Top 12 sharks of all time dangreous

Top deadly Sharks


1. ANGEL SHARK:Image result
  • flat body like a stingray -- you can tell the shark is not a ray because the pectoral fins are not attached to the head.
  • They bury themselves in the sand or mud with only the eyes and part of the top of the body exposed.
  • They are bottom feeders, eating crustaceans like clams and mollusks and fish that are swimming close to the ocean floor

  • filters plankton from the water using "gill rakers"


blacktip reef shark3. BLACKTIP REEF SHARK (Carcharhinus melanopterus):

  • Blacktip Sharks are different than Blacktip Reef Sharks (this confused me for quite some time)! 
  • They are usually about 5 feet long although the longest on record was about 9 feet long.
  • during breeding season every February and March, around 10,000 congregate along the Florida coastline.  It's like spring-break vacation for sharks!

  • sleek, tapered body

  • diet consists mostly of squid, but it will eat almost anything

  • very uncommon and likely the strangest looking shark (rarely seen the photos were actually taken in 1909)
  • pale, pinkish grey skin with a long pointed snout (it looks a bit like a sword on top of its head)

great white shark9.GREAT WHITE SHARK:

hammerhead shark photos10.HAMMERHEAD SHARK:
  • unlikely to attack people, but considered dangerous due to its predatory nature and its size (10 to 20 feet)
  • eyes and nostrils are far apart, giving it a "hammerhead" appearance and allowing the shark to extend the range of its senses.
  • their favorite food is stingrays.  Luckily for the sharks, they're immune to the stingray's venom.

mako shark11.MAKO SHARK:
  • fastest swimmer (43 miles per hour)

  • bottom dwelling shark
  • thin, fleshy, whisker-like organs on the lower jaw in front of the nostrils that they use to touch and taste
  • hunt at night, sleep by day

This shows us a big level of ocean life with these creaturs and in ammazone every year almost 50 new types of sepisies are founded.
