What are the body parts of a shark?

Answer 1

The Frilled shark has 25 rows of teeth with 300 triangular shaped needle sharp teeth to consume other sea animals that reside in depths similar to the frilled shark itself. It also has 6 slit gills and one under its throat.

Answer 2

It has a snout, nostrils, eyes, mouth, spiracle (neck), labial furrows (cheek bone), gill openings (breathing passages), Dorsal fin spine, First dorsal fin (on back), Pectoral fins ("arms"), Pelvic Fin (lower stomach), Second dorsal fin (near tail), anal fin, precaudal pit (connects the body to tail), Caudal fin (tail), Caudal keel (opposite side of precaudal pit), Clasper (males).

Answer 3

Um, sharks aren't missing any of their body parts (duh), but when it comes to human body parts, well, it's a different story. Sharks obviously don't have arms or legs. Instead, sharks have fins. Just to let you know, fins seem a LOT deadlier on sharks than dolphins. Even though sharks don't have what we, humans, have; sharks have many other unique characteristics such as the fact that if they loose a tooth a back up is redy to spring right in to its place, the jaw bone can come out of socket in order to catch prey and then snaps back like a rubber band, sharks have cardilage for their spine instead of bone in order to float, sharks can smell from miles and miles away, and many other things that make sharks unique. If you have read this whole answer, then please DO NOT be afraid of sharks. I have learned that only three sharks actually kill humans and that there are about three deaths per year by sharks. I do have some insight on the information, though. One is that there are more deaths per year by pigs, crocodiles, alligators, dogs, cows, and other animals than there are by sharks. The second thing is that human beings kill thousands to millions of sharks each year for different things, such as shark-tooth necklaces. So, remember, humans may be afraid of sharks but sharks are even more afraid of us. I know I got off topic, but I just wanted to let you know.

Mouths

The position of a fish's mouth gives a general indication of where it feeds in the water column. In an aquarium, fish with up-pointing mouths like hatchet fish primarily feed on the food flakes that float or hang near the water surface. Some fish with mouths on the underside of their head, like the catfish, feed on the bottom. A catfish would be very beneficial to the Aquademics™ aquarium because, as a bottom-feeder, it helps eliminate unused food buildup by eating the food particles that sink to the lower levels of the tank.

The shape and size of a fish's mouth can also tell you what it eats. Since tropical fish in an aquarium have small mouths, Tetra has developed a variety of small fish food flakes, granules and tablets for daily feedings.

Breathing Underwater

Fish, like most organisms, need oxygen to survive. The oxygen that fish "breathe" is dissolved in the water. The oxygen enters the water surface by diffusion or in the water from plants as a byproduct of photosynthesis. Water enters the fish's mouth, moves across the gills and passes out the gill slits or operculum. The gills are made up of a bony or cartilaginous arch supporting a large number of paired gill filaments. Numerous small projections with very thin membranes on each filament are the sites of gas exchange(oxygen to carbon dioxide). Beneath the thin membrane is a network of blood vessels. Oxygen diffuses from the water through the membrane into the blood and carbon dioxide diffuses outward.

Senses

Sight:

Most fish have well-developed eyes on the sides of their heads. This placement allows them to see in all directions. The structure of the eye is very similar to that of other vertebrates. In fish, focusing on near and distant objects is achieved by moving the lens backward and forward by muscular action. Fish that are colorful can probably see in color. Bony fish that are active at night have large eyes that help them see in the dark.Smell:

Fish can smell odors in the water with receptors inside blind sacs, called nares, located on the head. Nares are similar to our nostrils, but fish do not use them to breathe. The sense of smell is well developed and is useful in detecting distant odors.

Taste:

For fish, taste is more of a close range sense. Taste buds, which can be found on different parts of the fish, are used in the identification of food. Taste buds are located in and around the mouth, and, on some fish, on the skin and even on the fins. Barbels, whisker-like structures near the mouth of fish such as catfish, are covered with taste buds and are used in locating food.

Hearing:

Fish have ears but they do not open to the outside and cannot be seen. Hearing in fish is well developed, however. Water carries sound much better than air and the sound waves are picked up through the fish's body.

Lateral Line:

A line of holes runs along both sides of a fish from the head to the tail. The holes have nerve connections that are sensitive to vibrations. The lateral line is used form schooling, avoiding obstacles and detecting prey and predators.

Electroreception:

Some bony fish can detect weak electrical fields through pit organs on their heads and faces. This ability is used for locating prey (all living things give off weak electrical fields), avoiding obstacles in murky water and in migrating.

Buoyancy

Neutral buoyancy, the ability to remain motionless in the water without rising or sinking, is of great importance to a fish. It allows a fish to spend energy feeding, escaping predators or mating that would otherwise be needed to maintain its position in the water. Several strategies help achieve neutral buoyancy. Most bony fish have a structure called a swim bladder, which is a balloon-like organ in the body cavity. Gases from the blood are added or removed to control buoyancy at different depths.

Answer 5

They survive because they live off of dead and alive animals that live in the ocean.

Answer 6

we should take our fingers and put it in the sharks nostrils , it will stop breathing and die or not attack you
