The fish pulls water into its mouth.

Oxygenated water passes over the gills.

Gills take Oxygen from water and release carbon dioxide.

Water then passes out of fish through gill slits.

3. Bony

Fish have a closed circulatory system.

A two chamber heart pumps blood in one loop.

Blood goes from the heart to the gills, from the gills to the rest of the body where the oxygen is used, and then from the body back to the heart.

3. Bony

Fins provide fish with a larger surface area with which to push against water. This helps with speed and efficiency.

B. Types of Fish

3. Bony

External fertilization, spawning,is method used by most fish. Female lays eggs in water. Male spreads a cloud of sperm over the eggs.

Internal fertilization occurs in few species. Eggs are fertilized and develop inside the female. The female gives birth when the young are mature enough to live independently.

B. Types of Fish

1. Jawless

2. Cartilaginous

3. Bony

Central nervous system, consisting of the brain and spinal cord, is the primary integrating mechanism.

Peripheral nervous system, consisting of nerves that connect the brain and spinal cord to various body organs, carries sensory information from special receptor organs such as the eyes, internal ears, nares (sense of smell), taste glands, from environment to the brain

B. Types of Fish

1. Jawless

2. Cartilaginous

3. Bony

No jaws or scales

Mouths contain radula-like structures for scraping , stabbing and sucking living or decaying tissues

Ex. Lampreys

Parasites that attach themselves to other fish and feed off of them

Ex. Hagfish

Scavengers that feed on dead fish

B. Types of Fish

1. Jawless

2. Cartilaginous

3. Bony

Jaws, scales and skeletons made of cartilage

Usually carnivores

Ex.Sharks

Poor eyesight, great ability to smell

Can’t pump water over gills, so need to be moving or in current

Ex. Skates and Rays

Spend most time partially buried in sand

Gill stills on ventral side

B. Types of Fish

1. Jawless

2. Cartilaginous

3. Bony

Skin covered with denticles

Five to seven gill slits per side

No swim bladder

Internal fertilization

Five to seven gill arches

loosely attached lower jaws

5. Nervous System

B. Types of Fish

1. Jawless

2. Cartilaginous

3. Bony

Jaws, scales, skeleton made of bone, swim bladder

Swim bladder helps fish stay in varying depths of water with minimal energy use.

95% of all fish fit into this category

Ex. Trout, goldfish, walleye, perch, tuna
