  1. Practice Quiz Fish

  2. Class Agnatha Hagfish Hagfish feed on dead or dying fishes

  3. Class Agnatha Lamprey Lampreys attach to other fishes and suck their blood. Note the oral disc with horny teeth that can act as a rasp to cut a hole in the fish they attach themselves to.

  4. 1. Mouth 4. Cloaca 2. Liver 5. Opening of cloaca 3. Spiral Valve 6. Rectal gland Chondrichthyes What is the function of #6? Salt secretion

  5. Cycloid Ctenoid Placoid scales Sharks have placoid scales

  6. What is the function of this sensory system? The drawing shows the lateral line system of a shark. Boney fishes also have a lateral line system. The lateral line system allows the animal to detect shock waves in water just like your eardrum responds to shock waves in air. This allows the animal to detect movement in the water column such a swimmer kicking in the water .

  7. 1. Pectoral fin 5. Caudal fin 6. Posterior dorsal fin 2. Pelvic fin 7. Anterior dorsal fin 3. Lateral line 8. Operculum 4. Anal fin

  8. Common name? Ratfish Kingdom? Phylum? Subphylum? Class? Animalia Chordata Vertebrata Chondrichthyes

  9. This shark has a heterocercal tail. 7. Caudal fin (Heterocercal tai) 1. Rostrum 2. Mouth (Sharks have a ventral mouth) 8. Posterior dorsal fin 3. External gill slits 9. Anterior dorsal fin 4. Pectoral fin (Notice it is large and “wing-like”.) 10. Lateral line 5. Pelvic fin 11. Spiracle (a modified gill slit) 6. Clasper (The presence of a clasper makes this shark a male)

  10. 1. Gill Arch 2. Gill Raker

  11. The holes are openings of sensory structures called Amullae of Lorenzini. These sensory structures allow the shark to detect minute electrical currents.

  12. 1. Gill Arch 3. Gill Arches 2. Gill Raker

  13. Swim bladder Heterocercal Homocercal

  14. This fish is a whale shark. It is the largest living fish. How does this animal feed? Whale sharks are filter feeders that feed on plankton.

  15. Animalia Chordata Osteichthyes Parrot fish

  16. 1. Stomach 2. Pyloric caeca 3. Intestine 4. Esophagus 5. Stomach 6. Intestine 7. Pyloric caeca

  17. 1. Heart 2. Vein 3. Capillary bed (the site of gas exchange) This is where oxygen leaves the blood and enters the tissues 4. Artery
