FISH HOLT CH. 30 PG. 726-738 Slide 2 CHARACTERISTICS OF FISH ENDOSKELETON Slide 3 CHARACTERISTICS OF FISH ENDOSKELETON GILLS Slide 4 CHARACTERISTICS OF FISH ENDOSKELETON GILLS CLOSED-LOOP CIRCULATORY SYSTEM Slide 5 CHARACTERISTICS OF FISH ENDOSKELETON GILLS CLOSED-LOOP CIRCULATORY SYSTEM KIDNEYS Slide 6 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach Slide 7 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER Slide 8 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Slide 9 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac Slide 10 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac SENSORY ORGANS NOSTRILS-lead to OLFACTORY lobe Slide 11 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton-muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac SENSORY ORGANS NOSTRILS-lead to OLFACTORY lobe EYES-lead to OPTIC lobe Slide 12 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton-muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac SENSORY ORGANS NOSTRILS-lead to OLFACTORY lobe EYES-lead to OPTIC lobe TASTE-tongue, skin Slide 13 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton-muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac SENSORY ORGANS NOSTRILS-lead to OLFACTORY lobe EYES-lead to OPTIC lobe TASTE-tongue, skin EARS-AUDITORY nerve Slide 14 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton-muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly) Swim bladder-regulate vertical position in water-gas sac SENSORY ORGANS NOSTRILS-lead to OLFACTORY lobe EYES-lead to OPTIC lobe TASTE-tongue, skin EARS-AUDITORY nerve LATERAL LINE-senses vibrations in water Slide 15 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) Slide 16 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover Slide 17 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Slide 18 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills) Slide 19 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills) SINGLE LOOP BLOOD CIRCULATION Slide 20 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills) SINGLE LOOP BLOOD CIRCULATION Blood->gills->heart (atrium then ventricle)- >pumped body->gills Slide 21 EXCRETION Most vertebrates conserve water (2/3 of body is water) Slide 22 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Slide 23 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Slide 24 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills Slide 25 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills FRESH water fish have more salt in TISSUES than water-take in salt from environment Slide 26 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills FRESH water fish have more salt in TISSUES than water-take in salt from environment Few fish can live in fresh AND salt water Slide 27 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills FRESH water fish have more salt in TISSUES than water-take in salt from environment Few fish can live in fresh AND salt water KIDNEYS- Slide 28 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills FRESH water fish have more salt in TISSUES than water-take in salt from environment Few fish can live in fresh AND salt water KIDNEYS- Maintain salt and water balance Slide 29 EXCRETION Most vertebrates conserve water (2/3 of body is water) SALT/WATER BALANCE- Sea water 3X salt of fish tissue Excess salt pumped out through gills FRESH water fish have more salt in TISSUES than water-take in salt from environment Few fish can live in fresh AND salt water KIDNEYS- Maintain salt and water balance Removes wastes from blood Excess water leave in form of urine Slide 30 REPRODUCTION Most reproduce sexually and externally *SPAWNING* Slide 31 REPRODUCTION Most reproduce sexually and externally *SPAWNING* Usually spawn in large groups (schools) Slide 32 REPRODUCTION Most reproduce sexually and externally *SPAWNING* Usually spawn in large groups (schools) INTERNAL fertilization in skates, sharks, and rays. Slide 33 REPRODUCTION Most reproduce sexually and externally *SPAWNING* Usually spawn in large groups (schools) INTERNAL fertilization in skates, sharks, and rays. CLASPERS-male organ used to grasp female Slide 34 REPRODUCTION Most reproduce sexually and externally *SPAWNING* Usually spawn in large groups (schools) INTERNAL fertilization in skates, sharks, and rays.
