Wake-up Explain the difference between a vertebrate and invertebrate. What are some characteristics of fish? What are the three groups of fish?

Phylum Chordata Vertebrates: Fish Christopherson

Characteristics of Fish

Fish External Anatomy Dorsal Fin Caudal Fin Scale Nostril Mouth Anus Operculum Anal Fin Pectoral Fin Pelvic Fin

Integument Scales

Protect from attacks by predators, parasites, and other injuries Scales Function Protect from attacks by predators, parasites, and other injuries

Scales are permanent on fish Scales are permanent on fish. They can be used to determine the age of fish. Annulus = Year

Endoskeleton: Internal skeleton made up of bone Skeletal Endoskeleton: Internal skeleton made up of bone

Internal “skeleton”: Cartilage

Respiration Gills Watch video Fish open their mouth to take in a gulp of water containing dissolved oxygen. The water moves over the gills and out through the operculum.

Closed system: Have a two-chambered heart Circulatory System Closed system: Have a two-chambered heart

One-way: Food comes in through the mouth and out through the anus Digestive One-way: Food comes in through the mouth and out through the anus

External fertilization: Female lays eggs and males fertilize (outside) Reproductive External fertilization: Female lays eggs and males fertilize (outside)

Diversity: Jawless Fish

Characteristics of Jawless Fish Jaws are absent

Characteristics of Jawless Fish Paired fins are generally absent

Characteristics of Jawless Fish In most cases, the skeleton is cartilage

Can live in fresh or salt water. Example: Lampreys Can live in fresh or salt water.

Example: Lampreys Some are parasitic

Lamprey Video #1 Lamprey Video #2

Lives in the ocean typically underground in burrows. Example: Hagfish Lives in the ocean typically underground in burrows.

Example: Hagfish Lacks paired fins, eyes, and scales Surrounding the mouth is a ring of tentacles.

Hagfish produce a slime for defense (video)

Diversity: Cartilaginous Fish

Endoskeleton is entirely cartilage Characteristics Endoskeleton is entirely cartilage

Example: Sharks Watch Video

Example: Skates and Rays Watch Video

Diversity: Bony Fish

Characteristics of Bony Fish Endoskeleton is bone

Largest group of vertebrates; The total number of bony fish exceed that of all other vertebrates combined. I just picked a few to feature. Flounder Video
