A marine biologist studies sharks. Elasmobranchology is the study of sharks. Sharks resemble the true fishes in external form, but differ from them so widely in structure that they are placed in a class by themselves.
yes
Vaginal fluid attracts sharks.
Absolutely. Sharks are given brutal treatment. Wild sharks are given bad treatment when caught. Many people "fin" them, the process of cutting the shark's fins off and tossing the dying, suffering shark overboard. There's your answer.
Sharks and perches have different skeletons by how sharks by how shark's body are straight and aligned to have quick movement in bodies of water. On the other hand, perch's have rough, rigid scales on their body. On the other hand sharks are made of cartilage (the perch are not).

yes because every living things are organisms
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
There are a great many different aquatic organisms. These organisms range from sea snails and phytoplankton to sharks and whales.
Sharks don't live in symbiosis with other organisms. They don't need to. However the remora, or suckerfish, often attach themselves to a sharks skin. They keep the skin clean while removing debris and eating parasites on the sharks skin.

There is no species of shark that do not eat living organisms.
They are an R-Strategist which means that they make many young for a higher chance of survival but don't take care of their young. BA
Sharks are opportunistic feeders. They will gulp down just about anything that they can get into their mouth. Sharks are not evil, just hungry with a strong survival sense. Larger sharks will not bother with a snack as small as a clown fish, but, smaller sharks get to be larger sharks by eating small fish.
