1: Classification Kingdom-Animalia Phylum-Chordata Sub Phylum-Vertebrate Class-Fish Order-Jawless Fish,Cartilaginous Fish, Bony Fish
2: How Fishes Obtain Oxygen | Fishes get oxygen from the water. As the fish swims along the ocean it opens it's mouth and takes a gulp of water. The water, which contains oxygen moves through the openings in the fish's throat area which leads to the gills. As the water flows over the gills oxygen moves from the water to the fish's blood while the carbon dioxide moves out of the blood and into the water.
3: How Fishes Move | Fishes move by the help of fins. Fins provide a large surface to push against the water. A typical fin contains a thin membrane stretched across bony supports.
4: How do they feed? Fishes hunt for most of their food. Some fishes bodies are adapted for efficient feeding. Some of the carnivores have sharp teeth to stab other fishes. Insect-eating fish have short teeth so they can crush their prey. Filter feeders use comblike structures on their gills to filter tiny animals and plants. The jawless fish is a predator because it preys on other fish by sucking, scrapping, or stabbing them. The cartilaginous fish are predators because they have jaws. The bony fish have a hard bone helping them to escape predators.
5: Biomes by Class Fish are apart of freshwater and marine biomes. The freshwater biomes are important because the important factor is sunlight. Animals that live in ponds, lakes, streams, or rivers are qualified for this category. The marine biomes are the habitats differ in sunlight, water temperature,wave action, and water pressure.
6: Era/Period Fish are apart of Paleozoic Era. They are found around 505 millions of years ago. They are in the Ordovician Period.
7: Jawless fish are parasites that crawl into dead or dying fish and eats the the host's tissues.They do not have jaws. | Behaviors | Bony fish have skeletons of bone and have flaps to release water also they have swim bladders. | Cartilaginous fish are all carnivores and filter feed on the ocean floor. its skeleton is made of cartilaginous
8: What Type of Symmetry do Fishes Have ? | All fishes have bilateral symmetry. If you were to cut a fish in half both sides would be mirror images of each other. | As you can see from the picture they are mirror images of each other.
9: Fish Food Web | Food Web In food chains all of the organisms are very important. If you were to take one out the entire food chain would collapse because one of the organism eats that other organism that was taken out so if they can't eat it then they die and the same things happens again until there is nothing else left.
10: Fish reproduce using external fertilization. External fertilization is when the eggs are fertilized outside of the female body. The males goes to the female and spreads a cloud of sperm onto the eggs as she releases them. Some fish like sharks have internal fertilization in which the eggs are fertilized in the female's body.
11: fish have been food For people for many years but overfishing has endangered many types of fish like the Atlantic codfish. Some countries like the United States has tried to stop overfishing by raising fish in "fish farms". This can reduce the demand for fish.
