If sharks had legs, they would not be sharks.
They will die.
the producers would decrease in population as the herbivores which the sharks would have ate, would grow in population.
You probably never learned this because SHARKS DON'T HAVE LEGS!!
because they don't have legs;)
no they have fins and tails but no legs or arms :)
The legs of insects and the legs of mammals are usually jointed. This does not take into consideration, though, that sharks, whales, and dolphins are also mammals.
there would be too many fish in the sea way too many so sharks are important to keep the fish population down if they did not exist there would be too many fish
If you are talking about fish sharks then I don't think they have any legs they just have fins.
The grasshopper wouldn't be able to jump!
Sharks are a big part of every sea ecosystem so if they become extinct most of the ocean ecosystems would be destroyed.
Then sharks will become extinct. That's why fishing is a big deal.
Then there would be a break in the food chain and all the animals that sharks normally eat will become more abundant and the food that they eat will become scarcer and all marine life will suffer.
