Part 2

Name 3 of the 5 major characteristics of vertebrates.

Have a Backbone (vertebral column, spine) The vertebrae enclosed and protect the nerve cord They have a complex brain – nervous system Bilaterally symmetrical body plan Presence of an endoskeleton

Name 3 of the 5 human uses for fishes.

Humans have many uses for fishes: They provide a vital source of protein They can be ground up and used as fertilizer or chicken feed They can be used to make leather, glue, vitamins, as well as many other products They provide a sport for sports fisherman They can also be kept as pets

Hagfish are also know as slime eels Hagfish are also know as slime eels. Explain how they received this name.

The hagfish excrete a protein that when mixed with water forms a slime like substance that will help protect them from predators.

Explain the function of spiracles on sharks and rays.

The spiracles allow water to enter into the shark when their mouth is occupied.

Explain the difference between the teeth of the shark and the teeth of bony fishes include the purpose both serve according to their feeding habits.

The teeth of sharks are triangular and there are many rows of them The teeth of sharks are triangular and there are many rows of them. This allows the shark to lose teeth when they are feeding on prey. The teeth of bony fishes are fused to the jaw so they are not intended to be lost when obtaining food.

Explain the function of the ampullae of lorenzini and how they work.

Name 3 reasons why sharks are extremely vulnerable

Sharks are vulnerable because they… Mature late in life Have few offspring Have long reproductive cycles Often have specific mating and nursing areas Are highly migratory

How do sharks get their buoyancy and how do bony fishes get their buoyancy?

Sharks get their bouyancy from their liver and bony fishes get their bouyancy from their swim/air bladder.

Do fishes have a closed or open circulatory system Do fishes have a closed or open circulatory system? _____________ Explain why one chamber of a fish’s heart is larger than the other(s).

Closed One chamber is larger because it has to pump blood to the rest of the fishes body where as the other chamber just has to move it into that larger chamber.

Label Stomach Intestine Explain the function of the internal structure of the stomach and intestine.

F is the intestine B is the stomach The intestine has a spiral structure to it so that it takes longer for the food to go through the system and therefore the shark can absorb more nutrients. The stomach has folds in its structure so that it can expand when it eats something large.

Explain the process of osmoregulation and why it is necessary for fishes?

Marine fishes actually have blood that is less salty than seawater therefore, they lose water by osmosis. They need to replenish lost water or they will dehydrate, therefore they osmoregulate. They do this by swallowing seawater. The salt from the seawater is excreted by the kidneys.

Explain the how the lateral line functions?

The lateral line is a line of fluid-filled canals that run along the sides of a fish. The lateral line system allows a fish to detect movement and vibrations in the water so that they can swim in the dark or through complex coral reefs.

The following is a picture of the entrance to a tourist shop in Myrtle Beach. Explain what is anatomically incorrect with this picture.

Has too few gill slits. Sharks have 5-7 gills Has too few gill slits. Sharks have 5-7 gills. There is also only one row of teeth where as sharks should have many rows in a conveyer belt like fashion. The eyes seem more cat-like then shark-like. Although some sharks have white around their pupils they don’t tend to be so slivered like cat eyes can get. Also, the pectoral fin seems to not fit the scale.
