Seals and Sea Lions. They both have similar apperance to a shark. Sharks do not have very good sight, so it is easy to mistake
sharks are killing people such as Hawaiian surfers
yes
Yes especially surfers because from below paddling surfers look like swimming seals
Great white sharks often mistake surfers for seals, their primary prey, due to the silhouette created when a person is on a board in the water. The contrast between the dark board and the lighter water can resemble a seal's shape and movement. Additionally, the splashing and paddling actions of surfers may further attract their attention, leading to accidental bites rather than intentional attacks.
That's what happens when your in the water
Sharks are considered fish because they are fully aquatic animals. They have gills, and they will never come out of the water without human aid.
The reason sharks are dangerous. is the same reason bears or any other animals are dangerous. When they think they are in danger or you are threatening to them they will automatically switch to self defense mode and will then attack. You never want to touch a shark corner it or splash make quick movements or do anything of that sort or they will believe that you are wanting to hurt them or you are personalizing their territory and attack. So whatever you do do not show or do anything like that and you will be fine.
You can drown, obviously. But there are also sharks and poisonous fish Sharks! Although more people are killed each year in Hawaii from coconuts falling on their heads than from shark bites, shark attacks just get more media coverage. Also the reason sharks attack surfers, is because the surf boards make the surfers look like seals from the sharks point of view.
"Blue Crush" is a movie about surfers in Hawaii, not sharks. Another movie that involves sharks in Hawaii is "Deep Blue Sea," where genetically engineered sharks wreak havoc.
As strange as this may sound, when a shark encounters a human beeing in the water, there is a very high probability this shark has never seen before such a «strange fish» in the oceans. Usually the shark feels curiosity, but also caution. He is intrigued, and keeps distance, unless it is provoked attacked. But sharks (specially Great Whites) may mistake surfers by seals. If this happen, a shark attack may occur.
No! Sharks are less mean then your average honey bee! you may think sharks are just big bad eating machines, but they really aren't. Some scientists think that sharks are only taste testing us. they don't have hands do they? they are like babies, or puppies! they do the same things to shark motors. Other scientists believe, sharks mistake us for large sea animals suck as seals. From the bottom that's what we look like, especially when we are on surf boards! So to answer your question, no sharks not the meanest animals in the world.
