Chordata Class Agnatha ( Jawless Fish) Class Chondrichthyes
(Cartilaginous Fish) Class Osteichthyes ( Bony Fish)
- Slide 3
- Fish first appeared in the Earths oceans 540 MILLION years ago.
Fishes are WATER - dwelling vertebrates Characteristics: SCALES
FINS THROATS WITH GILL SLITS
- Slide 4
- SOLUTION TO POLLUTION IS DILUTION POINT SOURCE pollution that
you can point at, it comes from a specific source. NON-POINT SOURCE
pollution you can not point at; comes from run-off
- Slide 5
- Name that source
- Slide 6
- JAWLES FISH Class Agnatha 1.) These fish are the most
PRIMITATIVE of all fishes (THEY ARE THE OLDEST !) 2.) NO JAWS,
SCALES, and PAIRED FINS. 3.) The entire skeleton is made of
CARTILAGE. Meaning these fish do not have any BONES.
- Slide 7
- JAWLESS FISH Class Agnatha 4.) The main form of support these
fish have is from the NOTOCHORD. 5.) Examples: LAMPREY and
HAGFISH
- Slide 8
- JAWLESS FISH Class Agnatha 6.) LAMPREY has a suction-cup mouth,
which is surrounded by sharp teeth. This mouth will attach to a
fish and scrapes away at the fishs skin. The lamprey then sucks up
the TISSUES of its victim!
- Slide 9
- LAMPREY DRAW MY MOUTH IN YOUR NOTES!
- Slide 10
- JAWLESS FISH class Agnatha 7.) The hagfish uses four to six
short TENTACLES that sound its nostrils and mouth as its sensory
organ for TOUCH. 8.) The hagfish feeds on DEAD or dying fishes by
TEARING out pieces of the fish with its tongue and teeth-like
structures.

- HAGFISH

- CARTILAGENOUS FISH Class Chondrichthyes 1.) Cartilaginous
fishes mainly include SHARKS, RAYS, and SKATES. 2.) Sharks have a
skeleton made of CARTILAGE with toothlike SCALES covering their
bodies (makes their skin feel like sandpaper). 3.) The body of a
shark includes: a. TORPEDO-SHAPED BODY b. CURVED TAIL c. ROUNDED
SNOUT WITH MOUTH UNDERNEATH

- TIGER SHARK https://www.youtube.com/watch?v=3-Zk1nd_dY8 Fish
are friends, not food.
- Slide 14
- GREAT WHITE SHARK

What would happen if we got rid of sharks?
- Slide 15
- CARTILAGENOUS FISH class Chondrichthyes 4.) Sharks have 3,000
very long teeth arranged in many rows inside its mouth. 5.) Sharks
that eat MOLLUSCS and CRUSTACEANS have FLATTENED teeth that help
them CRUSH the shells of their prey. 6.) The bodies of skates and
rays are FLAT.
- Slide 16
- BULLNOSED RAY
- Slide 17
- CARTILAGENOUS FISH class Chondrichthyes 7.) Skates and rays
have two LARGE, BROAD fins that stick out from their sides. They
beat these fins to MOVE through the water. 8.) Rays and skates
often lie on the ocean FLOOR where they HIDE by using their fins to
cover their bodies with sand. 9.) Some rays have a poisonous SPINE
at the end of their long, thin tail, which is mainly used for
DEFENSE rather than for catching PREY.
- Slide 18
- BONY FISH Class Osteichthyes 1.) These fish have a skeleton
made up of HARD BONE. 2.) There are two main categories of bony
fishes: a.) LOBE- FINNED bony fishes b.) RAY- FINNED bony
fishes

- Slide 29
- ATLANTIC SALMON
- Slide 30
- Class Osteichthyes 3.) Ray-finned bony fishes include PERCHES
and SEA HORSES. 4.) COELACANTHS are the only living species of
lobe-finned bony fishes.
- Slide 31
- Class Osteichthyes 5.) Bony fishes have an SWIM BLADDER. This
gas-filled sac gives bony fishes BUOYANCY or the ability to FLOAT
in water. By inflating or deflating its swim bladder, a fish can
float at DIFFERENT levels in the water.
- Slide 32
- So why do fish belly up when they die?
- Slide 33
- Class Chondrichthyes 6.) Tuna travel in large numbers called
SCHOOLS.

- 1.) Circulatory System: CLOSED circulatory system, where BLOOD
is contained within blood vessels. GILLS will provide the oxygen
Chamber of the heart that receives blood from the body: ATRIA
Chamber of the heart that pumps blood to the body: VENTRICLE
- Slide 36
- Slide 37
- 2.) EXCRETORY SYSTEM Tube-like KIDNEYS that filter nitrogen-
containing WASTES from the blood. Most fishes get rid of the
nitrogen-containing wastes in the form of AMMONIA. This
accumulation of ammonia is why you must always check the water
quality of your aquariums!
- Slide 38
- AQUARIUM NITROGEN CYCLE
- Slide 39
- 3.) SENSORY DETECTION Since fishes do not hear sounds very
well, fish can detect faint CURRENTS and VIBRATIONS in the water
through a DISTANT - TOUCH system. Many fishes have a great sense of
smell and taste. A shark can detect the presence of one drop of
BLOOD in 115 liters of seawater.
- Slide 40
- FISH REPRODUCTION EXTERNAL FERTILIZATION The female lays EGGS
in water, and the MALE will cover the eggs in sperm to allow for
fertilization OUTSIDE of the body. Examples: SALMON

- Slide 41
- FISH REPRODUCTION INTERNAL FERTILIZATION Fertilization will
take place in the females body and the female will lay a FERTILIZED
egg. Examples: SHARKS
