7. Coloration in Fish
Chromatophores – Surface pigment cells that expand and contract to produce various colors.
Camouflage
Disguise

Countershading – Silver or White ventral sides and dark gray or blue-gray dorsal sides.
Why ????

8. Locomotion
Myomere- Bands of muscle along the sides of fish used for locomotion.
Lateral line- A visible line running along the length of a fish body. It detects vibrations that allow fish to swim together in a school.

9. Reproduction
Migration is the regular movement of an organism from one location to another.
Examples??
A few fish have a migratory pattern opposite that of the salmon. They will spend a majority of their lives in rivers, migrating to the ocean to reproduce this is known as a catadromous behavior. (They migrate from fresh water to the ocean to reproduce.)

10. Hermaphroditism
A situation in which an animal has the reproductive organs of both sexes.
See page 152.

11. Reproduction
Internal Fertilization: is a result of direct transfer of sperm from the male to the female. This occurs among sharks and other cartilaginous fish. The male has claspers located next to the anal fins used for directly depositing sperm into the female.

12. External fertilization. Most marine fish reproduce in this way
External fertilization. Most marine fish reproduce in this way. Fish spawn or release their gametes into the water, after a period of swimming in courtship patterns.
Thousands of eggs are released in some cases millions. When the eggs meet the sperm in the water, fertilization takes place and the embryo begins to develop in the fertilized egg.
By producing many fertilized eggs, the chances of at lease some of the eggs hatching and then some of the resulting larvae surviving into adulthood are greatly increased.

13. Oviparous – A type of development in which eggs are hatched outside a female’s body.
Viviparous – A type of development in which the young obtain their nutrients directly from the mother and are birthed live.

14. On Your Own Questions
6.14 A person puts five male fish into his aquarium and is surprised to find eggs developing a few weeks later. What happened?
6.15 A fish specimen is found to have 10 unfertilized eggs in her reproductive tract. What type of development does this species probably have?

16. Gills Gills are in the pharynx, Toward the mouth. As they
Open and close their mouth
Water is pushed past the gills.
The gills of fish are located
On bony or cartilaginous
structures called gill arches.
Each have a double row of bladelike gill filaments. Each gill filament has a large supply of capillaries in order to allow for gas exchange. There is a rich supply of blood-filled capillaries, the gills have a bright red color. To increase the surface area for O2 transfer, each filament has feather-like separations called lamellae.
