they have a torpedo structure
No, because a shark is not a bony fish as it's skeletal structure is made of cartilage.
the difference between the two sharks are as two simple things. one the gummy shark is a bottom feeder and has sand paper teeth the spinner shark in aerodynamically shaped body meant for hunted fast pray like fish and small sharks and the gummy shark in not a fast swimming shark and feeds from the bottom of the see floor for shell fish and slow creatures
There are many similarities and differences between a shark and a whale. The similarities is that have a similar streamlined body structure but the differences are many including sharks are fish while whales are mammals, sharks have a vertical tail structure while whales have a horizontal one among others.
Sharks are cartilaginous fish. The term "cartilaginous fish" means that the structure of the animal's body is formed of cartilage, instead of bone. A shark does not have one bone in it's body. It's skeleton is made up of cartilage. Cartilage is a tough material, like the material that shaped your ear.
The scientist could infer the type of food the shark ate by examining its teeth and jaw structure. Sharp, pointed teeth suggest a diet of fish, while flat teeth indicate a diet of mainly crustaceans or mollusks. The way the teeth are arranged can also hint at how the shark caught its food, whether by slicing through flesh or crushing hard shells.
The gills of a dogfish shark are highly adapted for respiration, featuring numerous filaments and lamellae that increase the surface area for gas exchange. This structure allows for efficient extraction of oxygen from water as it flows over the gills. Additionally, the gills are located in a series of pouches, which enhances water flow and maximizes oxygen absorption, ensuring that the shark can meet its metabolic needs while swimming.

The inside of a shark contains organs such as the liver, stomach, intestines, and reproductive organs. Sharks have a cartilaginous skeleton (made of cartilage rather than bone) and powerful muscles that enable their swimming and hunting abilities. Overall, the internal structure of a shark is adapted to its predatory lifestyle in the ocean.

The indentation in the tail fin of a shark is called a "lobe." Sharks typically have a heterocercal tail, which means that the upper lobe is longer than the lower lobe, providing lift and propulsion. The shape and structure of the lobes can vary among different shark species, contributing to their swimming efficiency and maneuverability in the water.
