Slide5Physical characteristics Gills Backbone Paired fins Single loop circulation
Two chamber heart
Size males reach just
15m
and females reach only about
9m
there are larger sizes as well.
bony fish have two types of fins lobe finned and ray finned.
Slide6How they reproduce?Sperm and egg developed in separate male and female individuals.Males and females may look similar or they made look very different.Bony fish are hermaphrodites which means a single individual can produce both sperm and egg
Slide7Behavior Many species spend most of their time lying on the ocean bottom.They swim continually.Some bony fish species are most active at dawn and dusk.
Slide8HABITATBony fishes are found in every type of aquatic environment. lakes RiversTropical rivers and polar oceans
Slide9Bony Fish Anatomy There are two types of bony fish: ray finned and lobe finned.1-Ray finned:Most present day fish.
2-Lobe finned fish
Ancestors of amphibians
Slide10Slide11Slide12Fish respirationWater flows over gills as fish opens mouth and swims.Water flows opposite direction of blood flow.O2 diffuses from the water into the blood.Gills are made of thousands of gill filament.Gill are covered by the operculum.
Slide13Fish circulation Fish heart has 2 chambersSingle loop circulationBlood flows into gills , picks up o2 , goes to the body , returns to the heart.
Slide14Interesting information The bony fish have a skeleton that is made up of bone.You can see , bony fish have a protective covering of scales which are loosely attached to the skin and can even rub off in your hands.
Certain species of bony fish can migrate from fresh water to the salt water and still survive.
