Salmon • Tuna • Shark • Seahorse • Clownfish Examples:
Generally cold-blooded: Affected by environment • Exceptions: Tuna and Mackeral sharks are warm-blooded • Maintain body temperature with countercurrent circulation Body Temperature Control
Scales • Camouflage • Spines • Poison Covering/Means of Defense
Different sensory organs detect movement • Teeth based on diet • Flat • Sharp Teeth/Special organs on Head Sensory Organs
Mouth • Esophagus • Stomach • Pyloric Caeca • Intestines Digestive System
Gills • Countercurrent Exchange Respiration
2-chamber heart • Closed Circulatory system • Single-loop Heart and Loops
External • Female lays eggs • Male releases sperm over eggs Fertilization
Oviparous – All of the embryonic development occurs within the eggs • External birth Type of Birth
Fins • Swim bladder maintains buoyancy • Contracting muscles on either side of backbone Movement, Muscles, Appendages
Some are bioluminescent • Some can reflect colors • Some can “fly” • Some eat more than humans Special Features
Some travel in schools • Some escape predators by confusing them • Avoid collisions with neighbors • Homing behavior • Reproductive behavior Innate Behavior
Adapt to environmental change • Fast response to feeding • Modify foraging behavior Learned Behavior
Traveling in schools • Mating tactics Cooperative Behavior
How are fish similar to other life? • Dependent on oxygen • Utilizes circulatory system to transport oxygen throughout the body • Consumes other organisms for survival • Synthesizes proteins for survival • How are fish different from other life? • Use gills as a means of filtration to gather oxygen • Utilize swim bladder to adjust depth in water. Evolution
Special Adaptations for Gathering Resources • Sensory organs on frontal lobes to detect movement. • Smooth bodies and fins to move quickly in water • Energy conservation/utilization • Nitrogenous waste is in the form of ammonia. Fish do not have to process it before it is excreted • Some fish are cold blooded, allowing them to use their environment to regulate their body temperature rather than using the body to regulate the temperature Energy
Some travel in schools • Some escape predators by confusing them • Avoid collisions with neighbors • Homing behavior • Reproductive behavior • Adapt to environmental change • Fast response to feeding • Modify foraging behavior Storing and Responding to Information
How do fish interact with the environment? • Symbiotic relationship with environment and other organisms • What is the fish’s role in the ecosystem? • It provides food source for predators • Keeps prey population in check Interactions
