1. 1.
a long-bodied chiefly marine fish with a
cartilaginous skeleton, a prominent dorsal fin, and tooth-like scales. Most
sharks are predatory, though the largest kinds feed on plankton, and some can
grow to a large size.
However due to what psychologists call “primal fear” a lot
of people define sharks in much simpler ways such as long, grey marine creature
that has a huge mouth full of very sharp teeth.
(My mom jokes about them being like enthusiastic and extremely curious
children that don’t attack humans, but instead “play”. Only problem is that
humans are not durable play mates.)

The four most recognised types of shark (out of water and who get mistaken for
each other in the water) are below with their names underneath.
This is the Great White shark or Carcharodon carcharias (Alternative names: white pointer, white shark, white death.) and the shark that is held responsible for most shark attacks in Australia.
This is the Tiger shark or Galeocerdo cuvier. The almost tiger like stripes along the back are part of the reason why they are referred to by that name.
This is the Bronze Whaler or Carcharhinus brachyurus. The Bronze Whaler and Bull sharks are sometimes mistaken for each other for the more defined triangle section at the tip of the tail as well as the more longer, pointed nose despite the colour difference.
And lastly this is the Bull Shark or Carcharhinus leucas. (Alternative names: river whaler, freshwater whaler, Swan River whaler)
