahead & behind them Smaller eyes in turbid waters In many speciesIn turbid water Smell Nostrils: Provides entry for odors All fish: extremely well (especially those with poor sight) Hearing Ears: Lacking. Sound travels through skin to inner ear Most fish cannot pinpoint sounds Taste Taste buds: Inside and outside their mouths X Vibration Sensation Lateral Line: Runs from head toward tail (canal of cells sensitive to low frequency vibrations) Important for detecting predators or prey, avoiding obstacles and maintaining position

10.  Scrappy fighters  North American  ‘Warm water’ fish  Prefer nutrient-rich shallows around lakes and backwaters of rivers  Most are spring spawners and are nest builders  Males guard fertilized eggs

20.  Both Black and White (black = 7-8 dorsal spines, white = 6 dorsal spines.)  Mottled Markings  Color is not a good identification indicator  Very thin, perhaps the thinnest of all sunfish  8-10 inches is common

22.  Brown eye  Brown coloration, with light vertical stripes along the sides

23.  Schooling predators  Abundant across most of the northern U.S.  Cool lakes and streams  Considered finest eating of freshwater game fish  Spawning occurs in spring  Fertilized eggs left unguarded over sand, gravel or rocks

25.  Canines along the lower jaw  irregularly-shaped vertical blotches along sides  Upper half of body has mottled vertical stripes  Dark blotch on back of anterior dorsal fin, no spots on dorsal fin  Silvery, opaque marble eyes that glow in the dark  White tip on lower edge of caudal fin

27.  Very similar to a walleye  spots on the anterior dorsal fin, no black blotch at the back of anterior dorsal  no white tip on low caudal fin

29.  Golden Yellow Coloration on their sides. (may vary)  6-8 dark vertical bands along their sides  have two dorsal fins, membrane between the two is black  caudal fin is slightly rounded and forked  3.5 times as long as deep  unlike walleyes, they do not have canines

30.  Support freshwater and saltwater recreational and commercial fisheries  Cold water fish  Average weight: <1 lb to more than 40lbs  Have delicate, rich, oily pink to red flesh  Fast streams, deep lakes

32.  Has an elongated and compressed body  squared-tail  wormlike markings on back and head  red spots along the side of their bodies with blue halos.  Lower fins have a white leading edge, followed by a black border

34.  “X” shaped markings on back and upper half of their body  squared tail  numerous small spots on the head  inside of the mouth is white  10-12 anal rays

36.  Many small spots on the body  Distinctive pink horizontal stripe down each side of the body  squared tail with spots  10-12 anal rays

38.  Silvery color with irregular wormlike markings on back and dorsal fin  Light spots in body and tail  deeply forked tail with spots on edge leading to the body  10-11 rays in their anal fin  inside of mouth is white

40.  Some black spots on upper half of body  grey-black mouth, with teeth set in black gums  squared tail with spots on both halves  15-19 anal rays

42.  Small black spots on backs, sides above the lateral line, base of dorsal fin, and upper half of caudal fin.  Inside of mouth is grey or black, with teeth set in white gums  Slightly forked tail  12-15 anal rays

43.  Found in almost every type of habitat  Some grow quite large (100+lbs)  Spines- can puncture and cause sharp bee-sting pain  Have whiskers  Bottom Dwellers

45.  Scaleless, tough skin  8 barbels  Three sharp spines, (1 dorsal, 2 pectoral)  Black spots on lower side of body  Deeply forked caudal fin
